CC2640R2F: OTA for CC2640R2F

Part Number: CC2640R2F

Tool/software:

Hi there Good Morning,

I want to perform OTA for chip CC2640R2F, and we are using STM32L chip where it will take the BLE Bin file and verification is done in STM scratchpad area if verification is passed then it should be sent to TI through UART in chunks. Here we are using serial bootloader which is placed at 0x00000000 address which is responsible for OTA process if DEV_MODE is 0 then it will go Handle Packets where it is responsible for OTA receive commands. Like I need help from you like how from STM we can send the verified bin file in chunks through UART to TI and how it will be seating at 0x00003000 address.

Thanks 

Navya

    Hi Navya,

    I would be happy to help here! If you are using the Serial Bootloader to flash the device, then using the COMMAND_DOWNLOAD (see chapter 8 of the TRM) you can specify which address you want to start flashing so you may set 0x00003000 as the start address.

    Afterwards, you use the COMMAND_SEND_DATA to actually send the data.

    Best Regards,

    Jan
