Hello Peng, Teresa,
I am just trying to get linux-stable 5.10.y kernel with current mainline U-Boot on the pyhcore imx8mp board up and running, and fail detecting sd card on usdhc2 in linux.
With U-Boot 2021.01 *same* kernel image/dts detects fine the sd card on usdhc2. So I have no idea, why kernel is here dependent on U-Boot setup! Which is also a bug I think ...
@Peng: Now started a small git bisect in U-Boot tree and your commit
cf8842bc29 - arm: dts: imx8mp: sync dts from Linux Kernel
poped up... with the commit before:
374866a724 - imx8m: clock: add type of set_clk_eqos
the phycore imx8mp board boots fine linux kernel and kernel detects sd card...
Attention: The phytec board support came later into u-boot tree with commit:
c661c511e9 - board: phytec: imx8mp: Add PHYTEC phyCORE-i.MX8MP support
So the board support patch was pending on the list and not tested with your patches I think...
Any ideas, what could be the problem?
Thanks!
bye, Heiko
