#299 OpenOCD SAMD21 programming from RPI Error Flash write discontinued / NVM programming error
I am trying to use OpenOCD + RPi to program an ATSAMD21J18A via SWD. I have a connection, can see flash info but programming fails with a Flash write discontinued / NVM programming error.
I have a feeling it has something to do with Erase or reset.
This is the error point:
** Programming Started **

SAMD: NVM programming error
Failed to erase row containing 00000200

I've used telnet localhost 4444 to feed line by line, but I get the same error when I try to program. Tried changing adapter speed/delay, tried flash write_image, flash info 0 shows no protection.
How critical is the reset pin connection for this set-up. I may have an issue there.
I suspect the command -c "at91samd bootloader 0" does not work as expected and flash stays locked.
You have first issue "init" to close up OpenOCD initialization, then prepare the device for programming by "reset init". The script "program" calls both "init" and "reset init", but it is too late for "at91samd bootloader 0".
Try this:
openocd -f interface/raspberrypi2-native.cfg \
-c "transport select swd" \
-f target/at91samdXX.cfg \
-c "init;reset init;at91samd bootloader 0" \
-c "flash write_image erase openocd_hex/123456.hex"
and if it works, add "verify_image openocd_hex/123456.hex" and setting bootloader protection.
If the problem persists, please run with -d and upload full debug log to some paste bin service.
Thank you Tom,
I should have thought to dig into the debug output.
I tried the code as you mentioned, but have the same result:

at91samd bootloader command help reads:
..."Changes are stored immediately but take affect after the MCU is reset"
So you need add one more "reset init" before "flash write_image..."
BTW: I'm sure your original commands resulted in error
Error: The 'at91samd bootloader' command must be used after 'init'
Next time please copy whole OpenOCD output!
Added reset init but hit similar error.

Both logs shows a parity error at SWD level.
The problem is most probably in the wiring (too long wires, crosstalks between SWCLK and SWDIO, poor grounding, EMI etc...)
I will check.
Does the reset pin need to be connected?

thank you Tom, I had success.
The main issue was that this ATSAMD21J18A required a reduced adapter speed.
I did not use the reset pin or require "at91samd bootloader 0" on this application.
This script works for me using a R-P1 3B+ as the programming adapter:
openocd -f interface/raspberrypi2-native.cfg \
-c "transport select swd" \
-f target/at91samdXX.cfg \
-c "adapter speed 200" \
-c "program 123456.hex verify" \
-c "shutdown"
