ERS2500 Agent code verification fails!!

[agiava]

Hello community
We have a lot of 2500 stack, so we decide to proceed with upgrade to firmware image 2500_440011s.img .
all work fine except for a old stack with brand "nortel" where we have a error in reboot after the update , this compromise the entire stack and force us to recover them:

this in the error :

Test ROM Config – PASSED

Test FANs – PASSED

Test Internal Loopback – PASSED

Test ASIC1 Registers – PASSED

Test PHY Registers – PASSED

Test USB Registers – PASSED

Agent code verification fails!!

>> Break Recognized – Wait…

Press ‘a’ to run Agent code

Press ‘d’ to download Agent code

Press ‘e’ to display errors

Press ‘c ‘ to clear log message

Press ‘i’ to initialize config flash

Press ‘p’ to run POST tests…


this is the only stack with unit HW verion 04 , all other is Version 08 , Release note of firmware do not contain limitation related to this....
Did you have any idea????

Thanks , Andrea.
