Hello,
I am trying to implement a UART layer on the DM648 using TI sample code founder under dvsdk_1_10_00_26_DM648. When I call GIO_create():
hUart_IN = GIO_create("/UART0",IOM_INPUT,&echoTskStatus,&chanParams,&gioAttrs);
it returns a null pointer. I stepped through the function, and the problem is at this line:
name = DEV_matchJ(name, &entry);
DEV_matchJ returns null pointer, meaning that it does not recognize "UART0".
Now I am stuck. I am not able to find the DEV_match definition, so I can debug the function.
Any help/suggestions?
Thank you.
Alin
