5 Firmware update
5.1 Introduction
The C1 D/A Controller is built around multiple programmable circuits. This approach allow the unit to be updated to support new
features. It includes a host micro-controller, a display controller, several FPGAs (Field Programmable Gate Arrays) and DSPs (Digital
Signal Processors). When optional boards are added, even more programmable circuits are in use inside your C1. All of these
components run firmwares which can be updated when needed, for instance to support additional features or to correct a bug. The
following sections describe how to update the complete firmware of your C1 unit.
5.2 Firmware Update procedure
5.2.1 Preparing the firmware image
Before doing the actual firmware update, it is necessary to prepare the firmware update image. Firmware update images are
available in the form of compressed .zip files from our website at www.ch-precision.com.
The following procedure shows how to prepare the firmware image:
1. Start by downloading the latest C1 firmware image from www.ch-precision.com
2. Prepare a blank, FAT32 formatted USB stick. Please note that some USB sticks are not properly detected by the USB
interface of the C1. CH Precision have tested successfully and therefore recommends Sandisk USB flash drives.
3. Decompress the firmware image .zip file to the root of your USB stick
After doing so, your USB stick should contain the following files:
• C1_xxx.ds1 & C1_xxx.ds2: Firmware update file for main C1 DSPs and audio streaming DSP
• C1_xxx.fp1 & C1_xxx.fp2: Firmware update file for C1 FPGAs
• C1_xxx.mc1: Firmware update file for C1 Micro-controller
• C1_xxx.ol1: Firmware update file for C1 Display controller
where 'xxx' indicate the software version number.
Make sure all six files are present at the root of your USB stick. Any missing file will prevent correct operation of the firmware
update procedure.
