ADC-DMA Test can't work on STM32H757 i-EVAL Board

[HYeh.2233]

I want to test ADC-DMA function on STM32H757 i-EVAL Board. But the result is DMA transfer error. I just copy the example code of STM32Cube --- STM32H743I-EVAL\Examples\ADC\ADC_DMA_Transfer to my STM32H757 project.

When execute the code, it occurs only once DMA1_Stream1_IRQHandler.

And the result is DMA transfer error, TEIF1 in DMA_LISR is "1".

My IDE is "System Workbench for STM32"

Can any one help me to solve this problem?

Thanks for your help.
