Hi.
The CC2340R5 does support a backdoor pin to trigger the bootloader. By default, this pin is set to DIO21.

One mre thing, which UART pin support this? all of UART rx/tx pin?? like in cc2640R2F, only dio0/1 support it.
Hi,
The bootloader UART and SPI pins are fixed and cannot be changed. I will need to look in to which pins these map to and get back to you.

Hi,
The pins used will depend on the PG version of your IC as well as the package. For a PG2.0 LaunchPad, the RX and TX pins will be 22 and 20.
