S32K344 Boot jump to App, then Used Uart Async Send ,DMA interrupts are always called

[sun15021414801]

1.I use the s32k344 can from the unified_bootloader_demo_V2.1 project to implement the bootloader

2.app uses the ETAS integration package and the compiler is ghs

3.boot jumps to the app, RTA-os is already running

4.when I called Uart_AsyncSend, dma interrupts are always called, jump to the dma interrupt handling function, Can't jump out

Please Help, thank you

1.I used Uart Interrupt mode, dma has never been used

2.boot's code is essentially unchanged, as shown in the figure

3. jump start address is 0x440200 , After entering the app the interrupt vector table was also re-registered
