Hello,

did you solve this issue? I am getting the same error

The trick is to note that 0xE7FE is the assembler instruction for "B ." which is just an infinite loop. That happens to be the default interrupt handler code for many systems, here's an example for IAR:

  279                                   PUBWEAK  UARTE0_UART0_IRQHandler
  280                                   SECTION .text:CODE:REORDER:NOROOT(1)
  281                           UARTE0_UART0_IRQHandler
  282    00000000 FEE7                  B .

So the vector catch is simply showing that there was an interrupt but no actual handler supplied in the code other than the default handler. For IAR the vector default file is iar_startup_nrf52.s - an assembler file - but offhand I don't recall what SES uses.

I'm using nrf52810 hardware not emulating with nrF52832 DK . I followed the instructions in the documentation for removing and adding files, as well as using Soft FPU mentioned in the other ticket.

I don't know enough to figure what the vector catch is and how to resolve.

I don't see DEVELOP_IN_NRF52832 in your defines?

Did you remove the <compiler>_startup_nrf52.s & system_nrf52.c. and replace with <compiler>_startup_nrf52810.s and system_nrf52810.c ?

If I remove nrfx_uart.c from the project it compiles, but stopped by vector catch:
