10.3.2 macOS / OS X
To load firmware using macOS / OS X requires that you use the Terminal program (located in the
Applications/Utilities folder). In the examples that follow, black text is the “prompt” printed by Terminal, blue
text is text typed in by you, and red text is the program output.
It is important that you type exactly as shown including characters like “.” and “/” where noted. Press
the Tab key after typing the first two characters of any filename, to activate auto-completion.
Download the latest software for the SHD Series processors from the User Downloads area of the minidsp.com
website. Double-click on it to unzip it. Assuming that you have placed it into the Downloads folder on your Mac,
you will then type:
mac:~ me$ cd Downloads/SHD_v1_0/XMOS_Firmware/
mac:XMOS_Firmware me $ ls
SHD_XMOS_v1.5.bin miniDSP_UAC2_DFU_OSX readme.txt
mac: XMOS_Firmware me $
You see in the above list the name of the firmware file, SHD_XMOS_v1.5.bin (the version number “v1.5” may
change). Now change to the folder holding the actual firmware upgrade tool, and then run it:
mac:XMOS_Firmware me$ cd miniDSP_UAC2_DFU_OSX/
mac:miniDSP_UAC2_DFU_OSX me $ source setup.sh
mac:miniDSP_UAC2_DFU_OSX me $ ./xmosdfu --download ../SHD_XMOS_v1.5.bin
