I experienced but with another OS image, maybe I would try the same one what you tried.
Could you let me know the exact file name of your Armbian?

The main problem is not armbian I think but in my case petitboot itself. Even if armbian is detected I cannot move the cursor to boot or edit. Every key I press makes petitboot start the shell or makes it reboot. The shell has incorrect terminal behaviour and on exit of the shell the petitboot menu is not repainted.

Btw I think I used Armbian_5.89.

I didn't mention Armbian is the problem.

EDIT: You don't have to move or link the /boot/boot.ini to boot.ini. Current Petitboot has an issue to parse boot.ini of Armbian, the workaround I can offer you today is to modify the boot.ini like below. Since I have no plan to release Petitboot for a few weeks, I only can provide this solution as of now.

@tobetter If I sounded harsh I apologize. I know you are very busy and I am gratefull of the work you do. I just wanted to notify there might be a problem with release 20190626.
For me keep on using RC3 is fine.

No, you didn't...please accept my apologies if I made a wrong. I've tested the image Armbian 5.89, luckily I was making a use case that Petitboot users might be interested in and I was about to test with Armbian. Since Petitboot is not smart to recognize all OS images, it still has to run with others.

The thing is in my case, using a wireless keyboard with a USB dongle, it looks like it can probably boot none. Since the menu is not working I cannot choose what to boot nor edit an entry nor use the shell to check what is going on.

Doesn't the change of boot.ini in my post work? Can you just remove boot/ from the filenames which start with ext4load?

Sorry for being not clear enough. Even if I remove the USB drive (containing the armbian partition) from the N2 petitboot does not work correctly for me. The menu remains unusable.

I don't understand if you remove the USB drive Armbian then what do you have with N2? If you do not figure out with the 201906, even next release won't work.

Well I have to apologize again. I flashed 20190626 again and without armbian image petitboot works. Then I inserted my armbian image and the weird behaviour begun again. Then I applied the fixes you proposed for boot.ini and now it works.
I should have tested better. Thanks for your help and sorry for wasting your time.

NP, good to know it works. Will task some time to make way better in July for update release. Thank you for sharing.

Those who have problems may be using the 2.4Ghz wireless keyboard on USB 3.0 port, please use USB2.0 OTG Cable to fix the problem.

For armbian I only add 1 single line, and move /boot/boot.ini to /boot.ini

Code: Select all

setenv bootlabel "Armbian"

@hungphutho,
Thanks, I know it's your video...

Also, I know the issue of Armbian...I've looked it yesterday with another user in this thread.
That would be resolved a bit later...

I published one article for someone who may be interesting to install two different OS images into single eMMC. The aim of the article is to explain how to compose two OS images usually installed in eMMC and uSD which does not run with the same performance. Using this way both OS will run in the same performance as much as eMMC supports.

https://medium.com/@tobetter/installing ... pe=initial

Since there are limitations some OS is not able to be composed, what I've tested images are:
1) Ubuntu Mate 18.04 + CoreELEC
2) Debian Stretch + CoreELEC
3) Ubuntu Mate 18.04 + Armbian
4) Debian Stretch + Armbian

Instead of CoreELEC, I think EmuELEC would work since their build farm is the same. Also, please note that as some users reported Armbian needs some change of boot.ini even you made to compose the dual-OS memory card, still you will need to change the same.

Also, since this the trial to publish a use case of Petitboot, please do compose at your own risk. Requesting and helping to me is still available.

Great job. If I ever get time I might look into loboris' triple boot scripts - it handled android as well.
One more suggestion. You can create an extended partition and install the second (and third/fourth) OS in logical partitions.

That's true, just personally not prefer to use extended partition.

I was thinking to use GPT alternatively. BUT actually I have something another plan which I want to do and hope to be done some day.

Anyway, thank you for great instresting and I noticed the view count of this thread is already 10+k. Yay!!

201907-RC1

This is the experimental update of only U-boot change and no improvement of Petitboot is included.
If you do not have any issue using ODROID-N2, specifically USB devices, not necessary to proceed the update at all.
https://drive.google.com/open?id=1r9MA2 ... ZwlXbrU9Dp

Please rename the file to spiboot.img and copy to your uSD for update.

I've tried 201907-RC1 to see if there were any changes with my monitor detection. It still goes into standby in petitboot if it is any help.

IgaBiva · Unread post by **IgaBiva** » Mon Jul 15, 2019 9:00 pm

Sorry for a noob question but is there any way to use petitboot without keybord?

