After configuring the test pattern (either custom pattern or toggle pattern), the most significant pair of both channels (DA10P & DA10M and DB10P & DB10M) doesn’t behave like the rest of the pairs, which prevents us from synchronizing.
The configuration registers were written as follows:
Addr Data
REG0 8'h0
REG25 8'h05
REG29 8'h18
REG2B 8'h05
REG3D 8'h0
REG3F 8'h2a
REG40 8'ha8
REG42 8'h08
REG4A 8'h00
REG58 8'h00
REG2 8'h00
REGD5 8'h00
REGD7 8'h00
REGD8 8'h00
I'd be happy to provide more information as requested.
