I am trying to boot linux from micro-SD card in i.MX audio board with IMX8MNano as SOM. In Nano development board, it can boot linux from SD card. However, in the audio board, though it can load u-boot from SD card, u-boot failed to load linux with following error messages:
MMC: no card present
flash target is MMC:1
MMC: no card present
MMC card init failed!
MMC: no card present
** Block device MMC 1 not supported
Net:

hi Igor,
thanks for your kind reply.
I can boot from sd-card in the nano development board.
I'm now planning to test audio in the audio dev kit. The nano SOM is installed as the interposer board.
It can load u-boot when to boot from sd-card in the audio board, but u-boot failed to detect sd-card.
Do I need another device tree to run nano in the audio board?
best,
Michael
Hi Michael
reason may be wrong root=/dev/mmcblkXpY parameter described in
Table 11. Common kernel boot parameters i.MX Linux Release Notes
In audio board there is no emmc, one can try to boot without audio board.
Use Demo Image from link
Best regards
igor
