      Above mentioned error am getting but its seen like soc related error.

      If am boot from emmc there is no error.

Thanks & Regards,

[igorpadykov]

for "imx/sdma/sdma-imx7d.bin failed with error -2" one can look at

https://community.nxp.com/t5/i-MX-Processors/Kernel-5-4-imx-6q-sdma-firmware-not-ready-SPI-transfer-...

Also one can try with latest L5.4.70_2.3.0
