The choice of firmware affects the operation of the USBStreamer, as follows. In each case, there are two different
files, identical except for ID number, so that two USBStreamers can be connected to the one computer.
ADAT_I2S
These files will receive and transmit eight channels of audio in ADAT format via the input and output
optical connectors. The sample rate can be 44.1 or 48 kHz.
I2S_TOSLINK
These files will receive and transmit eight channels of audio over the I2S headers, and two channels
over the optical connectors. The sample rate can be 44.1, 48, 88.2, 96, 176.4, or 192 kHz. (All
channels must run at the same sample rate.)
LowSampleRate
These files will receive and transmit eight channels of audio over the I2S headers. (The optical
connectors are not active.) They will support low sample rates, down to 8 kHz.
TDM
These files are will receive and transmit eight channels of audio over the TDM headers. (The optical
connectors are not active.) They will support of 48/44.1kHz
Now you will need to copy your chosen firmware file into the miniDSP_UAC2_DFU_OSX folder, and then change to
that folder, like this:
mymac:Firmware myname$
cp I2S_TOSLINK/USBStreamer_Up_TOSLINK_v5_ID1.bin miniDSP_UAC2_DFU_OSX/
mymac:Firmware myname$
cd miniDSP_UAC2_DFU_OSX/
mymac:miniDSP_UAC2_DFU_OSX myname $
Then run the firmware updater, like this:
mymac:miniDSP_UAC2_DFU_OSX myname $
source setup.sh
mymac:miniDSP_UAC2_DFU_OSX myname $
./xmosdfu --download USBStreamer_Up_TOSLINK_v5_ID1.bin
