Comment 7 Swati Sharma 2019-03-25 09:46:46 UTC
May be need to communicate with MCA again for this issue, however for apl need confirmation from Tomi if fw is 1.75.01 or 1.75?
There were 2 fw updates from MCA
1.75    (corrected LT failure)
1.75.01 (corrected DPCD write failure at 0x5c0)
However, for both the fw on hardware page we get fw version as 1.75 only. Can this be modified?
