Dear U-Boot Community,
I am working on a project involving the Amlogic A113X SoC and have
encountered an issue with U-Boot during the boot process over UART. While I
am able to connect via UART and observe the boot log, the system does not
allow any interaction or command input. It seems that the manufacturer may
have restricted this access, potentially violating the GNU GPL license.
Here are the details:
- *SoC:* Amlogic A113X
- *Bootloader:* U-Boot 2015.01 (Jan 13 2023 - 10:30:19)
- *Issue:* The device does not respond to input during the boot process
over UART (no response to Ctrl+C, Enter, etc.)
- *UART Log:*

I understand that U-Boot has been modified by the manufacturer, which
complicates the situation. I am seeking advice on the following:
- Are there any known methods or workarounds to regain control over the
U-Boot environment in such scenarios?
- Are there any specific forums or community resources where I might
find additional help or similar cases?
Any guidance or suggestions would be greatly appreciated. Thank you in
advance for your assistance!
Best regards,
Mike
