KV5 DMA and UART

pietrodicastri — Mon, 12 Jan 2026 16:53:22 GMT

Good morning

I imported the example for using the UART and DMA. The original example has the UART0. It works. I changed for using other ports, now I try with UART4 and it does not. I can see the callback called for the and of TX but never for the end of RX. I don t get the point. I am sure the pins and the connections are ok. I am using the tower system for the KV5.
I drop here the example with minor modifications for changing the UART.

Every help is welcome..

Thank You

Pietro

Hello Pietro

Could you help us confirm which UART-DMA example are you using and which SDK version is it from?

Could you help us share your connections?

Best Regards, Luis
