Hello experts,
I have implemented the HDMI display control design in Vivado 16.2. The design works fine, but there is a small abnormal situation that every time I get DMA error: Start read transfer failed 9, when re-launching the application without newly programing the FPGA. I debug the VDMA register and get following printout:
AXI_VDMA - Partial Register Dump (uBaseAddr = 0x43000000):

AXI_VDMA - Checking Error Flags
Is it correct? In the xstatus.h file, it says that the device need to be reset, but I thought that by vfb_common_init and vfb_tx_init the device has already been reset.
Do you have any idea about it, how I could solve the error?
Best regards, YM
