最近搞了一下eeliod的linux2.6.38移植，把XSBASE270_EDR平臺加了進去，其中MACHINE_START模塊在下面
#if defined(CONFIG_ARCH_XSBASE270_EDR)
MACHINE_START(XSBASE270, "51Board XSBase270-EDR Development Platform "
#elif defined(CONFIG_ARCH_XSBASE270_DVK)
MACHINE_START(XSBASE270, "51Board XSBAse270-DVK Development Platform "
#endif
.phys_io = 0x40000000,
.boot_params = 0xA0000100, /* BLOB boot parameter setting */
.io_pg_offst = (io_p2v(0x40000000) >> 1 & 0xfffc, // BOOT_MEM(0xA0000000, 0x40000000, io_p2v(0x40000000))
.map_io = xsbase27x_map_io,
.init_irq = xsbase27x_init_irq,
//.fixup = fixup_xsbase27x,
.timer = &pxa_timer,
.init_machine = xsbase27x_init, //FIXUP(fixup_xsbase27x) MAINTAINER("51Board Inc."
MACHINE_END
booting the kernel之后沒有反映了，終于查到了一個辦法去除printk緩沖區(qū)，是這樣的：

說明start_kernel已經(jīng)調(diào)用，MMU也已經(jīng)開啟，這里在初始化頁表之后進行首次malloc，但是就出錯了這是怎么回事？我在啟動參數(shù)那里添加了MEM=64M。
萬望幫幫忙，謝謝！ |
