CC2340R5: CC2340R5

HI,

The Serial Boot Loader allows to use an SPI interface to program the CC2340R5 device. Please refer to the CC23xx SimpleLink Wireless MCU Technical Reference Manual chapter §8.

In addition, we have published a tool to showcase how to use the CC2340R5 Serial Bootloader: https://github.com/TexasInstruments/ble_examples/tree/simplelink_low_power_f3_sdk-7.20/tools/TI_CC2340_Linux_SBL

As you will see, the tool is written to use UART as transport layer. It should be straight forward to modify the tool to use SPI instead.

I hope this will help,

Best regards,
