SWD programmer Vs BLE400 #21

Closed minkione closed 5 years ago

minkione commented 5 years ago

Hi, I was planning to play with a waveshare BLE4000 board and the walkthrough to the wiki. Do you have some external link about programming the board with the SWD Programmer?

So far I have found this resource, but is not clear how to push the new firmware... https://rlangoy.github.io/OpenOCD_MBED_FRONTEND/HWExample.htm

This is probably an issue for the btlejack-firmware, but I am also struggling to get this flashed into the BLE400 using RPi/OpenOCD. I seem to have successfully attached the RPi to the BLE400 using SWD, as described in the link you provided, and I have also established a working OpenOCD session, where I issue the following commands:

init
reset
halt
nrf51 mass_erase
program /<path-to-the-firmware>/ble400.hex verify
reset
shutdown

Everything looks ok in the end, apart from a not so bright lit LED2. Anyhow, I then run btlejack -d /dev/ttyUSB0 -s and stays there forever. No errors, no nothing. Is this a proper way to flash the firmware to the BLE400 or there is something missing? Also, is there any way to verify that the flashing was successful?

Just an update to this. I ended up recompiling the latest firmware for BLE400 and then flashed it, following the exact aforementioned steps and now it is working fine. @minkione Make sure you have the correct swd pins defined in interface/raspberrypi2-native.cfg for openocd to see the core51822/ble400. I had to add this line: bcm2835gpio_swd_nums 25 24

Thank you for this information. It may be interesting to add it to Btlejack's documentation.

@virtualabs Thank you for this epic tool :)

@bogiton Can you please give some tips on how to recompile the BLE400 firmware? I am a complete beginner and would like to try BtleJack with BLE400. Unfortunately I get a message after starting the tool that I have to update the firmware.

Thank you in advance!
