lost operational code / firmware due to internal battery replacement ?


After some years of use we stop and clean C3G124-48 and also replace internal bateries after doing that never more the switch boot up to operational code.

We think the system lost the firmware due to replacement of this battery (is this possible??)

The system goes only to this line and stops.

How is possible to load again the firmware to the unit on this status.

Thanks in Advance

Try use XModem metod
Article ID: 5605 Firmware Upgrading a SecureStack via TFTP or XModem
Thanks for reply,

We know this method but on this case the procedure maybe will be "Empty Unit Firmware Loading" because is not possible to access boot menu, to use standard ID5605 method....

Cheers,
Solved !!

Symptom:

On C3 system if you replace internal battery CR2032 with the switch off you lost some boot flag or data that makes the device does not boot anymore to op code, remaining on this status.

With a cable we use oscilloscope prove make connection between ground on any point at the board and the pin 28 of U19 Intel JS28F128J3D75 flash memory this pin is A1 address bus pin, this make the Freescale processor jump to some instruction with result like this.

Hello Mike, I have same problem, I am able to access boot menu and upload new FW by Xmodem. Problem is, that it success upload, update boot code and run into operational mode, but after reset it wont boot. I have to to same thing with short 28pin of memory every time to get unit boot. Any ideas?

Solved: I had to flash few major version older fw so it flash "PROM". New PROM was also in 06.61.05.0009....Just flashing latest version is unsuficient.

Welcome to the Hub Feldsam....great to have you join us.

Better yet, great that you found a resolution to your problem. Thanks for letting the Community know.

I noticed that this thread pre-dates GTAC Knowledge, so thought I'd throw a link in an applicable article for those in the future that read this thread.

Thanks for your really quick response@feldsam
But I don´t know how to do that.
I have open a serial connection to the switch and the only message I can see is this:

did you open unit? how your problem happens? If you did not open unit and never try to replace battery them your battery is probably dead. So you need new battery, open unit, replace battery, localte that Intel chip. Conenct serial cable, connect power and short cut ground with U19 chip pin 28. Them you should see something about flash format, unit reboots and boot menu should show. you probably need to short cut circuit more times to get boot menu. them flash via xmodem firware version 06.61.05.0009, boot, save config and reboot. unit should be ok.

there is nothing to google 🙂 just open case and look for Intel chip marked U19. Dot marks pin number 1, so you have to count to 28, but you dont have, because this chip has 28pins on each side, so 28pin is on other end that pin 1. https://www.usbid.com/assets/partphotos/6B/JS28F128J3D75.jpg

Solution

With a cable we use oscilloscope prove make connection between ground on any point at the board and the pin 28 of U19 Intel JS28F128J3D75 flash memory this pin is A1 address bus pin, this make the Freescale processor jump to some instruction with result like this.

ERROR! Did not read a valid board type from PCA9555 Monitor. Read -1

so it is pretty simple, jut conenct by wire GND - some point on case with that pin 28

Symptom:

On C3 system if you replace internal battery CR2032 with the switch off you lost some boot flag or data that makes the device does not boot anymore to op code, remaining on this status.

Thank you SO MUCH for your help.
But I have a problem. My switch model is different C2G124 and I can not see that chipset.

So, you mean, connect the power and with a wire touch the box, and that spot 28 of the chip : E28F128J3A ??
It is safe for the electrical installation? I don´t care about the switch
