U-boot prompt console #9

Open annadm99 opened 8 months ago

annadm99 commented 8 months ago

Hi, I've encountered an issue while attempting to make changes in U-Boot. I found that I cannot save the environment variables because the command saveenv is not recognized. Would it be possible for future releases to include U-Boot builds with the saveenv command enabled by default? This would be helpful so that users like me don't have to recompile U-Boot to enable this feature. Release: radxa-cm3-io_debian_bullseye_kde_b27

We will consider this, but it will take a while, since this feature should work on all supported products in all supported boot media, before we can release it.

Ok, thank you. Can you help me activate saveenv on the CM3? My intention was to save it in the flash memory, but I'm unable to find the partition table for the CM3, and I don't know what ENV_ADDR should be set to.

Currently it is not supported, so there is no "activation". Development time will be needed to bring this feature online.

I understand. Thanks for the update. I managed to find the solution on my own; I enabled saveenv and successfully saved the environment variables to MMC.
