Hi everybody

I just received a BUG for a project and wanted to upgrade the kernel.

I tried to follow the guide to upgrade the BUG kernel [1] but my BUG does not seem to have a kernel module called bug_kflash. That’s why I think I must have a really old kernel, right? My kernel version is 2.6.19.2.

How can I upgrade the kernel from that version, i.e. without having bug_kflash?

Thanks a lot!

[1] see wiki ‘Upgrading BUG Kernel’

Ok, I found help in the IRC channel. Thanks a lot!


For other users who may be interested, the problem was that kflash was not part of the bug kernel in the very, very early releases of the BUG. The solution was to download the bug_kflash kernel module, depmod, then modprobe it. Also needed the kflash userland app to actually execute the kernel flashing. I'm going to update the wiki for all users so it's clear (for R1.1, R1.2, R1.3) for everyone how to get up to speed to R1.4.

I’m running an old HiroP with 1.0RC2 on it, so I want to make sure I’m clear (and not about to brick the unit…)

Can I just go from 1.0 to 1.3 by grabbing bug_kflash onto the unit and doing the flash (and taking care of the rootfs)?  Do I have to stop at 1.1 and 1.2?  (If so, are there different rootfs images for 1.1 and 1.2?)

I feel like I’ve left myself too far behind… :)

Hi co149, you’re best off migrating to uboot and just flashing your SD card.  I’ll whip together some steps to get this done and repost shortly.

I’ve written up a blogpost for you loyal old BUGgers.  I hope this helps.  One thing you may want to consider first though is whether you even have bug_kflash.  Try running

which bug_kflash

first to see if that program is in your rootfs.

This helps enormously. I’ve been looking at u-boot longingly because I thought I needed a handylink cable to install it. Clearly I don’t. Thanks for the help!

Well, I’d suggest emailing support@buglabs.net and asking about the handylink cables anyway.  While they’re far from ideal, they are very useful for debugging.
