@crispyoz No, I was booting from system, which was installed from usb
@kamiloade Thanks, I've seen this solution and tried it, I guess this is an attempt in the hope to get the same MAC address, which the system will accept as its. But it's about 16^12 combinations, you are lucky to get it so fast

@Lazar-Demin yes, that seems to be the problem, because only the wireless is not working, I tried i2c and spidev, everything is fine. And how can I extract the factory partition from the live chip? Do I need to connect wires to the chip? Do I only need to know the factory MAC address or do I need to have access to the whole chip?

@Lazar-Demin yes, it's the same device. Unfortunately I don't have another device, I bought this about 6 years ago, tried it and put it aside, I think there were problems with it then too. But, when I use openwrt-21.05 firmware, then wireless network and AP go up without errors

Following this post, I updated the bootloader and installed onion_omega2-22.03.3-20230414.bin firmware, all went well, except for wifi. I got these errors:

Disabling radio0 by setting wireless.radio0.disabled="1" reduces the number of errors, but how can I get wireless to work? I tried OpenWrt-21.05 firmware and wireless worked fine there.

Unfortunately, none of the firmware labeled omega2-vX.X worked for me, and the firmware from the openwrt site does not have some of the necessary interfaces (like i2c) working for me

@Lazar-Demin Unfortunately, both ways you've suggested don't work to me, I don't have ethernet port, I use my custom shield, and I was trying to flash it via USB, but according to google I have old U-Boot 1.1.3 and Onion Omega2 UBoot Version: 4.3.0.3 and when I try to flash fw from the usb I get timeout error (found that it was solved in later versions)

I use the next steps to flash my omega2:

1. start command line tool
2. attach usb and copy openwrt-initramfs image to 0x81000000
3. erase linux
4. bootm 0x81000000

so when the device is running I connect to it via ssh and write omega2-0.3.3-b256 fw
5. cat omega2-v0.3.3-b256.bin | ssh root@192.168.1.1 mtd write - firmware

These steps are ok for 0.1.10-b160 and openwrt-22.05.02 firmwares, but not for the latests

openwrt is ok for general purposes (wifi connection, msc, etc), but it has a problems with interfaces, such as spi, i2c, gpio in general, so then omega2-0.1.10 is ok for that

I haven't used omega2 for years, but yesterday I decided to run it and update firmware. I had 0.1.10-b160 installed there and decided to sysupgrade with 0.3.3-b256 from here, after rebooting I got this stack trace

@Pavel-Metrokhin какая-то странная ситуация, вы открещиваетесь от дальнейшей поддержки девелоперской платы, выпущенной вашей компанией как раз для разработки в случае, если дефолтное состояние было нарушено (в моем случае - стер загрузчик, причем стер средствами нативного кода, зашитым при покупке самой платы), при этом проблема не возникла из неоткуда, а наблюдалась с самого начала получения мной платы (наша ранняя беседа в хелпдеске) - и, с учетом, частоты вашей поддержки я искал пути решения проблемы, которая не позволяла мне пользоваться полноценно покупкой. Ваш бутлоадер мне помог стартовать плату, но bootcmd по умолчанию настроен на tftp инициализацию, при покупке не было указано, что для работы платы требуется ваш док, я использую свои макеты, не вижу смысла покупать новую плату из-за того, что ваша компания не дает компетентной поддержки

@cas Sure I read this docs and didn't have troubles with it, but now, when I choose option 2 (Flash firmware from USB storage) I stuck with TIMEOUT issue
*ERROR: CTL:TIMEOUT X BBB_reset usb_control_msg: request: 0xFF, requesttype: 0x21 value 0x0 index 0x0 length 0x0 ERROR: CTL:TIMEOUT X

I found out that usb works fine if I reset USB bus, so that I enter in command line mode and execute the commands I wrote above.

If I put my firmware to the address 0x80000000, that I have LZMA error (I guess it's okay, because it seems to me uboot is there), so now I put omega2.bin to 0x80800000, and it's started booting, but returned me to the first screen (forgot to log it), of course, after rebooting my RAM is free, so how can I transfer omega2.bin to local storage to boot from firmware?

Here is my log file after bootm 0x80800000
https://pastebin.com/embed_js/vnpm2eb2

I can't install firmware from usb storage, always stuck. I entered in boot's console mode and executed this commands:
usb reset
fathead usb 0:1 0x80000000 omega2.bin // this copy my omega2 file into RAM starting with 0x80000000
boot 0x80000000

after this my omega is rebooting and I see the welcome screen again.

upd: according to log file
FAT: 7078054 Bytes read Omega2 # bootm 0x80000000 ##Booting image at 80000000 ...

how can I transfer omega2.bin file from usb to local storage of omega to boot from this one? I'm not able to use ethernet

Hi, I previously accidentally erased my flash with uboot, and don't have backups. So I decided to compile from this repo https://github.com/OnionIoT/omega2-bootloader new boot loader. Everything is ok, and I got uboot.bin

After that I upload this uboot.bin to my SPI flash (it's a SOIC8 W25Q128FV) via flashrom, but flashrom couldn't upload it successfully because the firmware size didn't match flash's size, so I truncated this file to get expected size and tried again. Flashrom flashed the uboot.bin file and verified it without errors. Next, I soldered it back to omega2 (I remembered where was the key) and now my console shows only this

I checked the soldered pins, everything is ok, maybe I missed something?
And one more question: I found my old logs, there was W25Q128BV recognised chip instead of W25Q128FV (this is marked on the chip)

Or may someone upload the backup of boot loader for omega2 (not plus)

@Douglas-Kryder for what? Pine is just simple dev board, ok, raspberry shows the same error, should I go to raspberry forum? I use flashrom, pine64 is connected by spi, and is used for communication only

upd: I resized uboot.bin up to required size and flashed it without errors, tomorrow I will solder it back to omega2 and test it
