Switch to linux-imx/linux-fslc-imx for DSI

[dpog]

I'm currently using linux-fslc on our custom board based on the i.MX8M mini eval kit, running the community kernel linux-fslc 6.1. As the DSI-Interface is not supported in the mainline and linux-fslc kernels, we wanted to switch to the linux-imx or linux-fslc-imx variants. After compiling just fine and building the image, the board hangs right at the entrypoint of the kernel, the uboot shows the handoff message "Starting kernel ...", but the kernel is not responding.

I already tried to set the earlycon to ec_imx6q,0x30880000,115200 (we are using UART2 as console), but so far no output.

Any suggestions what might be different so the nxp-supported kernel would not start?

Sorry there is no i.MX8MM MIPI DSI support in mainline yet.

Yes, I already wrote that. My problem isn't that there is no support in the mainline, my problem is that neither the linux-imx nor the linux-fslc-imx kernels (which both support DSI on the i.MX8MM) would start.
