Other Parts Discussed in Thread: AM1808
hi:
when i insmod the edma_test.ko(compiled form sdk_1_10_00_01/Davinci_PSP_SDK_03.20.00.12/src/examples/examples-03.20.22.12/edma/edma_test.c,it's a memory to memory copy test) on my am1808 platform,the transmission nerver complete,but always got a output like this:
<callback1>:
From Callback1:DMA_CC_ERROR occured on channnel 0
From the dma driver debug info,when edma test started,the event miss interrupt happed one after another,but I don't know why ?
Any one can help me?
