miniDSP may occasionally provide an update to the processor's MCU firmware to enable new features.
Currently, firmware upgrade is supported from the Windows platform only.

IS IN PROGRESS. DOING SO MAY “BRICK” YOUR PROCESSOR.

miniSHARC 4x8
or
OpenDRC 2x2

. The processor will be put into boot loader mode
and the miniDSP upgrade utility will start. The status line should display “Device attached”.
6.
Click on the
Open Hex File
button and select the .hex file included in the download. It will have a name like
ENC_miniSHARC_Ver2.18_SS.hex
.
7.
Click on the

button. The status bar will indicate progress.
Do not disconnect or power off
the processor during the firmware upgrade!

button, and then quit the upgrade utility.
