LINFlexD with UART+DMA caused Reset

[Siyan]

Hi, NXP,

On EB Tresos with 'SW32G_RTD_4.4_S32CC_4.0.1\eclipse\plugins\Uart_TS_T40D11M40I1R0' module, configure the 'Uart Asynchronous Method' to 'LINFLEXD_UART_IP_USING_DMA' and assign accordance DMA channel.

When the program execute Uart_Init(); and change the LINFlexD mode from Init to Normal, the SOC will reset immediately.

Please give some advices on how to solve this issue.

Hello @Siyan,

I am sorry for this late reply. Are you still experiencing this issue?

If so, please share the DMA general configuration and the configuration of the logical channels you are using for the UART configuration?

Sorry again and thanks for the information.

Late reply: The S32G has a limitation where UART 0 does not support DMA, it is noted in one of the UART manuals.
This manifests in the S32G being nonresponsive when setting uart 0 for dma (at least from my observations).
The other UART interfaces I believe do support DMA.

I've experienced a similar problem. Curious if there was a solution.
