ubuntu 10.10 下安装 IMX28 的LTIB 版本L2.6.35_1.1.0_130130_source 后完全按默认配置编译生成 update_ivt.sb 文件后无法升级，为此尝试多种方法无果，特请社区FSL及其他DX们帮忙, 先谢过
mfgtool 版本为 Mfgtools-Rel-1.6.2.048 ， 使用该版本中自带的 updater_ivt.sb 升级则没问题
注： 测试所使用的IMX28目标板为 imx28_evk 板，非我们自己的板
1. 默认 PKG_KERNEL_UPDATER=y 配置时 升级失败的打印log 见文件 Serial-COM10-04241029.txt

mfgtool 的异常为进度图如下
2. 修改内核配置（注：默认PKG_KERNEL_UPDATER=y时，CONFIG_INITRAMFS_SOURCE 为空，即上述情况 ），
CONFIG_INITRAMFS_SOURCE="/home/shltech/Desktop/ltib/initramfs.cpio.gz"
编译生成 updater_ivt.sb后放到mfgtool 相应目录下仍失败.
升级失败时的内核打印见附件 Serial-COM10-04240945.txt
mfgtool 异常进度截图如下
3. 上述问题2中， 若配置 CONFIG_INITRAMFS_SOURCE="/home/shltech/Desktop/ltib/initramfs.cpio.gz" ，则内核会出现
Trying to unpack rootfs image as initramfs...
rootfs image is not initramfs (junk in compressed archive); looks like an initrd
但 mfgtool 自带的updater_ivt.sb 则无此行打印，请问这个如何配置？
多谢

Hello PeterChan, we followed you steps above, the result is still failed,
fhe failed log as follows, we don't know what's wrong? we need your help,
we can make sure the change is ok in dir "ltib/rpm/BUILD/imx-bootlets-src-2.6.35.3-1.1.0" and "ltib/rootfs/boot/updater_ivt.bd"
if you want some code or ltib configurations , pls tell me. thank you
