Need assistance with firmware update (3500)

[n3tm1n]

I was upgrading a new 3500 switch to FW K15.6.0008 that was successful. From there, I tried uploading a config file template that i have used successfully on other 3500yl POE switches, but caused and error from the web gui(just and exclamation mark and no information). After trying to figure out what the problem was, I downgraded the firmware to k14.47. I then tried uploading the config file again to which it errored (this time with a message), it didn't like the space in name of the switch in the config. Remove the spaces and was able to load the config successfully. Now I am having a problem with updating the firmware. Via GUI I was constently getting a "page cannot display" message everytime I tried uploading a new firmware. I was able to upload the new firmware via USB as the new primary firmware.

Problem is, everytime I tried updating to 15.07.0002 firmware, it acts like it's uploading and the switch actually reboots automatically but the information it the GUI still says it's K15.06.0008. I have cleared the cache, etc and no luck. I logged in the switch via ssh(putty) and this is the error I get.

"Saved Crash information"

NMI event SW: IP:0x014293c0 MSR: 0x02029200 LR: 0x001/8e510 CR: 0x28000800 sp:0x04fbefd0 xer: 0x20000000

Picture is attached.

Please advise.

Hi,

Sorry but the "press any key to continue" is hiding the most interesting information regarding which task and task id  are concerned.

This need to be reproduce.

if you send me your configuration file without any modification, i should have the time to try it on next week. Just send me a private message, with the more precise step you tried.

Bye.

Hi helper,

Just sent you a PM with the config information. Details in what I did are in the previous post in this thread.

I have also tried booting from the seconday flash location and that didn't help either..

fixed my problem.

I deleted the active/primary config on the switch. Switch rebooted and created a new config1 file. I was able to log onto the switch, uploaded firmware K14.41(was default fw). From there, I started configuring the Firmware from scratch via console. Then, HP support sent me FW K15.06.0014(soon to be released) I exported the config that I was working on and uploaded the new firmware. Worked without errors!

Thanks for your assistance helper!  It was much appreciated.
