"MMC: no card present" issue in u-boot and Kernel does not start
When I start SD boot with a custom board based on i.mx8mini, "MMC: no card present" issue in u-boot and Kernel does not start.
The environment in which it is implemented is as follows.
-----
yocto:imx-linux-kirkstone
Kernel: imx-5.15.52-2.1.0.xml
-----
We have confirmed the following:
Execute the following command in u-boot.
-----
u-boot=> mmc dev 0
MMC Device 0 not found
no mmc device at slot 0
u-boot=> mmc dev 1
MMC: no card present
u-boot=> mmc dev 2
switch to partitions #0, OK
mmc2(part 0) is current device
-----
mmc dev 1 is not recognized.
What should I check and fix?
Attached the "imx8mini_kirkston_uboot.log“ log when the problemed issue.
Best, Regars,

can you boot from demo images?
pls let me check your uboot environment by the "pirntenv"
how about setting mmcdev to 2 and mmcroot to "/dev/mmcblk2p2 rootwait rw"?
can the board boot up?
