CC2650 ROM bootloader reset

Lenio Cacula
Genius 16700 points

How can we re-initiate the ROM bootload sequence in the device before it has finished? Is a hardware reset the only option or should we use HCI_EXT_ResetSystemCmd(HCI_EXT_RESET_SYSTEM_HARD); or HAL_SYSTEM_RESET();? Is there an option to re-initiate the bootloader without resetting the device at all?

Thank you!

    Hi Lenio,

    When the MCU is in the ROM bootloader (RBL) state, you will need to reset the RBL via a HW reset. The HCI commands are only valid when the MCU is running the BLE Stack from internal flash memory.

    Note that after you have completed the download sequence & programmed the internal flash memory, you can issue a RBL COMMAND_RESET to reset the MCU to begin executing the new SW.

    Best wishes
