I try to burn the file system and kernel to nand or nor flash through mfgtool, it is feasible? cause I have succesed to burn them to SD card, but when I try the flash, the push command failed. my ucl.xml is as follow:

<CMD type="push" body="send" file="files/u-boot.bin">Sending U-Boot</CMD>

<CMD type="push" body="$ kobs-ng init --chip_0_device_path=/dev/mtd2 $FILE">Flashing Bootloader</CMD>

<CMD type="push" body="$ flash_eraseall /dev/mtd0">Erasing Kernel partition</CMD>

<CMD type="push" body="send" file="files/uImage">Sending Kernel Image</CMD>

<CMD type="push" body="$ nandwrite /dev/mtd0 -p $FILE">Flashing Kernel</CMD>

<CMD type="push" body="$ flash_eraseall /dev/mtd4">Erasing rootfs partition</CMD>

<CMD type="push" body="pipe tar -jxv -C /mnt/mtdblock4" file="files/rootfs.tar.bz2">Sending and writting rootfs</CMD>

<CMD type="push" body="frf">Finishing rootfs write</CMD>

<CMD type="push" body="$ umount /mnt/mtdblock4">Unmounting rootfs partition</CMD>

and i always stop at mknod command,forgive my poor English

Hi Jacky

Probably you used wrong image, recommended to use MX53 SMD Linux.

Please use "cat /proc/mtd" to check the right partitions for NAND

In MX53 SMD, mtd0 and mtd1 are for SPI-NOR; mtd2 - mtd6 are for NAND

L2.6.35_11.05_ER_SOURCE : Linux 2.6.35 Source Code Files and documentation 11.05 for i.MX53 SABRE Tablet.

thanks for your replay! i was using MX53 LOCO，the partition for NAND is accroding to the normal kernel，i was wonder why it is failed at mknod class/mtd,mtd0,/dev/mtd0 but pass at mknod block,mmcblk0,/dev/mmcblk0,block， is it means my mtd is not working？otherwise,my purpose is it feasible,can i burn them to the nand flash through mfgtool directly?

Hi Jacky

MX53 LOCO has not NAND so you see these errors,

please use BSP for MX53 SMD - it has NAND on board and its

BSP supports NAND.

hi igorpadykov ：i got another question。my mtd partition of the normal kernel is

	dev: size erasesize name
	mtd0: 00400000 00040000 "kernel"
	mtd1: 03c00000 00040000 "usr-romfs"
	mtd2: 00200000 00010000 "spi1.2"
	mtd3: 04000000 00020000 "home-romfs"
	mtd4: 1c000000 00020000 "user-nand-jffs2"

	1f00 4096 mtdblock0
	1f01 61440 mtdblock1
	1f02 2048 mtdblock2
	1f03 65536 mtdblock3
	1f04 458752 mtdblock4

mtd0 and mtd1 are for NOR; mtd2 if for SPI flash, mtd3 and mtd4 are for NAND

but in the mx53_smd mtd0 and mtd1 are for SPI_NOR from what you said. is that means i must modify the partition as same as the normal partition for the mfg image?

Looking forward to your reply.

Hello guys,

Have you ever encountered this problem while trying to boot board with eMMC booting configuration but nothing in eMMC card?

As you know that will lead to USB serial downloader mode, and booting with uboot and kernel provided by mfgtool.

But here comes the problem with default initramsf file
