Awesome Acko - thanks! I'm shelved it until we get more specifics. May be just me, but I can't get slave mode flashed. Tried every combination I can think of.
I'm trying to work out some CKSEL issues with my full sync install (posted a question in the Amanero thread), but I was wondering - how can I best force X1 out and X2 in (simulate pin 11 high)? I'm thinking ground pin 2 and power pin 3 of J10? would 5V on pin 3 be too much?
Amanero CKSEL Issues
Yes, you can manually select the clocks on the AKX302 module. Obviously I was thinking this would done automatically by Amanero but from the looks of it there may be a firmware issue with the Amanero unit. Until this is sorted try manually:
1. Disconnect any J10 (CKSEL) connection of AKX302 to the reclocker boards (S01/S02).
2. Tie pin#2 and pin#3 together and use the combined lines to connect/disconnect to XO 3.3V supply to select clocks accordingly.
e.g. Pin2/3 open -> X1 selected. Pin2/3 to 3.3V ->X2 selected.
I would not advise connection of the above to 5V supply as the XOs are running on 3.3V
Let us know if this works 🙂

Recieved the last PCB today. Thanks alot acko.
Although i will not build it until later when i start my headphone amp project! 🙂

Thanks Acko; it'll be great when these 'bleeding edge' applications of the Amanero are worked out. Your instructions make sense. I had to pack up my bench (in the middle of a move), so it'll be awhile before I can test and push forward. Hopefully, we'll have another firmware drop by then. Btw, boards arrived - thanks again!
Did anyone manage to workout full sync method from the last page off Acko's appnote? Did anybody flashed 1077 or 1078 firmware from oemtool114?
I have almost all the components needed except il712.
BTW, received the board also half an hour ago. Thank you Acko.

Domenico has told me a new update tool and firm should be available soon, they'll have working XO selectors and /1, /2 and /4 dividers so up to 98.xxx should work. Also plenty new useful stuff for R2R DACs.
No, not yet. Had to shelve it for a bit. My sense is that we need the upcoming firmware with CKSEL working as it should. Using slave2224 & 1074, pin 1 & 11 are not being remapped to provide the Hi/LO necessary to select the proper clock. Short of that it's working for me.
I have received my board as well. Time now to order the components and proceed.
Many thanks Acko.
Many thanks Acko.
Excellent!
With dividers on Amanero itself we can bypass the Potsemi FF divider, so do not mount this part yet on the new S03 board.
Received the boards today. Probably several days ago, as I just arrived home from holidays. Thanks.
New tool and firm available:

Slave mode reports will be much appreciated

Regarding this useful stuff for R2R DACs: you mean they want to add a third output format useable by R2R DACs: output for Data Left, Data Right, Latch and Bit CLK ?
