Hi to all, I'm not able to use the devkit for unknown reason.
I'm using both usb cables, as indicated in the guide, and i can flash the FW on to the device.
does anyone have the same problem or knows how to fix it?

Hi, Did you ever solve this? I have having issues getting mine up, same FW Open Error. Thanks
Hi. unfortunately no luck here. But after a coworker of mine contacted TDK they sent us a completely new program of the soniclink with a different application note which changed a lot of stuff.
Maybe you can try to connect all the jumpers on the J3 connector of the board and use MAXIMUM 2 sensors with a sample rate of 10Hz, because that's the maximum available in the version 2.0.0 unfortunately.
My colleague was able tu run just a single sensor (of the 4 that we bought) so your mileage may vary.
Let me know if you are able to use this devkit

I signed up hoping to find a solution as I am having the same problem... I'll try contacting TDK directly to see if the issue can be resolved.
Me and my colleagues are trying to do the same. we have a call scheduled for the 6th of august. I'll update this post in case we make this board working.
On a side note i was trying out the Hello_chirp fw and discovered that they used a baudrate of 1.000.000 (which is stupidly and unnecessarily fast). probably that was the reason that lead them belive that the processor hadn't enough bandwith to manage 4 sensors. if you tune it down to 9600 probably will work better. Still the board with the sw example does not see the sensors :/
I have the same problem and find the solution here:

1.Take elf file from sonic link installation folder.
2.Program the devkit using elf file directly in Microchip studio 7.
3.Then try again connect. Issue should disappear.
