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 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- , 使用该版本中自带的 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




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 则无此行打印,请问这个如何配置?
