Hi
Now I test uart2 with sdma1, but when I write character to "dev/ttymxc1" (it is for uart2 device), It report the blew error:
Could anyone know this error, and how to fix it ?

Hi Hongxing
what bsp used in the case, suggest to try ones from
source.codeaurora.org/external/imx/linux-imx repository
linux-imx - i.MX Linux kernel
for uart2 one can check below dts (it can be used by M4)
fsl-imx8mq.dtsi\freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel
fsl-imx8mq-evk-root.dts\freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel
Best regards
igor

HI igor
If I test the uart2 without sdma1, it is ok.
So the uart2 is ok, maybe the sdma1 is not ok.
So Could you give some supply if is the sdma1 is not ok?
