Hi anyone:

         I'm porting android8.1.3 to imx8mq. I success in bootup from emmc, but failed to bootup from ecspi(ecspi1 connected with a nor flash).

         The uboot is the same as the uboot bootup in emmc, and have burn to position of 33K.

         And I have success to boot up with the same "nor flash" in imx6.

         Any suggestion ?

Best Regards.

Hi YaQiang

i.MX8M supports boot from NAND flash, SD/MMC as described in

sect.6.1System Boot i.MX8MDQ Reference Manual (rev.0  1/2018)
https://www.nxp.com/docs/en/reference-manual/IMX8MDQLQRM.pdf

There is no option for boot from ecspi.

Best regards
