Which version LSDK are you using now?

Please check whether the HS-400 mode can work.

Please check whether this patch has already been included in your source code.

I use openil 1.10. I have included this patch. When the following error occurs,

genirq: exiting task "irq/16-eDMA" (110) is an active IRQ thread (irq 16)

Then it will appear： mmc0: Timeout waiting for hardware cmd interrupt
