Dear Josh,
First thank you for announcing UBI support on U-boot.
Actually the Samsung implemented the UBI support on U-boot already and has used it internally. The big difference is the code base. It's based on kernel UBI code. Yes it's not fit well to u-boot ecosystem so it created the ubi wrapper for u-boot.
I saw your source codes and ubi commands. I think it supports minimal features of UBI, no volume create, remove, read/write and so on like these.
u-boot $ help ubi ubi info [l[ayout]] - Display volume and ubi layout information ubi create[vol] volume [size] [type] - create volume name with size ubi write[vol] address volume size - Write volume from address with size ubi read[vol] address volume [size] - Read volume to address with size ubi remove[vol] volume - Remove volume [Legends] volume: character name size: KiB, MiB, GiB, and bytes type: s[tatic] or d[ynamic] (default=dynamic)
I want to know what's the better way if there are two code bases.
Please give any options and comments
Thank you, Kyungmin Park
P.S., we will post the patches ASAP
As has been stated before by various people, IBM has added some form of UBI support to an older version of U-Boot. While we would love to be able to forward port this to the latest version of U-Boot, we have simply not found the time and don't see that being the case in the near future.
So as an alternative, I have cleaned up the code slightly and pushed out a version that applies to U-Boot 1.1.6. This way there is at least some form of code release that people can use as a reference. I am not pushing this for inclusion into the current U-Boot, as we are well aware of the need for further adaptation and cleanup.
...
Thanks a lot.
I guess we will pick up this work ASAP.
If anybody else has intentions to work in this area, I'd appreciate if you contact me so we can coordinate efforts.
