[SOLVED] How to restore Petitboot on HC-4
Hi,
it seems like my firmware / Petitboot is broken on my HC4.
Only the red light is on after power connection, no flashing blue light anymore. If I keep pressing the switch at the bottom of the case (to enforce boot from SD Card), it works with your Ubuntu Mate image provided.
But I always have to keep pushing this button at boot time.
Where can I please get the HC4 Petitboot firmware image and how to restore it?
You can assume I made a mistake like "Exit to shell" , run "flash_eraseall /dev/mtd0" in the command line of the Petitboot"...
Thank you for your kind help in advance.
Best regards,
Frank

Re: How to restore Petitboot on HC-4
Where did you get the command "flash_eraseall /dev/mtd0"? And why did you try? Doesn't it boot from SD card after the command?
Download "spiupdate_odroidhc4_20201112.img" from the link, and flash it to SD card. Boot with SD card while keep pressing the switch until the blue LED on, then the SPI flash memory will be restored.

Re: How to restore Petitboot on HC-4
Hi,
I got it from this post: viewtopic.php?p=310908#p310908
After numerous tries, I got it to work with my HDMI screen (without doing anything special but kept trying). Then I did the stupid mistake of deleting Petitboot (my bad).
Now the blue light is back (not flashing though) and I am back with my initial problem again, no HDMI output visible...

Re: How to restore Petitboot on HC-4
Hi, sorry, do not get it to work. Did create the image as you suggested. Pressing button during power on, then blue light blinks but nothing else happens. No HDMI output whatsoever.
If I use the Ubuntu Mate SD card, do the same (push button during power on), it boots into Mate and all is fine.
Any idea what else I could do? Something from within Ubuntu Mate with ODROIDBIOS.BIN maybe?
Without manual intervention during power up, the device does not boot anything, not even Ubuntu Mate.
THX for you kind help in advance.

Re: How to restore Petitboot on HC-4
Are you sure you have flash the image with Etcher and let it start with button pressing on the bottom? When the blue LED blinks, it boots. If you are not able to see HDMI, why don't you let it be for 10 minutes? Maybe it would recover it while showing nothing.fkreuz wrote: ↑Sun Nov 15, 2020 6:49 amHi, sorry, do not get it to work.

Or you can try another image,
http://ppa.linuxfactory.or.kr/images/pe ... 201101.img
Other OS image cannot recover SPI flash memory. So please try again with the images I shared and let me know so I can help you.

Re: How to restore Petitboot on HC-4
Sorry to say, no success. Did find an old monitor now which shows a screen, do get by pressing the button at power up to a menu.
One time during boot it said something like "invalid SPI partition for firmware".
However, nothing else happens, no automatic flash process etc.
Any way to enforce it to re-install the initial flash?`
THX for any help in advance.
screenshot from boot screen:

Re: [SOLVED] How to restore Petitboot on HC-4
Dear People
yesterday I received this odroid board
After powering it up it booted into petitboot so I assume everything was working.
I did not use the network installer since I wanted to install from sdcard (try some distro's first before deciding what to pick)
and since my plan was first to try to install raspbian the first thing I did was removing petitboot following this guide https://www.armbian.com/odroid-hc4/using these commands:
After writing the armbian image to SD card I tried to boot the machine but no matter what image I use I am not able to boot, all I see is a blinking cursor in de upper left corner on my HDMI attached screen.
After this I tried the above guide to restore petitboot to try the netinstaller, but I run into a problem: when flashing the drive with the different images I'm not able to restore petitboot
Here's what I'm donig
- flash sdcard with several images from http://ppa.linuxfactory.or.kr/images/pe ... 201101.img
- take out the power cord
- insert the sdcard into the slot
- use a pencil to press the button on the bottom of the machine
- with the button still pressed I put in the powercord
Everytime the red light start to blink continuously I no matter how long I press (even up to 20 seconds) I don't see the blue blinking light start.
I asume the blue blinking light would indicate that petitboot is being written to SPI.
I also tried to continuously click the button with short clicks but also nothing happens except for the red led blinking.
I also tried a different sdcard with no change in effect
Now I have 2 questions
1. Is this the correct procedure to restore petitboot?
2. Can someone help me out how to get this problem solved?
Thanks already for your advise.
Daf

Since you have erased the SPI flash memory, you do not need to press the button on the bottom. So...please do try reinsert the power cord without pressing the button.
What's the vendor and the model of your SD card?I asume the blue blinking light would indicate that petitboot is being written to SPI.

