Hi,
I'm trying to write a Linux Device Driver for the PXI-6533, which transfers data from the PC to the board using DMA. When I first load the driver after a reboot, everything works fine. However, if I unload and then reload the driver, DMA transfers are terminated immediately after the DMA is armed. The channel status register of the PCI-MITE contains the following value: 0x82808284 (which appears to be reporting the following error: Transfer Error => Memory Error => Bus Error). The only thing that seems to fix this problem is a system reboot.
How do I fix this Bus Transfer Error? Any help offered would be greatly appreciated.
Regards,
Ninh Duong
