How are you using this pynrfjprog, meaning, what instructions are you using? When does it fail? Can you give a little bit more detail?
Thanks

7 years ago Hi David,
We are using the script below, invoked as ./nrf_programmer.py ${SOFTDEVICE_HEX} ${PROJECT_NAME}.hex. Most of the time this works, but occasionally it fails with this error. What additional details would it be helpful for us to provide?

program_hexfiles(nrf, args.hex_files)
nrf.sys_reset()

nrf.close()
Based on the stacktrace, it appears that the crash occurs within the call to connect_to_emu_with_snr.

7 years ago It looks like the error occurs when calling JLINKARM_OpenEx in the Segger jlink DLL. We suspect that this might be because the dll is not yet closed.
Do you catch the exception in the try-exception block in connect_to_nordic, or does it leak out? Our guess is that this might happen if you try to run the script too often, if garbage collection does not pick up the dll before it is opened again, although this is unlikely. Or, this would happen if you tried running several instances of this script simultaneously. For this use case, you have to use multiapi.

commented
7 years ago Do you run this script multiple times within the same python environment?
simtind
commented
7 years ago If you run it multiple times, you should not open/close the dll every time, as we suspect there is a small memory leak in the segger dll. The solution is either: Do not open/close the dll on each iteration, rather, pass an instance to the script. This way the leak happens once, and is picked up at the end of your python script. or Use the multiapi, by importing the api as "from pynrfjprog import MultiAPI as API" No further edit of your code should be necessary, but this will slow down your script slightly. This will open the API in a separate thread that gets terminated when the multiapi is deleted. Any leaked memory is then collected from the thread by the OS.

7 years ago Thank you for the detailed explanation!
As a test, I tried running our script in a loop (to see if it would crash after many iterations). Using this stress test, I can reproduce the error.
I switched out API for MultiAPI.

#!/usr/bin/env python
from pynrfjprog import API
for i in xrange(1000):
print i
nrf = API.API('NRF52')
nrf.open()
nrf.connect_to_emu_without_snr()
nrf.close()
I've also tried this test case with MultiAPI. Sometimes I get the same EXC_BAD_INSTRUCTION error, but more often I get the unrelated error:

7 years ago I have reproduced the issue. I have isolated the issue in Seggers JLinkARM library, and therefore reported the issue to them. It is most likely a resource freeing issue. If a 100ms delay is added after nrf.close() call (in your reproduction script) the issue seems to disappear.
I will inform of the response from Segger as soon as I receive it.

7 years ago Segger has released on Friday V6.12e that according to them fixes the issue. I have had no time to test it, but you could try yourself. Please close the issue if the new Segger release solves your problem.

7 years ago Confirmed that this fixed the issue. Thank you very much for your help!
Versions: pynrfjprog==9.0.0, 9.2.1
Occasionally, when flashing our board, pynrfjprog crashes with the error below. We're not really sure how to debug this issue, and may have to consider switching back to JLinkExe :( Do you have any suggestions on how to proceed here? Thank you for your help!