I plan to use my N2 for dual boot with CoreELEC and for TheRA (or EMUElec) and I would like to avoid usage of keyboard if anyhow possible.

Can we access boot menu via SSH or Telnet?

mad_ady · Unread post by **mad_ady** » Tue Jul 16, 2019 3:20 am

Yes - you can use the HK IR remote!
You can clone the codes on a universal remote.

IgaBiva · Unread post by **IgaBiva** » Tue Jul 16, 2019 5:51 pm

Great thanks!

I do have universal remote so I will try with this first.

brad · Unread post by **brad** » Tue Jul 16, 2019 6:01 pm

I though about this some time ago and another possible option (if petitboot was updated somehow) might be to hold down a button (or a switch) connected to a GPIO which petitboot used to determine the boot option.

I was going to try to simplify this by using mainline uboot instead of petitboot to decide but I have not had time to get back to it.

IgaBiva · Unread post by **IgaBiva** » Thu Jul 18, 2019 8:13 pm

Well, I believe that ideal solution would be something like PINN in Pi world but don't kow if this is possible - https://github.com/procount/pinn/blob/m ... ME_PINN.md

This would give much more fredom for different options and functionalities.

Unfortunately, I am not a developer so I cannot contribute to this...

That's the features what I am expecting to have in the SPI flash memory along with Petitboot. But due to the capacity of SPI flash memory and lack of resources, the development would go slow unfortunately.

Since Petitboot supports plugin feature, similar feature can be feasible and could be more that that.

Not sure what's wrong, but one doubt is that you have changed the right file. I understand that Armbian has /boot/boot.ini, not boot.ini. Please check if you have two boot.ini.

istanbulls · Unread post by **istanbulls** » Tue Jul 23, 2019 12:49 am

yes I'm modifying the /boot/boot.ini file. I have no idea where the other boot.ini file is

I replace it with "sudo nano"

I published one article for someone who may be interesting to install two different OS images into single eMMC. The aim of the article is to explain how to compose two OS images usually installed in eMMC and uSD which does not run with the same performance. Using this way both OS will run in the same performance as much as eMMC supports.

https://medium.com/@tobetter/installing ... pe=initial

Since there are limitations some OS is not able to be composed, what I've tested images are:
1) Ubuntu Mate 18.04 + CoreELEC
2) Debian Stretch + CoreELEC
3) Ubuntu Mate 18.04 + Armbian
4) Debian Stretch + Armbian

Instead of CoreELEC, I think EmuELEC would work since their build farm is the same. Also, please note that as some users reported Armbian needs some change of boot.ini even you made to compose the dual-OS memory card, still you will need to change the same.

Also, since this the trial to publish a use case of Petitboot, please do compose at your own risk. Requesting and helping to me is still available.

The Armbian-CoreELEC combination works very nicely when I've installed it on the Micro SD card. Thanks

I'm using an HDMI-to-USB converter to boot up the Petitboot menu. This works when I boot up the recovery image with boot.ini edited to have the right video parameters. What do I need to do the actually change the boot.ini image in SPI so that I don't have boot from the SD card with the recovery image?

@mad_ady
I'm trying to replicate the process used to boot into Arch Linux on a USB drive. I'm using an SD card in a USB adapter right now, but if I can get it to work, I'm going to install Arch on a USB HDD and boot into that. Right now, I can boot into Arch Linux using the sd card in the sd slot. I copied your boot.ini, changed the UUID to match the one on my ROOTFS and tried to boot. The blue light stays solid and never starts blinking, so I think the boot is failing. Do you have any ideas of what I'm doing wrong?

mad_ady · Unread post by **mad_ady** » Sat Aug 10, 2019 3:05 pm

@woodyl:
1. Have you flashed the latest petitboot image on this thread?
2. Note that it starts in 1080p mode and you won't get a display if it doesn't support 1080p. What resolution is your display and what do you mean by hdmi to usb?
3. Petitboot scans all attached disks and looks for their boot.inis and parses those. You shouldn't need to use a different boot.ini than what your distribution provides. But I doubt petitboot uses the video settings from bootini for itself.

