Petitboot, yet another bootloader based on KEXEC

[tobetter]

20200816

Update version from 20200806 is uploaded. The firmware can be updated in the Petitboot itself by running the command 'pb-update', or you can download firmware file from spiboot-20200816.img and copy it to your SD card as spiboot.img.

What's improved:

• Quick fix for CoreELEC 9.2.4.2 - CoreELEC made a change on 'boot.ini' with the command that was not supported in the Petitboot, the command is applied.

In case if the Petitboot update is failed and no longer boot from SPI memory while ODROID-N2 can boot from eMMC or SD card, SPI flash memory needs to be recovered. Please refer to the link for the detail of how you can recover the SPI flash memory, the recovery image can be downloaded from spiupdate_odroidn2_20200816.img.

Thanks, for N2, I updated with pb-update without any problems.
All my OSes are working fine.

Update version from 20200721 is uploaded. The firmware can be updated in the Petitboot itself by running the command 'pb-update', or you can download firmware file from spiboot-20200806.img and copy it to your SD card as spiboot.img.

What's improved:

• Microsoft keyboard driver, but not tested if it works since I don't have the keyboard.

With the above (hash sum 448c836dde45ffb47c8806ef79daaa56), the (wired) "Microsoft Natural Ergonomic Keyboard 4000 v1.0" still does not work for me, unfortunately. Is there any information I can provide to make it work?

Here is an odd issue. I wanted to give my N2+ Ubuntu install more storage space so I set up root on NFS. I modified /media/boot/boot.ini to comment out the existing bootargs line, then set a variable for the NFS share and modified the boot command as follows:

Code: Select all

setenv nfspath "192.168.1.139:/srv/n2plus"
setenv bootargs "boot=nfs root=/dev/nfs ip=dhcp nfsroot=${nfspath} rootwait rw ${condev} ${amlogic} no_console_suspend fsck.repair=no net.ifnames=0 elevator=noop hdmimode=${hdmimode} cvbsmode=576cvbs max_freq_a53=${max_freq_a53} max_freq_a73=${max_freq_a73} maxcpus=${maxcpus} voutmode=${voutmode} ${cmode} disablehpd=${disablehpd} cvbscable=${cvbscable} overscan=${overscan} ${hid_quirks} monitor_onoff=${monitor_onoff} logo=osd0,loaded ${cec_enable} sdrmode=${sdrmode} consoleblank=0"

The default bootargs line is:

Code: Select all

setenv bootargs "root=UUID=e139ce78-9841-40fe-8823-96a304a09859 rootwait rw ${condev} ${amlogic} no_console_suspend fsck.repair=yes net.ifnames=0 elevator=noop hdmimode=${hdmimode} cvbsmode=576cvbs max_freq_a53=${max_freq_a53} max_freq_a73=${max_freq_a73} maxcpus=${maxcpus} voutmode=${voutmode} ${cmode} disablehpd=${disablehpd} cvbscable=${cvbscable} overscan=${overscan} ${hid_quirks} monitor_onoff=${monitor_onoff} logo=osd0,loaded ${cec_enable} sdrmode=${sdrmode} consoleblank=0"

As you can see very little has changed. However...

Since my first boot with root on NFS I cannot get video output in Android or Ubuntu after exiting Petiteboot. If I do use Petiteboot (by setting the SPI switch) video works fine but I cannot choose which storage device to boot from. This is not optimal but it works because the eMMC will boot Android by default. To use Linux I must move the switch to SPI mode then let Petiteboot load and then the uSD card will boot by default. Even though there is no video output I can ssh in from my desktop. If I want a gui I set up VNC.

I cannot offer proof that changing the bootargs line is what is caused this to happen. It is just the last thing I did before the issue started. For me it isn't a terrible problem but for others it might be. What do you need me to do to help?

Ugh. Sorry for the noise--I just saw that the menu still mentioned version 20200721, although I originally copied the spiboot.img to the SD card, rebooted, saw that an upgrade finished successfully, rebooted[x] again, and the image file was gone.
This time, I copied the very same 20200806 image to the same location, rebooted, immediately exited to the shell and ran pb-update (using another keyboard, of course). After rebooting[x] again, now I have version 20200816(!) and the Microsoft keyboard works with Petitboot (this time, the (unused) spiboot.img file was still on the SD card, so I deleted it manually).
(For the record, the keyboard always worked with all kernels 4.9.x and 5.7.x I've tested so far, the problem was with Petitboot only.)

Ok, so the Microsoft keyboard works with the version 20200816. Thank you for the confirmation...I was looking into the price of the keyboard. By the way, if you can run pb-update and it performs the update, you don't need to copy spiboot.img any more. Please use pb-update when the new version is released.

I have updated my N2 to the latest version of coreelec, and also updated petitboot as required.

After running spi-update, my petitboot updated to the latest, however now I am stuck in an infinite boot loop and am unable to boot into coreelec. My Corelec is on an external usb 3 drive, it has worked perfectly up until the latest update.

