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:
