Onion Omega2+ bootloader

[Gnichi Mohamed]

Hello,
I would like to ask if there is anyway to flash a new bootloader in the onion omega2+ after i installed the last version.
I want to change uboot and kernel console to UART2.
TFTP doesn't seem to work
There is no Loadb in the new bootloader firmware
Does a sysupgrade image contain u-boot?

Thank you

@Gnichi-Mohamed No, the sysupgrade image doesn't contain the bootloader.
You can update the bootloader using the Web Recovery tool, just make sure to select u-boot update in your browser: https://docs.onion.io/omega2-docs/Firmware-Flashing-Web-Recovery.html

The bootloader source code can be found here: https://github.com/OnionIoT/omega2-bootloader
