[2020-Dec-03 16:46:48] [debug] [nRF520x0] - nRF family DLL closed
I have designed a custom board with the nRF52840 following the examples from the dev kit, dongle, and datasheet (circuit config 5). The board is similar to the dongle but also has an option to run from a coin cell. However, I am unable to program the board in any configuration. This is my first time diving into Nordic chips, so I am not entirely sure where to investigate next.
I am using the nRF52840-DK to program the new board. When the device is plugged into 5V, VDD_nRF is measured at 3V. (this is expected - I have an LDO which dros down to 3.3V, then a schottky diode).
When I try to program in Segger Embedded Studio (Release 5.10b), I get the error "Failed to connect to target. No idcode detected. Please check connection and Target Interface Type."
When I try this command: nrfjprog --recover -f NRF52 --log
I get the following error (log.log file attached):
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.
When connecting to USB, the device does mount as a USB serial port. If I use the nRF Connect programmer, it is able to identify the device serial number and the chip type:
However, when I try to program a hex file, it asks me to select the SoftDevice required by the application firmware. If I select any option, it reports a DFU targer error "The array of supported SoftDevices for the update does not contain the FWID of the current SoftDevice". (this is despite the fact that I am trying to write a blinky firmware image.
The above error may be due to the source of my nRF52840 IC. Due to a shortage of parts at many distributors in the US (won't be able to get any new chips until January), my source of the nRF52840 IC is removing one from an nRF52840 dongle, cleaning off all the solder, applying new paste, and hot air solder to my new board. I have re-worked the IC several times to verify that it is fully connected - I believe since it is able to mount over USB that it is properly soldered.
I have attached the key portions of my schematic, and I'm not really sure what to try next! Am I missing something silly?
Thanks,
Daniel
