ESPI loop back test in iMX8MM EVK

[gsbalajikrishnan]

Hello,

I am using iMX8MM EVK for project.

I would like to do hardware ESPI loop back test in iMX8MM board. However, I could be able to build u-boot image and boot successfully.

So, I want to know how to build image to test ESPI loop back and where can i find this test code.

Kindly let me know if some steps are available.

Hi @gsbalajikrishnan,

I hope you are doing well.

One can use the test code mentioned below for the ECSPI loopback test.

imx-test/test/mxc_spi_test/

/test/mxc_spi_test/readme.txt

Please refer to 11.3.1 Enhanced Configurable Serial Peripheral Interface (ECSPI) in i.MX Linux Reference Manual

Thanks & Regards,
