I have a custom board based on ls1021a twr that has spi flash connected to spi2 and uart2 as a serial port

While trying to modify rcw configuration I found the following:

and uart base as

So If I configure uart_ext for spi2 then I won't be able to configure uart_base for uart_2, is there any way I can use spi2 and uart2?

There is no possibility to use UART2 and SPI2. See the Table 3-3 in the LS1021a Reference Manual:

Use LPUART instead of UART2.

Have a great day,
