How to Force Firmware on an EchoDIN Processor
Issue
The Echo Control Processor in my ERP/ERP-FT/Sensor IQ is not responding to commands. It will not boot past the "Echo" splash screen. How do I reload firmware without using the File Operations menu?
CAUTION: Following this procedure to load firmware will most likely erase the configuration. Please only follow this procedure if no other option is available.
Solution
- For E-PCP Mk1:
- Obtain a copy of the appropriate firmware for your system from your Local ETC Authorized Dealer or by contacting ETC Technical Services, referencing this support post.
- Download the provided Echo Power Control Processor firmware onto a FAT32 formatted USB stick. Do not put it into any folders on your drive.
- Insert USB stick into the Echo Power Control Processor.
- While rebooting the processor, hold the Back Arrow and the Check Mark buttons.
- Firmware will now be forced onto the Echo Power Control Processor.
- For E-PCP Mk2:
- Firmware cannot be recovered from USB on PCP-Mk2, but there are recovery options.
- While rebooting the processor, hold the Back Arrow and the Check Mark buttons.
- Select one of the following options:
- Normal Boot: Attempt to boot normally.
- Boot to Last Update: Attempt to reload a cached version of the last firmware update. If the processor has never been updated or the update was corrupt, this will fail.
- Boot to FW Backup: Attempt to reload the permanent factory firmware image. This will recover the firmware version the processor was shipped with, at which point you may update the processor to current firmware normally. If this fails, Contact ETC Technical Services.
