ERROR: JLinkARM DLL reported an error

[Sorena]

Hi NordicSemi,

I am trying to program an Nrf52811 by using nrf52-dk in ubuntu and vsc.

I have actually programmed it several times and it worked until yesterday. However then I got this ERROR: JLinkARM DLL reported an error.

I have attached the log file here, but so far I found that some times when I restart the pc it can program the device for one time and then for the next times I get that error.

One time I even managed to re program it without restarting by reconnecting the usb cables and restarting the VSC but even this solution worked only one time. 

I have just updated my JLink driver to JLink_Linux_V794_x86_64 without any luck. If I run JLinkExe in terminal I can find NRF52 device and connect to it as JTAG.

I appreciate if you can help me in fixing it because I have been stuck there now

Thanks,

Sorena

Hi, 

I am using S1 module from siliconwitchery https://www.digikey.com/en/products/detail/silicon-witchery/S1-POPOUT-BOARD/15926536

So, it is a standard board and I changed it with another one without luck. While my colleague can program both on another PC.

The log is being generated with this command in the make file:

# "make flash" will use the nrfjprog tool to flash the nRF chip using a JLink
flash: $(PROJECT_NAME)
nrfjprog -f nrf52 --program $(OUTPUT_DIRECTORY)/$(PROJECT_NAME).hex --sectorerase -r --log

note: It started to work yesterday afternon without I change anything and I can program it now! However, I scare that it happens again.

regards,

Sorena

Ok, if it starts to fail again, can you try to use nrftools 10.23.2 with JLink 7.88j?
