RTOS/PROCESSOR-SDK-OMAPL138: Upp driver Issue in SYS/BIOS

Bhargavi Ale

Tool/software: TI-RTOS

Hi All,

I am working on uPP driver on LCDK-omapl138 platform. I have successfully migrated DSP/BIOS uPP Driver to SYS/BIOS and it is working properly with Digital loop back in both scenarios (i.e., LOCAL_mode_BA_dlb & LOCAL_mode_AB_dlb), but whenever I configure upp_mode as either of LOCAL_mode_A_transmit mode or LOCAL_mode_B_transmit , I am not receiving any interrupt for transmission.

After debugging I come to know that uPP Driver is generating interrupt in Digital loop back only.

Can anyone help me where I am going wrong?

Thanks in Advance...

Hi,

Did you set up the irq enable register correctly? See Section 2.8 Interrupt Support from the uPP User Guide:
www.ti.com/.../sprugj5b.pdf
to see what are the requirements to the ISR. Also check the sample available in Section 2.6 Initialization and Operation to see if you initialize the uPP transactions correctly.

Best Regards,
Yordan