@tobetter: in order to force a resolution on petitboot I suspect one would need to build it, but where should I try to set the resolution? I might try to tinker next week if I find the time,

Hi,

i very interested in this project.
Sorry to be off topic but how can we use petitboot on an Odroid-C2 device ?

mad_ady · Unread post by **mad_ady** » Sat Aug 10, 2019 9:01 pm

@JrCS: you can't. In theory you could by adding a spi flash chip via the gpio pins, but on C2 spi is used for ethernet, so it can't boot from it.
You might run petitboot from sd or emmc though, but it needs to be built with C2's uboot/kernel. It might be a way to multiboot on the C2...

woodyl · Unread post by **woodyl** » Sat Aug 10, 2019 11:22 pm

@mad_ady
1. I've tried it with both the 20190407 version and the 201906-RC3 version.

2. I tried it on a TV which supports 1080p. I'm also trying to use it with an HDMI-to-VGA adapter which works at 720p.

3. Here's what I think is happening:

Petitboot sees my boot partition on /dev/sda1. I think it parses the boot.ini on the Arch partition but fails for some reason.
Looking at the boot.ini on my Arch installation I see:

Code: Select all

setenv bootargs "root=/dev/mmcblk${devno}p2......

I'm thinking that the boot process is not finding the root partition and that I need to relabel the partitions or use some other directive. If you are successfully booting into Arch, what do you have in the bootargs on your Arch boot partition?

mad_ady · Unread post by **mad_ady** » Sun Aug 11, 2019 3:22 am

Sorry, I'm using ubuntu. But you can experiment with mmcblk0p2 if you're using an emmc or mmcblk1p2 if you're using sd.

karog · Unread post by **karog** » Sun Aug 11, 2019 4:54 am

@woodyl That setenv bootargs is where I suggested over on your arch thread to set root=/dev/sda1 as that is your root partition. Did you try that?

That current setting root=/dev/mmcblk${devno}p2 is appropriate for booting from emmc/sd depending on devno 0 for emmc, 1 for sd I think. The p2 is the second partition because those installs have p1 VFAT for /boot and p2 ext4 for /root. I'm guessing the u-boot.bin there cannot read the ext4. But Petitboot can.

woodyl · Unread post by **woodyl** » Sun Aug 11, 2019 5:56 am

@karog
Yes, I tried setting root=/dev/sda1. When I tried that, the boot fails. I also tried setting root=UUID={uuid for 2nd partition}.

Code: Select all

setenv bootargs "root=UUID=ba0a5962-ab86-4b38-be31-0302338ab7da .....etc..

When I set the UUID as the bootarg, I get a partial boot. The blue light blinks, indicating that kernel was loaded (I think). I also can see that the odroid is getting far enough along that it connects to DHCP and gets assigned an IP address, which I can ping. But the device never completely boots up to the point where I can SSH in or get anything on the display. The fstab only has 1 entry; it mounts the boot directory.

Code: Select all

/dev/mmcblk1p1  /boot   vfat    defaults        0       0

I tried changing the fstab entry to point to /dev/sda1 or to the UUID for /dev/sda1, but that didn't work either. I feel that pointing boot.ini to the UUID is almost there, but something is failing a little way into the boot. Any suggestions appreciated.

woodyl · Unread post by **woodyl** » Sun Aug 11, 2019 6:22 am

Ok, success! I cloned the SD card to a USB hard drive. I changed the bootargs to point root=/dev/sda2. I changed fstab to point to /dev/sda1 for the boot directory. I'm now able to boot into the USB drive from Petiboot. I don't know why it didn't work with the SD card. One difference is that I formatted the the boot partition on the USB drive as ext2. Whatever it is that makes it work, I'm glad to finally get it going!

karog · Unread post by **karog** » Sun Aug 11, 2019 7:53 am

@woodyl Nice perseverance. So you did the two partition solution like on the eMMC and sd. Except you formatted the boot partition (first partition) as ext2 rather than VFAT, right? If so, maybe Petitboot does not understand VFAT.

Did you also set Petitboot to auto boot or do you first go into Petitboot and then have to manually boot?

ETA: I still don't understand why you cannot have a single partition. If you had made the boot partition ext4, would it not work? What if the single partition were all ext2? Of course one would rather have root be ext4.

mad_ady · Unread post by **mad_ady** » Sun Aug 11, 2019 11:22 am

Petitboot can read fat. I think it can read ext4 as well and ext2/3 through the ext4 driver. A serial dump might help to identify the problem.

I'm sure I could make this work with a single partition, and it would probably work with a single ext4 partition. but I decided to keep the boot partition separate. Some people think there are some minor advantages to doing it that way. For instance, you can probably change out the OS in the root partition without making changes to the boot partition.

Petitboot just looks for boot.ini on the 1st partition it sees, then automatically boots. At least that works well on the RC3 version of Petitboot.
