In the process of building JESD204B, the SYNC signal has been unable to pull up. Keeping track of the states of deframer and framer gives the following:
Deframer status = 0x12; Framer status = 0x02;
We use JESD API (JesdBringup) as is with slight changes (excluded from code):
1. We mask the parts of "FPGA framer & deframers"
2. We use a scrambler - both Rx & Tx path.
According to this information, what can cause this behavior? What we are missing?
