solved, first issue due to xc2 shorted to 3v0, second issue due to bad ble configs. Thanks.

I'm pretty new with zephyr and nrf52, could it be possible that the chip's missing some stack that I can maybe flash on?

EDIT: I guess I would first like to know what these errors mean, like if it points to any areas of the hardware that is an issue, like maybe unpowered bus or modem?

got another error message, it does appear there is a hardware issue, just not sure whether it's specific to the NRF52832 or an assembly issue:

Yes this project is on v1.6.0

We haven't done any radio testing, but I have tested with one of the examples, peripheral_uart, and got the same issue:

How would I run the radio test and what should I look for?

Hello,

From the path it may seem as you are using a very old nRF Connect SDK (latest is v2.5.1), can you just confirm you are indeed using v1.6.0 before we look into this? Have you run any radio test and similar just to confirm that the board is working?
