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.
