Howdy - still struggling to unlock bootloader (or at least I think that’s what’s happening) on the router.
I’ve tried UART on pi, usb-ttl no brand adpater, adafruit usb uart adapter, tried across pi, ubuntu and windows boxes with no joy, still getting the dreaded ERROR: Timeout waiting for ACK/NACK after 'Synch (0x55 0x55)'.
Can i just triple check steps?
- Plug in usb - uart device without router attached
- Do not plug in power supply to micro usb
- Hold down bsl button
- Plug in jumpers to header on router
- Keep holding down bsl button for 10
- Release and launch command, e.g.
python ./cc2538-bsl.py -p COM5 -b 9600 -ewv .\CC1352P2_CC2652P_launchpad_router_20210128.hex
No specific baud settings required, default 50000 okay?
Thanks again.
