您好!我想要将 i.MX8QM 中的 ATF 的串口由 UART0 改为 UART4 ,我将 imx8qm_bl31_setup.c 文件中的串口基地址,串口和引脚等参数进行了修改,但是 UART4 并没有 log 输出。我是否还需要在其他地方作修改呢?能不能给我提供帮助,谢谢!
Hi Winters
also one can look at uart settings in scfw ..platform/board/mx8qm_mek/board.c
and sect.3.4 Compiling the Code System Controller Firmware Porting Guide, sc_fw_port.pdf
Best regards
igor
