3620 with 32 MB internal flash

Hi,

I am trying to get 32 MB flash into a 3620. With "show flash" and "dir" I see the 32 MB but when I try to erase the flash the erasing stops after a number of eeeeeees. I guess that probably my ROM is not at a level to support the 32 MB but I could not find any information on CCO.

If somebody has a working 32 MB flash config with a 3620 I'd be happy to know the ROM version you use. Or if there are any other tricks to make it work.

Thanks,

Mat

Mat,

Here's a show version from one of our 3620 with 32 MB flash. I don't know if anything special had to be done to upgrade from 16MB to 32MB. The router is working fine. Hope this helps

Re: 3620 with 32 MB internal flash

Thanks Sean,

my ROM version is the same as yours. So I have to figure out some hardware issues I guess.

Thanks for your response.

Re: 3620 with 32 MB internal flash

Have you tried installing each flash chip one at a time and erasing it?

Re: 3620 with 32 MB internal flash

Sean,

that's what I did and I found out that three out of four 16 MB SIMMs did not look the way they should. One sent the router in a boot loop, the other one sent the router to nirvana and the third one was only halfway eraseable. So I have to send them back and get new ones.

Thanks again,

Mat
