I am working on a custom board with multiple nRF chips, one of which is a nRF9160. While developing the BSP for the 9160, I accidentally swapped the MOSI MISO pins on a SPI interface and ran some test code. Now the chip is unresponsive. I have tried recovering the chip with `nrfjprog --family NRF91 --recover --log`, but I get the following error.
Recovering device. This operation might take 30s. [error] [ Client] - Encountered error -21: Command recover executed for 120 milliseconds with result -21 [error] [ Worker] - Encountered unexpected debug port ID 0, expected 6 ERROR: Recover failed. Please make sure that the correct device family is given ERROR: and try again.

[error] [ Worker] - An unknown error. 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. NOTE: For additional output, try running again with logging enabled (--log). NOTE: Any generated log error messages will be displayed.
The log from above is the following

Is there anything else I can try to recover the chip? Or, could I have killed it, and if so, how can I confirm?
SOLUTION: None. The issue turned out to be a low battery pack. It first presented itself after running some test code, which is why I thought I had damaged the chip. The battery was strong enough to power the nrf52840 chip on the board but not the nrf9160.
