例えば、デバイスドライバが現在の転送操作に対して InterruptExpected Boolean を保持している場合、 StartIo ルーチンはこの変数を TRUEに設定する場合があります。 ドライバが現在の操作に対してタイムアウトカウンタを保持している場合、その StartIo ルーチンはこの値を設定するかも...
如果非虚拟微型端口支持StorPortInitializePerfOpts) 设置的并发通道优化 (STOR_PERF_CONCURRENT_CHANNELS,则可能会同时多次调用HwStorStartIo。 在这种情况下,微型端口需要确保任何共享资源都受锁的保护。 通过此性能优化,Storport 在调用HwStorStartIo之前不会获取 StartIo 锁,并且微型端口必须根据需要提供自己的锁。

HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, data, 1); it returns HAL_ERROR and well, the CCR1 value doesn't get updated. I tried to troubleshoot it but kind of reached an impass. I traced the origin of the return value HAL_ERROR: ...
I noticed when I asking for example a Block Transfer Size equal to 10, I think I should to see 5 Chip Selects to low with 16 clocks. But always, the first time than I start DMA it always show to me 6 Chip Selects to low with 16 clocks and yes the next ones ar...

I was running Lion up to the point till this happened and now today I installed Mountain Lion and I am running OS X 10.8.4 to see if it would fix it and it has not. I tried restarting the PRAM and that also did not work, any advice would be very helpful. Thank you. Jonathan ...
The test cmd is './dma_from_device -d /dev/xdma0_c2h_0 -f data/output_file.bin -s transfersize -c 1' If I transfer 4KB(transfersize ) one time, the driver work correctly. When I transfer 1MB(transfersize ) one time, the driver return error. ...
