Re: [PATCH v2 0/2] board: sophgo: add support for Milk-V Duo 256M

Hi Hiago,

Thank you for the patches.

From your cover letter I understood that SD card is supported.
However whatever I try, I always get the following error:

    milkv_duo_256m# mmc rescan
    Card did not respond to voltage select! : -110


I tried 2 different SD cards and got the same result.

Am I doing something wrong, or is there something else I need to configure?
