Meyer Sound LX-300 manual Upgrading a System from Eprom Mode

Firmware Update Procedures

After you click OK, a blank configuration will be sent to the hardware. This is to prevent audio processing while firmware is uploaded.

Another dialog box will appear, allowing you to locate the firmware file(s).

All modules should be using the same firmware version as CueStation. There are five firmware files in each release:

lx300_vx_x_x_xx.csf

(where "x_x_x_xx" is the version number) The lx300___.csf file has two firmware files for the LX-DSP module.

et_boot_v_x_x_x_xx.csf

The et_boot___.csf file is a very small file that is the first of 3 files needed for the LX-ELC module.

etrx1_x_x_x_xx.csf, etrx2_x_x_x_xx.csf

The etrx1___.csf and etrx2___.csf files are very large and are the rest of the files needed for the LX-ELC module. All three of these must be sent to the ELC module or it will not run correctly. If only part of them are sent, you may have to force an erase of the ELC module and upload via a serial connection to an LX-COS module in order to recover. (See LX-300 ID Codes)

lx300exp_vx_x_x_xx.csf

The lx300exp___.csf file is used to upgrade the firmware in both LX-EXP Expansion DSP modules, and for LX- VRA VRAS modules.

Make sure to select all five files when uploading firmware, or one .zip file that contains all files. Hold down the Shift key to select multiple files at once.

Tip

When uploading firmware, you can select a .zip file, or multiple .zip files, and the .csf firmware files will be extracted automatically.

5. Upload Firmware Files

When you have selected the files you wish to upload, click Open to upload them.

You can watch the progress on the front of the LX-300 as the files are transferred. You must wait for all files to complete the transfer and be written into flash memory. If you shut off the power before the process has completed, the LX-300 will not operate correctly. If this happens you may have to use the special DSP module ID codes to erase flash memory and then connect using a serial cable to an LX-COS module in order to recover. See the following part B.

6. Confirm Upload Success

Once the firmware upload is complete, there will be File Complete... messages in the log. If you uploaded all five firmware files, you should see six File Complete messages: one for each DSP in your system, plus an additional one from the main DSP. All DSPs should now be online.

7. Power Cycle LX-300s

Power cycle all LX-300s in the system. When they finish powering up, there should be messages in the log reporting the firmware version, so you can double-check that the firmware upload succeeded.

Unsuccessful Uploads

If the firmware upload was unsuccessful, you may have to erase the flash memory and upload the firmware over a serial connection. See the following section for details.
