Hello
Recently I send data by SCI+DMA module. And I use the SCI module, which the type of the microprocessor is TMS570LS3137PGE. But I encounter a strange problem, I define the array and the transfer and receiving of DMA which are uint32(32 bit).In this way, I can send the data successfully by SCI module. But when I change the array and the transfer and receiving of DMA into uint8(8 bit),I cannot send the data successfully. I do not know why this function cannot work.
When the array and the transfer and receiving of DMA is uint32(32bit), picture is below
And when the array and the transfer and receiving of DMA is uint32(32bit), picture is below
I’m Chinese, And I ask the FAE in china but they cannot solve, so they recommend me to ask you. I hope we can solve this problem.
look forward to your reply
