Debugging ADRV9026 JESD Framer Link

The user can refer to the “ ADRV9026 Framer Link Set Up Procedure “ in ADI EngineerZone website to know the sequence to bring up the ADRV9026 framer link. If the user find some issues during this procedure , they can follow below instructions to identify the root cause:
1. Check the JESD setting in initialization configuration file to make sure the key parameter like K(jesd204K)/F(jesd204F)/E(jesd204E) keep same with ADI EVB GUI software generated configuration file. To JESD204C, When F != 2n, the EMB(Extended Multi Blocks) should contain an integer number of frames, One multi block contain 256 octets. Each frame contain F octets..  Hence K should be set as 256*E/F..
2. During link setup procedure . After send out the sysref to Framer1. The user can read back the register 0x703D value to check if the D1 bit set as 1 or not. If that bit is set as 1 which mean the Framer1 has received the sysref correctly.
3. In the “ADRV9026 Framer Link Set Up Procedure”. After execute the step18(Request sysref to bring up Rx links) and wait 1s. The user can read back the register Framer0 register 0x6E7C & 0x6E3D. If the link setup correctly . The correct register status should be same as below:
a) The reading back 0x6E7C[D0] should be set as 1 which mean the JESD link layer has set up the sysref phase correctly.
b) The reading back 0x6E3D[D0] should be set as 1 which mean the JESD transport layer has set up the sysref phase correctly.
c) The reading back 0x6E3D[D3] should be set as 1 which mean the Local Extended Multiblock Clock(LEMC) phase (set with SYSREF) has been successfully transferred from transport layer to link layer.
