Hello list,

inside the automatic U-Boot patch tracking system a new ticket [DNX#2006082142000017] was created:

<snip>

Wolfgang,

this patch implements functionaly I found useful to have and hopefuly others can benefit from it too. Please drop all my previous NAND related, not yet applied patches. Once (if) applied I will rediff the rest.

Now you can do:

# mtdparts [snip] device nand0 <omapnand.0>, # parts = 5 #: name size offset mask_flags 0: kernel0 0x00400000 0x00000000 0 1: rootfs0 0x02800000 0x00400000 0 2: kernel1 0x00400000 0x02c00000 0 3: rootfs1 0x02800000 0x03000000 0 4: data 0x02800000 0x05800000 0

# nand write 10400000 kernel1 100000 NAND write: device 0 offset 0x2c00000, size 0x100000 1048576 bytes written: OK

# nboot kernel0 Loading from NAND 128MiB 3,3V 8-bit, offset 0x0 ...

# nand era kernel1 NAND erase: device 0 offset 0x2c00000, size 0x400000 OK

or

# nand era nand0,2 NAND erase: device 0 offset 0x2c00000, size 0x400000 OK

# chpart rootfs1 partition changed to nand0,3 # fsload /boot/uImage ### JFFS2 loading '/boot/uImage' to 0x10400000 ...

etc...

Best regards, ladis

CHANGELOG

• Patch by Ladislav Michl, 18 Aug 2006: chpart, nboot and NAND subsystem related commands now accept also

partition name to specify offset.
