Hello, I’m working on a pcb using the nrf52832, and the OS (Zephyr) crashes whenever I try to use bluetooth. This is due to some error implying timing issues. I have the dev board, and measuring the crystals on there gives wildly different frequencies than on my pcb. See below:
My theory is that this is caused by poor pcb design. I started with the reference design and tried to build around it. Maybe not enough vias leading to parasitic capacitance skewing the frequency too much? Please let me know if you have ideas.
That’s embarrassing. I ran it for a previous version but had to transition to kicad and didn’t because there were many false positives. I didn’t think the flood fill would be different. Thanks for spotting this
I see that you cross-posted in EEVblog and somebody pointed out that you have unconnected pads which DRC would have caught. Better fix those issues before you worry about the discrepancies.
