Hi, it indeed has nothing to do with the toolchain. And I have found the problem is the stack overflow of my task in freertos. Thanks a lot again and have a nice day !

In fact, they recommend Segger Embedded Studio - which comes with GCC as its toolchain.

They provide SES projects for the examples.

So start a separate thread on that.

but the 52832 only has one hardware UART peripheral?

Maybe.

It's possible that you may have something incorrectly configured, which causes a problem which does not manifest during the initial connection ...

You need to use the debugger to find where & why it's failing ...

Thanks for reply. The gcc toolchain is recommanded by nordic, C:\Program Files (x86)\GNU Tools Arm Embedded\7 2018-q2-update\arm-none-eabi. My main job is debug the two uart peripherals. When add the peripherals, 52832 ble is not working. Remove them, ble is ok. So I don't think it is the problem of toochain. If it is, ble won't work from beginning.

Yes, of course Keil and GCC are entirely different products!

This really has nothing specifically to do with nRF - the same applies to porting any system from one toolchain to another:

Although the 'C' language is standardised, the standards make many things implementation-defined - and a few which are undefined.
I don't think I've ever come across a compiler which doesn't add some proprietary extensions.
As well as the compiler, you need to consider the other parts of the toolchain, which are beyond the scope of the 'C' language definition - in particular, the Linker.

So what debugging have you done to find where the problem(s) is/are ?

Rather than try to port the Keil project, I would suggest that you start afresh with one of Nordic's specific GCC projects - to give you a known-good starting point.

Once you have that working, you can start to merge in your functionality ...
