LP-AM243: Ethernet/IP and UART with UDMA can not run normally at the same time？

Shaoxing Ke

Part Number: LP-AM243

Hi Experts,

I am asking for EIP customer here.

Customer add two UART w/UDMA on the EIP Demo. EIP Demo: C:\ti\mcu_plus_sdk_am243x_08_06_00_43\examples\industrial_comms\ethernetip_adapter_demo.

And the project build shows no error, when load to LP-AM243, click Run button, the console do not see any output here. When we stop, finds the code stuck at HwiP_undefined_handler.

Could you help on this case? Thanks a lot.

Hi Shaoxing,

Could you please try below fix:

In syscfg open the UART module that you added then click the UDMA configuration

Change the instance : BCDMA -> PKTDMA

We have tried the example from SDK no changes in ethernet ip_mii example, just add UART and change it to pktdma and build and run the example
