It supports basic operation such as create, remove, read, and write.

Dear Kyungmin, dear Stefan,

Could you please summarize the current state of adding UBI support?

Is it correct to assume we are targetting the 2008.12 release with this stuff?

Best regards,

Not much as before,

1. Basic UBI command support.
read/write/update volume. Of course you can create & remove the volume.
2. Send ubi device from environment variables instead of hard code value.

I saw the NOR device support patch but not yet tested.

Are there the more?

Yes, I hope to merge it ASAP.

Thank you,
Kyungmin Park

I'll post some last-minute UBI fixup patches soon (this week).

Best regards,
Stefan

Hi,

As am I going through the MPC85xx reset.s code, I find this code snippet below.
I find the Config_sys_monitor is the Text_Base Address in loaded in r3, The Start Offset is zero, I am not getting why we are subtracting the start_cont with start and that addr is loaded in the link register where we jump to.

So what does the address actually refer to? Please Explain.

/* Jump out the last 4K page and continue to 'normal' start */ #ifdef CONFIG_SYS_RAMBOOT
b _start_cont

#else
	/* Calculate absolute address in FLASH and jump there

*/

/*--------------------------------------------------------------*/

	lis	r3,CONFIG_SYS_MONITOR_BASE at h
	ori	r3,r3,CONFIG_SYS_MONITOR_BASE at l
	addi	r3,r3,_start_cont - _start + _START_OFFSET
	mtlr	r3
	blr

#endif

_Start:
..
..
..
_start_cont:
..
..
..
