MADI Sync Symbols Problems

[Twister10000]

Hello together

I am new to this forum.
I am currently working on an FPGA MADI transmitter.
Unfortunately, I cannot read from the specifications exactly how many and when sync symbols have to be embedded.
The transmitter currently sends the symbols so far that the receiver recognizes that it is a 64CH/48kHz frame. However, the receiver reports that there are sync symbols in the audio:/

If someone could help me I would be very grateful.

Kind regards

Darn, that's a great undertaking. Sorry can't help (but will ask around)

Can't really help specifically here sorry. But got me wondering:
is MADI still a "Thing" ?
For context I was working professionally with Digital Audio protocols and interfacing back in the 90s when it was the "multichannel king/queen "
But MADI was peripheral as I was dealing with AES-3 etc; IEC950/SPDIF; ADAT; TDIF (an excellent though now abandoned format imnsho).
wrt MADI - IIRC it was originally based around Mitsubishi chips - maybe some help around that ?
