[eDMA for eQADC in MPC5554]

[HungNguyen]

Hello,

I'm using eDMA to tranfer conversion command to CFIFO of eQADC and get conversion results from  rFIFO to RAM by eDMA.
When i compiled  my project by  CodeWarrior, the program runs well. But when using GreenHill, the eDMA channel 1(for example)  transfers result from rFIFO to RAM only one result and then stop.

Can you help me!

Thanhs a lot,
Hung

Did you managed to solve the problem?

If not, you could post the transfer descriptors and command queues.

my guess:

- check that the qadc is sending the result to the same rfifo where your edma is picking it up

- check that you have actually set the CFFEn and CFFSn to generate edma request

- check that  the edma is correctly pointing to the pop register
