Change UART RX pinout on booting

On booting, UART1 is configured to P0_4 (TX1) and P0_5 (RX1) by default. Looking at smartsnippet, seems like I can also use P0_0 + P0_1, P0_2 + P0_3, or P0_6 + P0_7 pair. How could I assign different GPIOs to UART1? Do I need to run extra code?

Could I use other GPIO pins (e.g. P1_2, P1_3 or whatever) for UART1?

我可以用FTDI UART2 FLASH在总结吗mming?

Thanks
Hao

Hi jet_hao,

Hi jet_hao,

The primary bootloader scans specific pins with various interfaces in order to boot, please check the AN-B-001 document in order to check the booting procedure.

For programming the flash you will have to use Smart Snippets and you can choose between UART and JTAG interface you can change the pins for the location of the flash through the board setup tab in the SPI flash pin configuration section and you can use an FTDI.

Thanks MT_dialog
