Forum Post: RE: UART0 configuration issue - TMS320C6748 DSP

Hi Sivaraj,

Thank you for the reply.

I have coded based on "biospsp_03_00_01_00\drivers\examples\evm6748\uart\src\uartSample_main.c"

According to the example, I have mapped the ECM.eventGroupHwiNum[] to hardware interrupts 7, 8 9 10 as bellow

ECM.eventGroupHwiNum[0] = 7;
ECM.eventGroupHwiNum[1] = 8;
ECM.eventGroupHwiNum[2] = 9;
ECM.eventGroupHwiNum[3] = 10;

Now, since UART0 (event38) and UART1(event 46) both map to EVT1 (refer -Table 7-2. System Event Mapping in TMS320c674x MegaModule.pdf). I had set HWI the same for both UART0 and UART1.

btw- I also tried with setting different HWI for UART0 and 1.. same result.

regards,

Ashish
