I'm trying to use SDP on the imx8mq-evk but it doesn't look like it's
enabled
there. Do you have patches to enable SDP on the imx8mq-evk , even if
they
aren't ready to go upstream ?
You could try downstream code,
https://source.codeaurora.org/external/imx/uboot-imx/
branch: imx_v2019.04_4.19.35_1.0.0
I already have SDP working with the vendor u-boot. I'm trying to switch
to mainline u-boot so I'm looking for mainline patches.
Thanks
Angus
