I would like to install different distribution (Gentoo Linux) on MOI Pro. I'm quite experienced with linux (Gentoo mostly) but not that much with arm-based devices and not with the u-boot and the way MOI Pro is updated so I'm not sure how to exactly do that.
I suppose I would use the kernel (including firmware and modules) provided by TBS and use Gentoo stage-3 file for arm7a which contains precompiled base system. I looked at the update files and the structure seems clear to me. I'm just afraid that if I do the update wrong, I won't be able to fix it as I suppose I need TBS system to perform USB flash update (or is that what latest u-boot does? or does it need also the TBS system to work?), web update won't be available as I would rewrite the original system and I do not have OTG cable with mini connector at hand. I was looking at the board whether there is an SD card which would make fixing easier but found none. I also though about shrinking the original partition and create another one for my Gentoo system and just pass different root to the kernel but there is nothing like resize2fs...
So any idea how to put Gentoo on MOI Pro?
