I am working whit m52235evb, whit internitche OS.
I am trying to extend 2 uarts to support 3rd uart (uart2).
1. extended uart_desc uarts
3. extended processor_UART_ICR_init
4. added vectors and defines in vectors.s
5. added __interrupt__ uart2_isr
Interrupts on sending are working, but i dont get anything back, when making hardware loopback.
Does anybody have at least a stupid idea what am i missing?
