Also (no offence meant) but did you remember to switch the DAC SPDIF selector off?

Hi Russ:

Yes, I did switch the SPDIF switch to "OFF" (it's marked on my Buffalo as "1" - I had it at "ON" before).

I did not connect the ground wire as I use the same Placid HD that powers the Buffalo to power the Cronus - I read in this case the ground need not be connected between the Cronus and Buffalo.

I tried just using the Amanero alone as you suggested but it would not lock either. This is how I connect the two:

Amanero BCLK - B II DCK
Amanero FSCLK - B II D1
Amanero Data - B II D2
Amanero GND - B II GND

I am using a Mac BookPro with OS X 10.7.5. Is there anything I need to configure on my Mac?

Thanks!

I did just try connect the ground wire, together with DCK, D1 and D2, between the Cronus and the Buffalo. It still won't lock.

I also installed the Mute and Lock LED's.

My goal, of course, is to get the Cronus to work with the Buffalo II. What do you suggest I try next? Also, how do I change the Amanero firmware back to master and how do I change it back to slave later? I read that Brian primed the firmware before he shipped the boards out.

Sorry for these ignorant questions, I am a DIY hobbyist and lack engineering knowledge especially with the digital.

Are there some test points on the Amanero I can measure with my DMM and report back?

Also, I read on the forums that there are different ways of connecting the Amanero to BII. For I2S output, is the following correct?

Thanks!

Amanero BCLK - B II DCK
Amanero FSCLK - B II D1
Amanero Data - B II D2
Amanero GND - B II GND

When I play music through the Cronus/Amanero combo it does show progress through the music. But the B II stays at Mute state. Here are two screen shots I took. Do you see anything out of order?

I am trying to figure out how to check the Amanero firmware versions with my Mac.

Hi Russ:

I was able to install the correct Amanero Config Tool on my Windows laptop and, following the steps in the readme file erase and flashed the firmware and re-installed the CPLD firmware (Salve_for_1080) and CPU firmware (firmware_1096c3w2) successfully. I then went into the Configuration bits and configured the Amanero based on what you posted at the DIYAUDIO thread. However, the Amanero/Hermes/Cronus still would not lock. I tried both the PC I used for the firmware refresh and the MacBook Pro. Both stayed in the Mute state and won't lock.

There are a couple of things that are out of ordinary (at least not what I expected). When I connect the Amanero back to the laptop and launch the Config Tool, the Firmware Programming tab always shows CPLD_for_1080 for the CPLD firmware and the Configuration bits tab always revert back to the setting where the Salve Mode is unchecked and Pin 11 clock selector Map has "Mute" checked. More than once I update them and click on "Write Flash" and I would see the message "Flash Updated!" but if I close the Config Tool and reopen it again it would go back to its old state with Slave Mode unchecked and Pin 11 at Mute. Did I do something wrong or out of order?

Thanks!

If I was not clear in my last post - I only got the Amanero alone in master mode to work with the B II. I am still not able to get the complete Amanero/Hermes/Cronus/Rhea package to work with the B II.

Also, am I correct that the Config Tool I downloaded in Amanero's oem_tool_117 zip file only allows one to install/update CPLD and CPU firmware and set the configuration bit. It does not show the existing firmware version and configuration of the connected device?

Any help or information is much appreciated.

Thanks Russ.



To make sure I understand what you are saying above; I can always see the progress of the music playing in iTune when I connected the Amanero/Hermes/Cronus to by B II even though the B II would not lock to the incoming signal. If I unplug the USB cord from my Mac, the music would continue to play but through the built-in speakers on the Mac. I assume you meant this indicates the Amanero is getting a master clock in slave mode?

I will do a close inspection of the boards including my own solder joints tonight and report back my finding.

Hi Russ:

I checked both the Cronus and Hermes boards for possible cold solder joints on the Potato chip and other components but did not see anything obvious. I reflowed a few of my own solder joints just to be sure. I then re-flashed the Amanero with correct CPLD and CPU firmware and set the configuration bit to slave mode and all.

I hooked it up to the B II and there is no lock - the Mute LED on the B II stayed on the whole time. I made sure the output is directed to the USB and I could see the music playing in progress.

Sorry I don't have good news to report. What should be the next step?

Thanks!