It appears as if petitboot on my external drive is corrupted. When i unplug the usb drive, my system boots with a working petitboot . I can then plug in my usb3 and the working petitboot will recognize it. If i boot with the external usb 3 already plugged in (as it had been for months prior), it causes an endless boot loop where petitboot cannot properly initiate (in fact keyboard doesnt work at all for the few seconds it shows)

I tried downgrading, to no avail, by placing the august 15 version of petitboot onto a micro sd, and renaming it spiboot. No luck

Any help would be appreciated!

If you have the latest CoreELEC, you should not downgrade but must use the Petitboot after 20200816. Looks like your Petitboot is compromised for some reason, please do update with the Recovery Image.

CoreELEC 9.2.4.2 on 64GB eMMC (just waiting for the CE Nightly versions to be released in order to switch to them)
LineageOS16 on SanDisk 64GB uSD

I was also able to change the boot order from the default Android to CoreELEC. SPI button on the left now boots CoreELEC by default and I can select android when needed with no problems. However, I did test the SPI button on the right... and android boots. Not sure if this is normal?

Looks like it's not normal but it's possible when eMMC does not have U-boot, then LineageOS16 will boot from SD. Have you tested without SD when the boot select switch is placed at right?

I followed all the steps you had mentioned. I am still getting never ending boot loop after spiboot is recovered with my usb 3 drive plugged in upon boot. If i unplug it, then boot, petitboot loads perfectly. (see here : https://ibb.co/sF98pZM) I can then plug in my usb 3 device and boot from it this way only. If I leave it plugged in upon booting, it again leads to never ending boot loops. Any help would be appreciated.

see here for infinite boot loop behavior - only with usb3 external plugged in : https://streamable.com/pvcjxd

EDIT : I wiped the external drive completely. same result! My system is still unable to boot with the drive plugged in. It causes a never ending boot loop . I am also unable to control anything with my keyboard.

Yes, also tested this. SPI on the right, with eMMC installed and no uSD boots CoreELEC with no problems.

I also learned that I cannot switch the SPI button to the right, while CoreELEC is running. Rebooting CoreELEC still showed me Petitboot on bootup, even with the SPI button on the right side. I tried many reboots to no avail. I had to unplug the power cable to finally not show Petitboot on boot while SPI button was on the right.

The boot select affects when the power cable is replugged, reboot won't affect it.
The switch is not to select boot from eMMC or SD, it selects between SPI or others and others has the boot priority that eMMC is higher than SD.

I just found a consistent pattern for boot failure on my N2+ w/Focal 20.04 w/Gnome/Wayland/5.7. Pretty sure it happens with my regular N2's as well.
I run this test several times just to make sure it wasn't some random events.
Used latest 20200816 Petiboot, it was happening with previous Petiboot version as well.

This just involves failing boots with a fully working USB3 to SATA adapter and my Samsung Evo 860 SSD's. See my Picky USB3 to SATA adapter issues post for reference.

- If I hit enter on my SSD drive as soon as Petiboot detects my USB3 SSD drive, which is almost instant(Using the right and compatible USB3 to SATA adapter of course), then my Focal 20.04 w/Gnome/Wayland/5.7 booting process fails. It gets stuck with a blinking cursor right before showing Ubuntu Login Screen. This happens, specially after a power-cycle and fails in 4 out of 5 attempts.

- If I wait 4-5 seconds after SSD drive is shown by Petiboot, then it successfully boots 7 out of 7 times.
I don't know what additional processes are required to load by Petiboot in order to accomplish a successful boot.

When I receive my official USB-to-UART module kits will be able to find out more.

I fixed my issue by doing the following :

1) Ensuring that only one usb 3 device is plugged in upon boot (with emmc and sd card also in place). With two, it causes the issue. (I had an external hdd also plugged in during boot, ontop of my usb 3 external nmve)

thats all!

Not sure if it is intended that multiple usb 3 devices not be plugged in upon boot.

good evening, I have an odroid n2, I installed CoreELEC on emmc with Storage on USB and SD Android, the problem is that I updated petitboot to the latest version of August 16 and now it basically doesn't start Coreelec anymore, I better wait for a new one correct version? Before, everything worked perfectly. I tried to go back with the versions but everything froze and then I went back to the latest version. Thank you.

Petitboot (v20200816) is fixed version for CoreELEC 9.2.4.2. Are you able to see the boot entry of CoreELEC but cannot boot or even the boot entry is missing?

[marcavatar]

Vedo tutto ma non si avvia, carica lo schermo ma rimane nero con la luce blu lampeggiante, considera che coreelec è su emmc e chiavetta usb, prima avevo la versione 27112019 e funzionava egregiamente, non ho mai fatto nessun upgrade a versioni più recenti.

[marcavatar]

Hi, in reference to the last post I tried to load CoreELEC on the screen, the screen remains black but the program is active, I first tried via ssh to see if it responded and the answer is positive, then furthermore I tried to display CoreELEC on the screen of my fixed windows pc with VNC Viewer via VNC connection and it shows and I can operate it, so the problem is that it is not seen on the main screen, maybe there is an hdmi problem, what do you think?

