| |
Hello,
We have Synopsys Designware DMAC Controller on ST SPEAr13xx platform. When i run dmatest for all 8 channels then i see following error some times.
"dma dma0chan7: BUG: All descriptors done, but channel not idle!"
I saw the code in driver, and i think it looks to be a known issue for this peripheral, that's why special handling is done in driver.
Can somebody please confirm, if it a known issue or not? Or if there are some solutions for this problem.
viresh.
