Other Parts Discussed in Thread: CC2538
Hello,
As part of our production programming process, we want to load firmware to the CC2651 using the UART bootloader (we don't want to connect to JTAG). We have another product that uses CC2538, and we can force bootloader entry using the backdoor, because the backdoor on that part is enabled by default on a specific GPIO. However, in CC2651 the backdoor is disabled by default.
Question:
In the TRM it states "To enter the ROM bootloader even when a valid image is in the flash, a bootloader backdoor is implemented.". However, it does not specifically state that the bootloader IS entered when there IS NOT a valid image in flash. What happens when there is no valid image in flash (fresh device from factory)?
Thanks,
Andy
