stm32 cube dma memory increment dont work

[Arman Ilmak]

Hey guys.

I generated a cube uart transmit receive dma but in case of receive only the first byte of my buffer is overwritten and memory wont increment.

Whats the problem?

Have you set the bit?

[Arman Ilmak]

hdma_usart2_rx.Init.MemInc = DMA_MINC_ENABLE;

yes.and is uart-msp init dma memory increment is enabled.

You have the right transfer count set? Circular or non-circular?

Does the UART keep DMA-requests coming? How is UART idle interrupt handled, and does it exist in your chip?

Are there situations where the UART and/or DMA is reconfigured?

Have you checked for possible errors in DMA and UART status registers?