Re: [SOLVED] How to restore Petitboot on HC-4
Dear tobetter, thanks for your quick respons!
I'm currently at the office so I cannot do a proper debugging however to answer your questions:
- the red light is just burning, not blinking, there's no blue light.
- I use 2 GB kingston SD card, I will have to check to exact number/type.
- what behaviour will he lights show when flashing the SPI?

The red LED means power is supplied, the blue LED is on only when a bootloader is started then start to blink when Linux kernel is started.dafart wrote: ↑Fri Aug 20, 2021 6:05 pmDear tobetter, thanks for your quick respons!

The Kingston SD card is not very compatible with ODROID boards, you "must" use other SD card (UHS-I grade) and this will work.
The blue LED will blink when SPI recovery is started.

Re: [SOLVED] How to restore Petitboot on HC-4
Dear tobetter, thanks for your support, I bought a samsung UHS-I microSD card and it got recognized straight away, now petitboot has been restored and looks like the device works as it should.
Never realized the brand / type of microSD card would make a difference...
Kind Regards
Daf

Re: [SOLVED] How to restore Petitboot on HC-4
I have the same problem. We tried to recover as the answer to the article was written, but the boot partition inside the damaged odroid does not seem to be able to return. Petiboot is installed only on the sd card, so in order to enter petiboot, you have no choice but to boot by pressing the button at the bottom. What should I do to boot without an SD card?

Re: [SOLVED] How to restore Petitboot on HC-4
It's a bit confusing, are you going to reinstall Petitboot in SPI flash memory or do you want to recover OS installed on HC4? What do you mean by exactly the Petitboot is installed on the SD card?

Re: [SOLVED] How to restore Petitboot on HC-4
In order to restore the SPI flash memory, flash the image in the link using Balena Etcher to SD card and insert to SD card slot. Before connecting power adapter to HC4, keep pressing the black button on the bottom until the blue LED turns on. This image will start to flash SPI flash memory with Petitboot firmware, remove SD card once it's done.archethic wrote: ↑Wed Jan 19, 2022 6:04 pmIn the situation I want, I want to enter petiboot without the user's manual input with the SD card separated.

Re: [SOLVED] How to restore Petitboot on HC-4
We are talking about how Petitboot can be recovered, the image the image in my previous post is to reflash the Petitboot in SPI flash memory. Once it's done completely, remove SD card and check if the Petitboot boots or not. If you encounter an any issue, please describe what you did so I can help you futher more.archethic wrote: ↑Fri Mar 18, 2022 6:45 pmThanks for your help, I'm a bit late.

This image will start to flash SPI flash memory with Petitboot firmware, remove SD card once it's done.archethic wrote: ↑Wed Jan 19, 2022 6:04 pmIn the situation I want, I want to enter petiboot without the user's manual input with the SD card separated. Maybe we need to restore the SPI partition to solve it. However, I couldn't recover even if I tried all the solutions above.tobetter wrote: ↑Wed Jan 19, 2022 5:18 pmIt's a bit confusing, are you going to reinstall Petitboot in SPI flash memory or do you want to recover OS installed on HC4? What do you mean by exactly the Petitboot is installed on the SD card? Did you remove the Petitboot flashed in SPI?archethic wrote: ↑Wed Jan 19, 2022 5:14 pmI have the same problem. We tried to recover as the answer to the article was written, but the boot partition inside the damaged odroid does not seem to be able to return. Petiboot is installed only on the sd card, so in order to enter petiboot, you have no choice but to boot by pressing the button at the bottom. What should I do to boot without an SD card?
