DIY SA9227 USB to I2S Bridge

I recently made this module for testing the SA9227 chip functions.This chip supports up to 384K/32Bit PCM and DSD256 outputs according to it's datasheet.
I tested the 384K/32Bit output using it's official ASIO driver with a PCM5102A module without any problem.
The size of this module is about 35x25mm,which makes it can be easily apply on a portable DAC design.

No need for development of software.Just flash the firmware
provided by the seller into the EEPROM and it works properly.
That's much easier for DIYers.
If you just want to choose a USB-I2S/DSD module, just go for
the XMOS one.
 
Hmm.I just can't find any design files and firmware for XMOS.
The ASIO driver I use for SA9227 was found on Google.But you can also use the default USB audio driver on Windows 10.It also works well.I can't hear any difference between the ASIO driver and the default one.

where can I find the firmware? I have a device on this chip, but the firmware does not work there. could you send your firmware? maybe my problem will be solved.
