ANDROID PORTING到S3C2443的板子上 KERNEL發生錯誤，請問要如何解決？

 版上各位前輩你(妳)們好：

小弟要移植到SAMSUNG的S3C2443板子64MB SRAM，128MB NAND FLASH，KERNEL做出來後用KERMIT燒進去NAND，板子開機，結果停在KERNEL解壓縮的時候，是有錯誤訊訊息，錯誤訊息如下：

想請問要如何解決阿@@？

還有有人有做過可以在s3c2443跑的KERNEL  ，可否給我KERNEL IMAGE，我想知道是UBOOT錯誤還是KERNEL錯誤

另外ANDROID SYSTEM 我已經把他編譯出來了，而且是ARMV4指令集的，想請問那個是ROOTFS？還有這板子跑的動ANDROID嘛？
