Re: XS1-L1-USB-AUDIO-2.0 48pin board identification problem
So... There was a fatal mistake of switching between usb_dm and usb_dp :0 After fixing this: We managed to get USB communication and to identify the board as Thesycon XMOS-L1 audio 2 device! In addition, we were able to get a very similar to RD signal on the SPDIF_TX. For this purpose, We have used ...

Re: XS1-L1-USB-AUDIO-2.0 48pin board identification problem
Hi Bianco! :) Actually we have not verified the USB - we were able to determine that the XMOS is "alive", meaning, we could burn the flash and program the XMOS to toggle a port. I have found that we've stupidly switched the USBdata+ and USBdata- Problem is that before this diagnosis, somet...

Re: XS1-L1-USB-AUDIO-2.0 48pin board identification problem
Another question Bianco: Let's assume I have implemented the Reference Design with the exact same pin assignment; with only two changes to the system: 1) using the XS1-L1-TQ48-C5 instead of the 128-pin 2) using the AT25DF021 instead of the AT45FS010 SPI Flash I made the following changes to RD code:...

What do you mean by "HID example" exactly?

Re: XS1-L1-USB-AUDIO-2.0 48pin board identification problem
SHORTER VERSION: Development stage: The HW is 48-pin embedded USB to SPDIF board based on the single channel reference design(RD). I've Successfully connected the board to XTAG and managed to burn the SPI flash. Problem: I can't get the board to be recognized by the OS. I already have the Thesycon ...

XS1-L1-USB-AUDIO-2.0 48pin board identification problem
hey All! I have built an USB to SPDIF board based on the single channel reference design(RD). The board is very similar to the RD (uses the 48-pin XS1-L1 instead of the 128-pin, different SPI flash- AT25DF021 and IC oscillators instead of the crystals in RD). The board uses no DAC, and exports the e...

Re: XS1-L1-USB-AUDIO-2.0 48pin board debug problems!!
Good news guys!!
I've managed to access the chip from the XDE!
The problem was improper physical connection between the pad and chip leg of "TCK".
Thanks for the help.
Regards,
Elad

Re: XS1-L1-USB-AUDIO-2.0 48pin board debug problems!!
First of all hi and thanks for your helpful comments. Bianco: JTAG must be connected correctly because it identifies the Reference design board which I also have. The board connectivity layout should be correct but I will look into it again. By the exposed pad you mean pin 49 (the big square in the ...
