I entered successfully in the bootloader menu for months pressing [SPACE] in a serial terminal.
I’m sure the serial port works properly because I see the expected outputs from other modules.
Some weeks ago I modified some bootloader parameters based on my needs.
Following this KB I disabled the bootloader output. As expected, I don’t see anything on UART_A but I can enter the bootloader pressing [SPACE].
First issue: I can’t restore the original behavior if I set boot.silent to 0.
Second issue: In this scenario the VFxx Recovery mode doesn’t work (on Colibri Evaluation Board 3.2). I tried both “uboot over eboot” and “eboot over eboot”, but none of them worked.
How can I configure the bootloader to print information on UART_A again?
Some weeks ago I set my custom splashscreen image (fullscreen).
Third issue: It seems that after this configuration, I can’t enter the bootloader anymore (pressing [SPACE]).
The behavior seems similar to this one for iMX7 but I can’t use EasyInstaller (which worked in that case).
