Part Number: AM2434

Hi Experts,

I am asking for my customer here.

we are refer the example MCSPI Loopback DMA, and also create the three UART2 and UART3, UART4 by using DMA mode. As showed the below project, run the project and show the error below.

ASSERT: 0.10371s: uart/v0/dma/udma/uart_dma_udma.c:UART_udmaInitRxCh:129: UDMA_SOK == retVal failed !!!

Please help to check the .syscfg configure and the project. We do not know why the Open channel for block copy failed. Thanks.

Hi Nilabh,

Any updates here?

Hi Shaoxing,

This limitation is because the number of PKTDMA channels allocated to this core are restricted to 3 in Sciclient default RM Configuration. In the upcoming AM243x release planned for next week, we have added support for board configuration tool which would help you to make updates to the default Resource configuration and increase the number of channels allocated to this core.

Do let me know if you are okay to wait for the next release, or else I can help you edit the default configuration manually.

Regards,

Ashwin

Hi Shaoxing,

MCU+ SDK Release for AM243x is planned for today and it has the resource configuration tool update.

Apologies for the delay.
