OSD32MP1-RED MMC0 boot

[EmmaKa]

we are working on a new board based on the OSD32MP1-RED with minor changes LEDs buttons etc..

When I create an SD card with from the file “osd32mp1-red-trusted-openstlinux-sdcard-v1_2.raw” the system boots.

If I create an SD card with the “osd32mp1-red-trusted-openstlinux-sdcard-v3.0.raw” image, I get the following message:

I Don’t know anymore – what could be the reason?

EmmaKa,

 

Please take a look at your circuit for SD card Detect pin. Card detect pin was not polled in v1.2 image. In v3 image, card detect pin is defined here: https://github.com/octavosystems/meta-octavo-osd32mp1/blob/dunfell/recipes-bsp/u-boot/files/0008-Add-OSD32MP1-RED-Device-tree-support.patch#L1526. GPIOE 7 must be pulled LOW or you can disable card detection in u-boot device tree.

See README for https://github.com/octavosystems/meta-octavo-osd32mp1.

Best,

Neeraj
