mx28,is there a example which use the uboot to burn ubifs rootfs to nandflash by tftp or mmc??thanks!!

[HaohuaQIN]

Before,when debugging embeded linux system(like as TI's am335x),i usually  receive ubi.img through TFTP in uboot,and then burn to nand rootfs mtdpart.like is:

tftp 0x82000000 ubi.img; nand erase 0x780000 0xF880000; nandecc hw 2; nand write 0x82000000 0x780000 ${filesize}

And,when small production, i usually read ubi.img from mmc in uboot,and then burn to nand rootfs mtdpart.like is:

mmc rescan; fatload mmc 0 0x82000000 ubi.img; nand erase 0x780000 0xF880000; nandecc hw 2; nand write 0x82000000 0x780000 ${filesize}

It's so fast and convenient.

i want to know that wheather in the mx28 uboot,can do it at the same as above??

thanks!!

ubinize.cfg:

[rootfs]

   mode=ubi

   image=ubifs.img

   vol_id=1

   vol_size=80MiB

   vol_type=dynamic

   vol_name=rootfs

   vol_flags=autoresize

mkfs.ubifs -r rootfs   -m 2048 -e 126976 -c 1900 -o ubifs.img

ubinize -o ubi.img -m 2048 -p 128KiB -s 2048 ubinize.cfg

I test that tftp update rootfs to nandflash is ok!!

I haven't test mmc update rootfs.

Hi Haohua

please look at link below it explains methods of

in mx28_evk.h i add define parameters

#define MTDIDS_DEFAULT "nand0=nandflash0"

#define MTDPARTS_DEFAULT "mtdparts=nandflash0:1536k(bootloder),"\

                                                "512k(params),"\

                                                "18m(kernel),"\

                                                "-(rootfs)"

I use 128MB nandflash,20MB (0x1400000)for boot and kernel,the rest(0x6c00000) for rootfs.

in uboot,i use this cmd:

tftp 0x42000000 ubi.img

nand erase 0x1400000 0x6c00000

nand write 0x42000000 0x1400000 ${filesize}

uboot print:

MX28-QHH U-Boot > tftp 0x42000000 ubi.img
