Original question:

CC2340R5: CC2340 Production Programming

CC2340R5: CC2340R5 Production Programming using UART

Tibor Szenti
Prodigy 10 points
Part Number: CC2340R5
Other Parts Discussed in Thread: UNIFLASH, SYSCONFIG

Tool/software:

The final design of the board I’m working on with the CC2340R5 chip will not expose the SWD interface; it will only provide UART via a USB-to-UART converter. UniFlash does not appear to support this configuration. How, then, can the CC2340R5 be programmed using UART and the ROM Bootloader?

    Hi Tibor,

    Here is a link to the TI_CC2340_Linux_SBL tool.  You can use this tool directly or as inspiration for your own host solution.  Make sure that your Sysconfig -> Device Configurations -> Boot Configuration retains the Default FCFG bootloader or enables the Bootloader in the CCFG settings.
