U250: DMA test failed

[KhoiNghiem]

Hi, I have just installed a new U250 on my server, using Centos 7. I have followed the UG1301 to perform installation. But when performing xbmgmt validation, DMA test failed at Test 5:

Test 5 [0000:21:00.1] : dma
Description : Run dma test
Details : Platform path not available. Skipping validation
bandwidth.xclbin not available. Skipping validation.
Error(s) : Failed to find xclbin 'bandwidth.xclbin
Test Status : [FAILED]
I don't know where this error comes from, please help me fix it. Thank you !!
