What is the stable firmware for omega2?

Ilya Mordasov

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

BusyBox v1.28.3 () built-in shell (ash)

Meanwhile I successfully updated with openwrt-21.05.02 downloaded from here

Could you suggest me the right way how to get the latest onion's firmware?

@Ilya-Mordasov 0.3.3-b256 is the latest available firmware and should work.

Can you please try flashing the same firmware using the bootloader + web recovery method or the bootloader + usb method, and letting us know how it goes?

Ilya Mordasov

@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:

start command line tool
attach usb and copy openwrt-initramfs image to 0x81000000
erase linux
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
