Hi, could you check the orientation of IC6? I've attached the picture of my Cronus which had the same issue, unitl I've flipped this IC the other way around.
The IC shown in the picture is in the WRONG orientation.

Hi Miero,
but what if we'll bypass just the clock signals on the Hermes, leaving all other parts working? Namely the battery circuit, so that BBB will be turned off gracefully, and there will be no voltage on the pins by the time it is turned off.
Isolator chip bypass operates well.
Now the goal is to replace the whole Hermes with a very short direct cable if possible. I do not know what the software exactly do with the IC3/IC4, wether or not the system works flowlessy with default settings. If not, it will be bit more complicated to solve.
Cronus I2S slave vs master
Hi - is it possible to feed a device that insists on being I2S master from the Chronus without major modifiations? I have a NanoSharc and was hoping to integrate it into my system:
Current: BBB->Hermes->Chronus->BIII
Proposed: BBB->Hermes->Chronus->Nanosharc->Transporter->Transporter->2XB3 (I'm breaking up a dual mono B3 because in the end I like the sound of my single B3SE Pro better).
I'm hoping to do crossover in the digital domain like I see some others have successfully done before. Why am I using the nanosharc instead of the minisharc - it's because I have one already
I saw someone has successfully wired a nanosharc directly to a BBB however I would like to take advantage of the isolation an buffering provided by the Rhea at a minimum.

I am not certain what you mean - Cronus actually expects an I2S (if you are using I2S) master In other words - Cronus is never a master of anything other than the master clock itself.
It simply also expects a source that is driven either directly or indirectly via the Cronus master clock. There really is no way around that unless you somehow drive the Cronus from the source master clock (assuming it meets the timing/frequency requirements). This is possible via direct wiring - but there would be no isolation.
Cheers!

Hi Russ - I think I muddied the waters a bit hoping to elicit more general commentary from the community if I am taking the best approach to integrating the nanoSharc into my system. The very specific question regarding I2S is if the Cronus can act as the I2S slave on the output side - in other words receive BCK, LRCK from an I2S master (in this case the NanoSharc). The block diagram provided in the Nanosharc documentation shows MCLK (optional), BCK, an LRCK flowing from the Nanosharc to the I2S source device, and the I2S data (they call I2S_INX) flowing from the I2S source to the Nanosharc. I would still use the BBB/Hermes/Cronus in the conventional way using the Rhea clocks as master for the BBB. So in this scenario the I2S outputs from the Chronus that would typically feed a DAC will feed the Nanosharc inputs instead and the Nanosharc outputs would provide two separate I2S streams to two B3s. I hope I made my question more clear in spite of my limited understanding!
Quick update: It turns out our hosting company was blocking traffic froma few countries due to a flood of malicious traffic. They are adding a firewall exception for our site, so it should be working shortly.
Seems it requires a bit more time.
What's about the RPI version of Hermes?
Will it be compatible with Tinkerboard?
I have the latest boards, just need to build and test.
My whole house has been down with flu, so just getting back up to speed.
