I'm trying to write the stripped down version of UART driver myself and having a few issues:
I enabled the UART, along with other registers as shown below
but when I enter a character in the terminal, I see the execution gets stuck on the following in the startup file. My initial assumption was the interrupt handler itself isn't being overridden in the application but I have it defined as shown below;
Both macros correspond to UARTE0_UART0_IRQHandler so that should be fine I guess.
The call stack is as follows and the dummy handler is caused inside TIMER2_IRQHandler. Where is
TIMER2_IRQHandler being invoked from? And why does the nrfx_uart_0_irq_handler not get invoked instead?
Alsno note I have NRFX_PRS_ENABLED set to 0. Was getting a different error with that enabled
