Using CRC + DMA Controllers



Hi, everybody.

In my continuous adventure with TMS570 I have already achieved good results with programming FLASH with API functions and now trying to reveal all other Cortex-R4 safety-critical functionality. It is essential for my project to make periodical CRC check of FLASH contents with minimal CPU intervention in the process. Exploring the CRC section in the TRM (spnu489a), I have read that MCRC controller can work in conjunction with DMA controller. So that's just what I want. Is it possible to post some code examples to start working with CRC + DMA, or may be there is such an application note to be written in the near future?

In advance thanks, Evgenyy.
