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
