HX3.5 SD Card Usage

SD Card content for HX3 mk5 firmware updates

A new controller firmware and FPGA image (Sound Engine) may be installed using a standard SD or SDHC card. For this purpose, an SD card adapter is provided with every board. Attach SD card adaptor cable to PL17.

Firmware images are made available through our H3.5 Github repository. Unzip and copy all files from appropriate ZIP file "SDCARD" to empty SD or SDHC card. Any computer with SD card reader may be used (Windows, Mac OS, Linux, Android). Please make sure that all files are located in the card's root (base) directory, HX3.5 will ignore files located in folder or ZIP files! Insert SD card in HX3.5 card adaptor and power up HX3.5 (Reset/Restart).

An update will start automatically on power-up when a file called "autorun.ini" is present on SD card. Once the update is completed, this file will be renamed to "_autorun.ini" to prevent further obsolete updates.

The update may be started manually by menu as well. A list of available update options (INI scripts) is displayed on the LCD; select by MenuPanel encoder knob. A script is started by pressing the encoder knob for about 2 seconds.

Important: If updating to different firmware type (eg. from expander to drawbar organ), check System Init parameters with HX35 Editor. These values are persistent even when firmware is updated. Factory programming is ADC Configuration "Swell only" for expander use, so set according to your needs.

As of today, the effects/GM DSP (firmware, GM sound banks) may be updated through USB only. See page HX3.5 DSP Updates for details.
