Hello,

I'm trying to send some data with DMA and SCI on Hercules,TMS570LC43X launchapd ,but have a problem.

I used the attached example from HALcogen,and tried to send some data with DMA and SCI,but couldn't send data with DMA.

The sci3 module works normally (if without DMA).

I build project exactly as the HALcogen LC43 help procedure.

7823.Project5.zip

please check my code！

I would appreiate if someone could reply to my question.

Hello,

Can you check in the HalCoGen the MPU setting for the RAM starting at 0x08000000 and see if it is configured for write-through cache or write-back cache? If it is write-back cache then change to write-through cache and let me know if it makes a difference.
