Uncompressing Linux... done, booting the kernel.
衬托完了，我要说我的问题了，我在kernel.org下载的Linux-2.6.35.7用s5pv210_defconfig来配置，它的机器码也是 0x998，修改debug串口为0。可是我编译过后，用提供的u-boot来进行引导时打印信息为： U-Boot 1.3.4 (Oct 8 2012 - 23:15:30) for SMDKV210 CPU: S5PV210@1000MHz(OK) APLL = 1000MHz, HclkMsys = 200MHz, PclkMsys = 100MHz MPLL = 667MHz, EPLL = 96MHz HclkDsys = 166MHz, PclkDsys = 83MHz HclkPsys = 133MHz, PclkPsys = 66MHz SCLKA2M = 200MHz Serial = CLKUART Board: X210 DRAM: 512 MB after init sequence,gd->bd->bi_boot_params:30000100 Flash: 8 MB SD/MMC: Card init fail! 0 MB NAND: 512 MB In: serial Out: serial Err: serial checking mode for fastboot ...
