I am working whit m52235evb, whit internitche OS.
I am trying to extend 2 uarts to support 3rd uart (uart2).
I allredy:
1. extended uart_desc uarts[]
2. uart_init
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?
Did you place the jumpers correctly ? (UART2_EN and COM_SEL)
Do your init routines take in account that PUCPAR is a DUAL function register on a 52235 ? (in contrast to PUAPAR and PUBPAR, those are QUAD function)
Hello, I have noted with MCF52235EVB and FNET 0.8.1 and setting:
FNET_CFG_MCF_SERIAL_PORT_DEFAULT (2)
a problem related to PUCPAR that is DUAL and not QUAD.
In particular using boot demo examples.
Thanks to highlight the difference.
Best regards
Gianluca
