Flashing Thingy:91 nrf9160 using nrfConnect Programmer works, but ninja flash and west flash fails. Also how do I get gdb to flash when connecting to JLink gdbserver

arfwid

Since nrfConnect Programmer, ninja flash/west flash ALL use nrfjprog behind the scenes, I wish I could find out _exactly_ which nrfjprog commands the nrfConnect Programmer is using!

I am trying to flash the nrf/applications/asset_tracker built for nrf9160_pca20035ns. cmake and ninja build works perfectly, but ninja flash fails. Using the nrfConnect Programmer to flash merged.hex works perfectly. I am on master branch on Ubuntu Linux 18.04.

1. How can I get ninja flash to work?

2. How can I get gdb-arm-none-eabi to flash as part of the init when I connect to the JLink gdbserver? So I get the latest version flashed on there when I connect to jlink gdbserver?

This is my gdb init, "load" appears not to be working (stolen from  https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf52-debugging-with-qtcreator-on-windows ) :

set remote hardware-breakpoint-limit 6
set remote hardware-watchpoint-limit 4

monitor semihosting enable

load

monitor reset 0

Step 1 would be more convenient than using the gui programmer. Step 2 would be more convenient than step 1.

Here is the output of ninja flash:

    Hi,

     

    1. How can I get ninja flash to work?

    On the thingy:91, there's no dedicated reset line, so try to erase the chip first:

    nrfjprog -e && ninja flash

     Could you see if this works?

     

    2. How can I get gdb-arm-none-eabi to flash as part of the init when I connect to the JLink gdbserver? So I get the latest version flashed on there when I connect to jlink gdbserver?

    I do not have much experience with qtcreator, but here's how I start up a debug session.

    Try starting the server with:

    JLinkGDBServer -if SWD -device nrf9160

     Then enter debug mode, with the following:

    arm-none-eabi-gdb /path/to/.elf
target remote localhost:2331
load
mon reset
c

     

    Kind regards,

    Håkon

    The GDB stuff works like a charm!

    But the flashing fails, "nrfjprog -e && ninja flash" perhaps not surprisingly produces the same output and failure as before when I just did "ninja flash".

    Aha, the nrfjprog -e runs succesfully, it's the subsequent "ninja flash" that fails to flash the merged.hex

    I am attaching the last couple of lines of log.log generated by "nrfjprog --log --program /home/arvid/ncs/nrf/applications/asset_tracker/build-20035ns/zephyr/merged.hex -f NRF91 --snr 50123109 --sectorerase"

    The whole log.log file was too big to attach

    On closer inspection, "load" from gdb does not work - I changed the code, rebuilt, and the "load" command in my gdb init was not effective. The old binary was being debugged using the new elf file, which was evident because new printouts I had added were not being printed, and stepping through the code produced unexpected results (i.e. gdb "n" not going to next line, but completely different source code). I had to go to the nRF Connect - Programmer and flash the new merged.hex. Restarted gdb server, reattached gdb, Then the new binary was being debugged using the new elf file, because "n" was again working as expected, and the new printouts I added show up.

    Hi,

     

    I was able to reproduce the behavior you are seeing, especially when programming larger binaries.

    Could you try this:

    1. Call "nrfjprog -e" to erase the nRF9160 chip.

    2. Power cycle the thingy:91

    3. Program it either in gdb/IDE or using "nrfjprog --program <hex> --verify -f nrf91"

     

    And see if you are able to successfully program? This worked on my end.

    I am very sorry for this issue, and I can assure you that we are working on fixing this inconvenience.

     

    Kind regards,

    Håkon

    Thank you Håkon, I was talking to a colleague at lunch and he told me the exact same steps: you need to erase and power cycle it before flashing =D
