Now,I want to write uboot_ivt.sb into spi flash, write the kernel and rootfs into NANDFLASH. But I just saw a tool "Mfgtools" to write imx28_ivt_linux.sb and rootfs.tar.bz2 into SD and NANDFLASH. Who can help me how to write uboot_ivt.sb into the spi flash?
Thanks!According to your tips,imx28_ivt_linux.sb had been writen into the SPI norflash.Then I jumper to SPI2 start, but no information.In my opinion, the imx28_ivt_linux.sb can start from NANDFLASH, should be able to start from the SPI NOR.
IMX28 can not use the uboot and directly support imx28_ivt_linux.sb.

Hi,
Please try below command and it could be found in rootfs once the i.MX28EVK has been boot. However, it has to build the "Test and Develop profile" in Ltib, then you could type the mtdxxx and see it.
burn SPI NOR-Flash memory
mtd_debug erase /dev/mtd0 0x0 0x400000
mtd_debug write /dev/mtd0 0x0 <data length> <full_path>imx28_ivt_linux.sb
Hi
Did you try this http://imxcommunity.org/group/spansion steps on your code?
