U-Boot for Buffalo Linkstations (7 replies)

Hello everyone,

I am still having some older Buffalo Linkstations lying around that I like to set up similar to my other NSA325. Due to restricted hardware I only like to use those as NFS-servers for rsync on another location.

I would like to use the same debian from here:
https://forum.doozan.com/read.php?2,12096
and benefit from the up-to-date kernels as well as from the possibility to boot from USB.

So I do have some questions for the LS-XHL, LS-CHLv2:
- assuming that it would be able to compile and flash this u-boot version. Would it then be possible to boot from an USB-flash drive? - Having a simple one partition layout on the installed hard drive instead of the 4 partition layout required by the buffalo boot-loader and systems
- would it remove the limit of 2TB hard-drives? as stated on the first post or could there be some more component that limits that

To give some information of what I found using a fresh installed Debian Stretch using the Debian Installer: https://miniconf.debian.or.jp/assets/files/Debian%20Installer%20for%20Buffalo%20Linkstation%20NAS.pdf

This is the output of dmesg of the LS-CHLv2

Here is why I believe that basically it should be possible:
configs in the git repo:
https://github.com/mibodhi/u-boot-kirkwood/blob/2017.07-kirkwood-tld-1/configs/lschlv2_defconfig
https://github.com/mibodhi/u-boot-kirkwood/blob/2017.07-kirkwood-tld-1/configs/lsxhl_defconfig
and here the README:
https://github.com/mibodhi/u-boot-kirkwood/blob/697f50bf18e71406db8fa9b4bf08344ae6640146/board/buffalo/lsxl/README
though I did not compile the u-boot.kwb file yet - I still would not know if I could flash it - since
the size of the u-boot part itself seems smaller then in this thread
all mtd parts together would have sufficient size - but I do not know how to handle the 3 different parts of mtd0-mtd2

Any help is welcome. I can provide more Information when needed.
