Dear NXP community,

I am developing a custom board based on the Coral System-on-Module.

Since I want to show Splash Screen on uboot , I am trying to enable mxc_spi.c first.
There is get an error message "No cs-gpios property" when call the mxc_spi_probe api.

Is mxc_spi.c support imx8mq(Coral System-on-Module) ? or any command?

the attached is our dts & code.

Hi Kuda

 

seems some third party boards support uboot "cs-gpios" ecspi property as in below example:

https://github.com/boundarydevices/u-boot-imx6/blob/boundary-v2020.10/arch/arm/dts/imx8mq-nitrogen8m...

 

Best regards