[Sholander]

Does CoreElec boot and work normal when only eMMC is attached? If not, state your problem on CoreElec forum: https://discourse.coreelec.org/

I can also confirm that on petitboot 20200806 and 20200816 that multiple USB3 disks plugged into the N2 cause a boot-loop with petitboot. Unplugging all disks except the boot drive (which remained in the top left USB slot the entire time) allowed petitboot to run normally. It promptly recognized sda1 and auto-booted from there. Once past petitboot, I plugged the other 3 disk enclosures back in and had no issues.

Are you trying to set up the netboot installer server in your local network for a private or for mass production?

For your questions:
1. Not necessary to download the Netboot installer image. PXE boot configuration can specify the files to start the Netboot installer as "KERNEL", "INITRD", "DTB" and "APPEND". Actually, your PXE configuration is to use the files after Netboot Installer image is started which is not necessary. Please refer to my PXE configuration that starts Netboot Installer. The Petitboot is capable to download the booting images using HTTP protocol, not only using TFTP.

I'm struggling to get Petitboot to work and I would appreciate some help.

I installed 20200816 with what seemed no problems and after install it rebooted. I still had the SD card I installed from inserted and the switch in the right position and the menu was displayed. However as soon as I power cycle and move the switch to the left I get nothing. The blue LED comes on but there is no video output. There is also no response from the keyboard (caplock light does not come on etc.) I have tried installing again with the exact same end result.

Inserting a SD card, putting the eMMC in or having nothing inserted makes no difference.

You need to recover the SPI flash memory with the recovery image, not update image. This is the link to the latest version.

You need to recover the SPI flash memory with the recovery image, not update image. This is the link to the latest version.

And this is the instruction on how you can recover the image.

Can you share the photo of the board that shows the boot select switch?
Did you flash the spiupdate-*.img to SD card using Etcher?

EDIT: Can you try to boot without eMMC attached?

Since you have the USB-to-SERIAL debugging board, let's try this.

When you boot your ODROID-N2PLUS while the debugging board is attached, stop at U-boot by pressing a key from Putty so that you can run a command sf probe in U-boot. This command will check if ODROID-N2PLUS can detect the SPI flash memory is attached or not. If you have the output like this, size would be different, SPI flash memory is fine otherwise SPI flash memory is somehow defected. It does not matter if the boot select switch is at "SPI" or "MMC" if you can get U-boot.

Code: Select all

odroidn2#sf probe
SF: Detected XT25F128B with page size 256 Bytes, erase size 4 KiB, total 16 MiB

Once you have verified the SPI flash memory, attached the SD card after copying the spiboot.img into it or just reflash the image spiupdate_odroidn2_20200816.img to SD card and run the command in the U-boot again. The command spiupdate_full will read spiboot.im from SD and flash it to SPI in U-boot.

Code: Select all

odroidn2#run spiupdate_full

When flashing with the command spiupdate_full is completed, place the SPI boot select switch to SPI and remove SD card then replug the DC cable. If SPI update is success you would have the Petitboot. Please try this and let me know how it goes.

In addition, from the photo of your ODROID-N2, the RTC battery is wrongly inserted. Please refer to the link and reinsert it again.

Hmm...this means no good. Just for sure, would you please check the eMMC connector if it's a dust or the pin is damaged? It's between the pins 7th and 8th from left. One of them is connected to SPI flash memory.

In case you are getting the same error with sf probe in the U-boot, please contact Pollin for RMA if your board can be covered or not.

Indeed, thank you. I think you need to contact to Pollin for RMA if you like to keep working the Petitboot.

Good luck and hope you do not have any issue getting RMA.
Sorry to know this happens, this is the first time I have SPI flash does not work on ODROID-N2/Plus.

Hi tobetter, is it possible (or would it be in future releases) to somehow edit the boot order from an OS that already booted?
I used to do that with an older release editing the petitboot.cfg in the uSD card. But now I had to update petitboot because of the fix for last CoreELEC ‘boot.ini’. And newer versions no longer save the config in uSD, so petitboot.cfg is ignored in my tests.
Another question is if you have plans for CEC or LIRC support?
Thanks for your great work.

The Petitboot configuration is now storing in the SPI flash memory itself, no longer store it to 'petitboot.cfg' since......sorry, I don't remember the version but it's been long. You can change the boot order in System configuration. Due to the lack of SPI memory size, LIRC won't be supported and CEC needs more effort to support it. Out of curiosity, what's the model of the brand of your remote?

I continue to offer my energy and curiosity to get CEC to work as I struggle with it constantly and I want to under stand it.
I moved the Nvidia Shield TV to HDMI on Denon and Panasonic home system and I control and view all the capabilities.
I can ADB into the Nvidia and run any Android app or command to interogate the CEC protocol like I did with the IRC from Hardkernel earlier.
I am also looking at MIDI controllers so just need a way to sniff CEC dialog.

What can I do to help more ?
