xdma driver install failed about aws-fpga HOT 4 CLOSED

Hi,

Please check if you have xocl or edma driver installed already. If yes, then remove these before inserting xdma module.

lsmod | grep edma
lsmod | grep xocl

Let us know if you still continue to see issues.

Thanks for replying so fast
I've removed xocl driver, and install the xdma driver again, but one of the error still exists

Can't read private key

I use

lsmod | grep xdma

and I can see xdma modules
But when I checked the /dev/ directory, I still cannot find device like "xdmaX_h2c_Y"
It seems xdma driver is not successfully installed.
Could you help me to check out ?
Thank you!

Hi forcici,

This is not really an error that should stop the installation.

Can't read private key

Can you try clearing the fpga slot first by calling:

sudo fpga-clear-local-image -S0
AFI          0       none                    cleared           1        ok               0       0x071417d3
AFIDEVICE    0       0x1d0f      0x1042      0000:00:1d.0

After that if you run sudo make install, it should bind the driver to the cleared AFI.

Make sure that you run the following in case you've installed any of these drivers before:

sudo rmmod edma_drv
sudo rmmod xocl

Let us know here if this doesn't help!

Thanks for you response.
I tried what you told me to do, and then I reboot AWS cloud service. Now I am able to find xdma device in directory /dev/*
Thank you !
