Dear all,

 

I have an issue for UART1 on iMX6SoloLite, I can't get SDMA interrupt with a data that composing exact 16 bytes, and I know that a similar problem is posted for iMX6Q below.

I configured below following the procedures written on the thread, but I still can't get SDMA interrupt..

- RXTL set to 16 bytes

- TXTL set to 16 bytes

- DMA ageing turned on

- SDMA watermark level set to 8 bytes as well

Does this solution work on iMX6SoloLite?

 

thanks.

 

BR,

Ichimura
