Re: [U-Boot] Enabling nand createbbt command
Thank you Scott and Fabio,
You help is much appreciated.
I will try to add the nand support for mx53 mainline.
However, what I am trying to do is to build a u-boot that supports NAND and have YAFFS2 as well and at moment I use the mx53_ard board since this is very close to what my custom board will be. I was able to build such a version, using Freescale u-boot sources, which included nand subsystem, and yaffs commands. Then I needed to create partitions in the nand and this is where i "discovered" I needed the support of mtdparts command.
So I, guess, I need to configure the u-boot for mtdparts support. This is where I am at.

I do expect mainline is better maintained and supported, except for missing particular features/hardware support that nobody ever bothered
to submit to mainline -- which in this case appears to be hardware that you care about, so unless you're prepared to do a fair bit of work to add support to mainline, I'd try again to find a support channel for your Freescale-provided U-Boot. Or maybe we could help you figure out what it is you want to do, instead of scrubbing, if the
answer doesn't depend on details of a non-standard U-Boot.
Oh, and if you're curious about my freescale.com e-mail address, I work in a different part of the company and don't have i.MX knowledge or contacts.

Yaffs can work without mtdpart. To do that you just need to configure the start and end blocks manually instead of using the partition info to do this.

That is interesting. Any clue how to configure the start and end blocks manually?

Yes I do since I wrote yaffs :-).
Set the statrt_block and end_block (might be startBlock and endBlock) values as needed BEFORE the mount/init happens.
In a "normal" situation with mtd partitioning these are set to 0 and n-blocks-in-partition -1, but they can be set manually too.

I looked at where I could set the startBlock and endBlock (btw - start_block and end_block are used in cmd_onenand.c) and I saw that in yaffscfg.c (flashDev->startBlock = 0; for yaffsVersion == 2).
Is this the place do change flashDev->endBlock = nBlocks - 1; to flashDev->endBlock = N - 1, where N desired number of blocks?
Also, do you have or can point me to a comprehensive YAFFS2 commands document?

Yes, that's the stuff to modify. It might even make sense to add u-boot commands to set these.
Also, do you have or can point me to a comprehensive YAFFS2 commands document?
I have never used yaffs in u-boot myself. have a look at the commands for the yaffs code.
