请问如何配置 I.mx8 mini 的早期 串口
bootargs = "console=ttymxc1,115200 earlycon=ec_imx6q,0x30890000,115200";
请问 ec_imx6q , 是 i.mx8m mini 的早期 串口吗
As the i.MX8MM use the same console as the i.MX6Q so here the earlycon=ec_imx6q,

But for i.MX8QXP and 7ulp do not use the same console, so they do not use this driver, you can see it here

You can see this
