I have ordered DWM1001C few days ago. I made a custom board using the pcb files of DWM1001-DEV provided by Decawave as DWM1001-DEV is not in stock. The custom board is exactly same as the DWM1001-DEV board but it doesn’t have the on-board J-Link. I am using the external debugger availabe on nrf52840DK dev board. I know that DWM1001C is delivered blank and I have followed the Firmware User guide(section 3.3) and flashed the module with factory image(DWM1001_PANS_R2.0.hex) using J-Flash Lite. The LEDs on the Boards were active as mentioned in the guide.
The problem I am facing is that after flashing I am not able to use the module for further debugging. I get error that “Failed to detect target” both in J-Flash Lite and SEGGER Embedded Studio. Its the same case with every other module I tried. The flashing works for the very first time and then I am not able to connect.
I even tried the approach where we make changes to dwm-simple and create a new image file combining the softdevice,bootloader, FW1 and customised FW2 and flash with dwm1001_dwm-simple.hex
Can anyone explain why this is happening? Am I doing it the wrong way or is there any problem with the Debugger(i.e. nrf52840 DK)
