SDI video output not working in CvP mode

Hi Chee pin and John

I followed the steps mentioned in section 7.5.2. Fractional PLL Recalibration of ug_arria10_xcvr_phy.pdf

I implemented the system console command sequence as below :

# Follow these steps to re calibrate the fPLL:

# Request user access to the internal configuration bus by writing 0x2 to offset address 0x0[7:0]
#::ist::write_tcvr_pll_reg 0x000 2

#Wait for reconfig_waitrequest to be deasserted (logic low) or wait until capability register of PreSICE Avalon memory-mapped interface control0x280[2]=0x0
#::ist::read_tcvr_pll_reg 0x280

#To calibrate the fPLL, Read-Modify-Write 0x1 to bit[1] of address 0x100 of the fPLL
#::ist::write_tcvr_pll_reg 0x100 2

#Release the internal configuration bus to PreSICE to perform recalibration by writing 0x1 to offset address 0x0[7:0]
#::ist::write_tcvr_pll_reg 0x000 1

I do get the fPLL lock and SDI output is up and running successfully.

I really appreciate your suggestions
