Hi Georgy,

Unfortunately, we don't have any TI-RTOS SPI example with uDMA. TI-RTOS does not have drivers for uDMA for TM4C129 device. However, after some forum searches, I found this post with the similar question. The poster posted his code. I hope it is something you can compare with your own project and see for similarity and differences.
