Dear sir,
I want to use GPIF 32bit bus width in my design and UART for debug, spi flash for booting. but it seems that SPI flash memory signals can not be mapped because they are shared with UART_RX and UART_TX when 32bit gpif is used.
How to deal with this case: 32bit width gpif,uart debug and spi flash booting are working at the same time?

SPI interface will be just used for booting during which the UART will not be used. Once the application firmware is booted up, you can configure the IOMatrix for 32 bit GPIF and UART. So the same SPI lines will be used for UART now after booting.
