Hi Team,

I want to flash target hex file from through UART. I cant use ROM bootloader because my boards are not using default pins. So i have to write my own FLASH bootloader with reconfigured UART pins. Could you please help me to setup this and writing a new bootloader. My end use case is firmware upgradation in custom board

Hi Paul,

You can find a flash implementation of the ROM bootloader here: github.com/.../ble_examples-2.2

Cheers,
Fredrik

Okay. Thanks for your reply. I will check and let you know. Do I need to integrate that serial bootloader folder in util to my project for cc2640??

Hi,
Now our board reworked with default pins of cc2640r2frsm ...dio_1 and dio_2 for UART pins. Now I need a serial bootloader for loading our hex file from board. Can you please share that.

Hi Paul,

If you are using the correct pins for the ROM bootloader you can simply use that. Refer to the Technical Reference Manual for details:www.ti.com/lit/pdf/swcu117
