请教关于VXI—MIO—64XE-10在的dma channel错误。

[情义天天]

安装NIVXI331（完整安装）后PCI-MXI卡被系统认出并自动安装完成驱动程序；安装

NIDAQ693后运行MEASUREMENT&AUTOMATION后执行VXI RESOURCE MANAGER

系统认出 VXI—MIO—64XE-10但是其NI—DAQCONFIGURATION 在执行TEST RESOURSE 时提示 THE  DEVICE  IS  NOT  RESPONDING  TO  THE  FIRST  DMA  CHANNEL；TEST  PANEL运行SHRIP  CHART 模式可正常运行，但是ONE SHOT和CONTINUOUS模式无法正常运行，提示-10845错误。

-10845   overFlowError   Because of system and/or bus-bandwidth limitations, the driver could not read data from the device fast enough to keep up with the device throughput; the onboard device memory reported an overflow error.

Using a VXIpc-8xx and a VXI-MIO-64E-1 to acquire data will return an error code of -10845 when you add more system RAM. This is because the NI-DAQ driver software is attempting to transfer data to the new RAM, but the VXIpc-8xx will not allow it.

To correct this problem, you need to share all of the new RAM.

1. Launch VXIEdit.
2. Go into the VXIpc-8xx Configuration Editor.
3. Select Logical Address Configuration Editor
4. Change the VXI Shared RAM Size to something other than 'Share All Memory' and then back again.
5. Close this window and select Update Current Configuration.

This will allow NI-DAQ to use the new RAM.
Have a try with the steps above.

Good luck!
