MT35XU02G cannot be used on i.MX8qxp

[george_wang]

Hello

I am using i.MX8qxp and 4.14.98 BSP

when I use mt35xu512aba spi-nor flash, everything is fine

I can get JEDEC id through command "sf probe"

But when I use MT35XU02GCBA2G12-0AAT, there is a problem

I always get the information below

SF: unrecognized JEDEC id bytes: 00, 00, 00

How can I fix this problem

Thanks

Hi George

problem may be that some SPI NORs only supports octal mode even for the ReadID command. 

One can try to debug it in spi_nor_read_reg() function in driver and and make it work in octal mode:

spi-nor-core.c\spi\mtd\drivers - uboot-imx - i.MX U-Boot 

Best regards
igor
