eDMA EDMA_TRANSFER_SIZE_16B error

[hicensezhang]

when I create a new project from example edma_transfer_s32k144, I wang to transfer 16B , so I  change

transferConfig.srcTransferSize = EDMA_TRANSFER_SIZE_4B;

transferConfig.destTransferSize = EDMA_TRANSFER_SIZE_4B;

to

transferConfig.srcTransferSize = EDMA_TRANSFER_SIZE_16B;

transferConfig.destTransferSize = EDMA_TRANSFER_SIZE_16B;

But the dstData displays all zero not the srcData content

could you help it? thank you

Hi, have you changed MINOR_LOOP_BYTE_COUNT as well?

[hicensezhang]

I only change the

transferConfig.srcTransferSize = EDMA_TRANSFER_SIZE_4B;
transferConfig.destTransferSize = EDMA_TRANSFER_SIZE_4B;

to

transferConfig.srcTransferSize = EDMA_TRANSFER_SIZE_16B;
transferConfig.destTransferSize = EDMA_TRANSFER_SIZE_16B;

, others has no change.

And that's exactly the mistake if I understand what you want to do.
