We have built a custom board using Rev 2.0 of the LS1020. We would like to use the LPUART2 port as the U-boot console. We used the LS1021A-IOT board as the reference board in our design.
How should we modify the U-boot configuration in order to use the LPUART2 port as the console?
We modified the RCW : UART_EXT = 001.
We added the line #define CONFIG_LPUART in the include/configs/ls1021aiot.h file.
But we still do not receive any response from U-boot application.
