Segmentations faults/Bus Errors with OpenWRT+Debian on wl500gP after 32MB trick

Reported by: Orlik - cfanygapa@… Owned by: developers
Priority: normal Milestone:
Component: kernel Version:
Keywords: wl500gp Debian segmentation fault bus error Cc:


I'm using OpenWRT custom kernel to boot Debian from USB (stick/2.5" disk) on wl500gP as described in nice project under
If I'm running Debian with default 16MB of memory (sdram_init=0x000b)
everything work perfect.
If I only switch to 32MB (sdram_init=0x0009) lots of segmentation faults
and bus errors start to occur. So I cant boot my system with 32MB
because of that.
I've tried to compile many revisions (r5375 , r6850, r9442, r10517) but
problem still persists.
The funny thing is that regular (non-Debian) boot with fully flash ROM
based Kamikaze built (r10517) runs fine with 32MB enabled(!).

So I don't understand where the problem is. Kernel, nvram settings or Debian specific?
Other people run Debian with 32MB without similar problems, but I've
found their nvram's "hardware_version" value is WL500gp-01-02-00-00.
Mine is hardware_version=WL500gH-01-00-00-00. Can this be an issue? Do
I have some old trash? Do you have any suggestions? I think my problem is not connected with #2035.

I'm attaching an example serial log of failed boot with 32MB enabled


PS: If you think it's not OpenWRT related because of Debian please close the ticket.

  • Resolution set to worksforme
  • Status changed from new to closed

probably kernel specific, the newest kernel in openwrt should work much better than whatever was packaged for debian back then.
