hi,

microsd card is not working, insertion of the card detects but ends with below dmesg log

root@linaro-gnome:~# dmesg | grep sdhci
[ 2.312945] sdhci: Secure Digital Host Controller Interface driver

There is no card detection in the log you shared, this is the initialization of the sdhci controller. When inserting a sdcard you should see something like:

mmc0: new high speed SDHC card at address 0001
mmcblk0: mmc0:0001 ASTC 29.1 GiB
...

So maybe try dmesg | grep -e sdhci -e mmc instead
