求助关于S3C44B0X上建立jffs2文件系统的问题
使用S3C44B0X开发板，flash为SST39VF160(norflash)，系统为uClinux。参考文章《S3C44B0X开发板上flash(SST39VF160)建立jffs2文件系统方法》
http://www.hzlitai.com.cn/article/ARM7-artilcle/cphelp/200610132.html
在启动信息中可以看到jffs2的信息，也看到了mtd的分区成功。启动uclinux ,运行earseall /dev/mtd1的时候遇到了以下问题，以下是我的出错信息：

不知道这是什么问题，还请赐教。
