Title: uboot as bootloader?
Post by: DiTBho on January 08, 2021, 01:16:50 pm
hi
is there any attempt to use uboot as bootloader?
I'd like to use the serial console.

Let me know.
Thanks!

There are older versions of u-boot available for the SL-C models which were shipped together with pdaXrom:

http://distro.ibiblio.org/pdaxrom/download/

r197/r198 are the latest versions, depending on the Zaurus model you own. The archives containing "u-boot" in their name are the u-boot binaries.

Here you'll find the instructions on how to flash it (unfortunately from archive.org, since the pdaxrom site is offline):

Note that the installation is not for the faint hearted, you need to follow the instructions carefully in order to not brick your device. You can find some on-topic posts in the pdaxrom board: https://www.oesf.org/forum/index.php?board=73.0

BTW what's your Zaurus model?

isn't there any source repo about uboot/zaurus?

That's cool! If possible, could you please share a tarball of it? I'd like to give it a try, and I believe others might be interested too. We can host the archive here on OESF.

AFAIK only the diff of the changes have been shared: http://distro.ibiblio.org/pdaxrom/download/u-boot/

May be in the future. There is a lot of broken stuff at the moment.

My current stage4 is based on an old kernel 2.6.23 and a 2007-8 stage4 with some modern updates/patches/workarounds that I have made year after years, plus some personal applications written by me. For me it's "ok" as I have been using daily it since 2007 and I can coexist with all the problems it has, but with my recent needs I myself have reached the point where there are so many broken unstable things that the new plan for the 2021 is to prepare a full set of recipes for Catalyst and launch it to build a completely new stage4. But first I have to find a valid candidate for the kernel of which I I have to have to the full trust about mobility because I seriously need to use my PDA on traveling.
