Questions about SDMA in SPT in MPC5775K

Hello

 

I want to see the sampled data from SDADC which used SDMA to be transfered to SRAM. However I found no changes in SRAM that the address I set in SDMA and there were all zeros. Then I found the flag FRM_ACQ_DONE and CHRP_ACQ_DONE was set which shows the acquisition was done. As a summary, the acquisition of sdadc was done but the data seemed not to be transfered to SRAM by SDMA.

I will attach my code.

 

Regards

Hai
