Hi all,

I have a Crown Xti2000 which powers up, starts the fans display "boot-10"on the LCD and then powers up. When looking into the service manual, which has a nice flow chart it seems it stops around the moment when it is loading the DSP firmware.

The first thing which comes into my mind is ( also related to the "boot"message ) the flags is correupt. So I want to reload new firmware, whihc is niocely explained in the service manual and on several websites. However Crown removed the link from their side and I am unable to find the firmware for the Xti and the
upload tool "CLoader Utility"

It seems the USB is also nor working (heartbeat LED on the mainboard stays on instead of blinking at 1Hz as well)

So It might be I have to update via RS232 ( still wonder how the DSP program gets into the flash, I assume this is not in the LPC hex file )

Any help, suggestions and expecially firmware/Cloader would be appreciated.

Regards,
Marcel

Hi Marcel Jansen.

I've serviced this XTi platform for years and all sort of Firmware odds and bugs during boot up process came in a vast majority from corroded cooper traces or drills around the CPU or DSP ICs. Moisture/dew coming in from front grille (condensation in some cases), can destroy drills in the circuit, disconnecting upper from bottom traces and causing the CPU to detect non existing conditions like overheating, no temperature at all, low line level condition or no sound, even when the display says the amp is ready for use.

DM me with your e-address and I will send you the file you want for flashing the CPU, but if the USB isn't working, chances are you wouldn't be able to connect with the CPU and download the corresponding Firmware file.

I suggest you to inspect throughly the circuit board using the Service Manual schematics as a guide for point to point connections test between CPU, DSP and ADC and perhaps you'll find the flaw.

Hi.
I have similar problem with Crown XTi 1000.
I have bought it on eBay as not working. Wanted repair it but ...
3.3V supply was burned, and LPC2142 was burned too.Could not find XTi firmware anywhere.
I think use Flash magic utility to load firmware through J2 connector.
I would be very grateful for any help an suggestion .

Download Harman Audio Architect. it always has the most recent versions of Firmware for all the products it supports. you just have to get the amp connected to the computer and select the Firmware updater module.

Thank you for advice, but I have doubt that Auduo Architect will communicate with empty ,not programmed microprocessor.
I think, I must load any XTi firmware first time, as it is described in XTi service manual and then update it. Problem is that link was removed from Crown site and I can't find the firmware for the Xti and the upload tool "CLoader Utility" .
It would be good if someone helped me with advice and provided with XTi firmware Hex file.
Best regards.
Temuri.
