Hi KV,

Could you please tell me how you did to solve the problem? I have exactly the same problem like you.

Thanks in advance.

After commenting out the uart_init this issue seems to go away. I suspect that there are conflicts in pin assignments between the custom board and the dev. kit. For now, this issue can be closed.

Also the 52840 is wlcsp which makes it impossible to inspect soldering. If you have access to X-ray equipment you can inspect the soldering that way otherwise I would suggest you write a little custom code that doesn't use the SD that excised the HF and LF clocks so you can make sure they are functional.

I compared both the binaries and they are not the same. If I attach the binaries, would that help? How can I do that?

Could you read out the flash from both chips and check that they are equal?
