How to format UBIFS with Linux-3.9.y

Hi, All

My system is imx28 with nand booting. With porting Linux-2.6.35, an update_ivt.sb can be made and download by mfgtool to format the nand chip for UBIFS including make ubi volume etc. When moving to Linux-3.9.7, for fast map of UBI, the previous tool doesn't work anymore because lack of dtb file. Please let me know if there is a way to make a new update_ivt.sb supporting dtb config, so that we can still use MfgTool in volume production. Thanks!

Are there any hits for booting mainline Linux-3.9.y without dtb? Thanks

Hi Cheng, by choosing the " Support for the traditional ATAGS boot data passing" option in the menuconfig you might be able to use traditional ATAGS to pass data to kernel. Your boot loader needs to support this as well.

Hope this helps

Thanks for quick reply. Actually, I do need a way to boot the 3.9.7 kernel without u-boot just like updater_ivt.sb in case of 2.6.35.

Hi Chen, sorry I am not familiar with updater_ivt.sb . But if you build the kernel with the option I mentioned, it will look for the board information in that ATAGS structure. Anything that boots the kernel would then need to pass this structure in the corresponding register. Perhaps that updater does something similar.

Hope this helps
