关于IPNC_V5.1版本的内核启动不了

所以你的uboot和kernel不是来自一个RDK版本的吗，那样是不推荐的

hi Eason:
    我的UBL,UBOOT 没有用V5.1的版本的， 我用串口烧录5.1 版本的UBL, UBOOT后， 板子直接提示nand copy 那里失败， UBOOT 起不来呢。

那返回去用旧的UBL和uboot，是否直接就好了？

估计和旧的UBL,UBOOT没关系， IPNC V5.1 的内核 2.6.37的版本， 怎么差异那么大。 搞得不适应。
1.  在dvsdk_ipnctoolsipnc_psp_03_21_00_04kernelarcharmmach-davinci 目录下的 dm365.c文件中，关于UART的配置是：
static struct plat_serial8250_port dm365_serial_platform_data[] = [
 [
  .mapbase = DAVINCI_UART0_BASE,
  .irq  = IRQ_UARTINT0,
  .flags  = UPF_BOOT_AUTOCONF | UPF_SKIP_TEST |
      UPF_IOREMAP,
  .iotype  = UPIO_MEM,
  .regshift = 2,
 ],
 [
  .mapbase = DM365_UART1_BASE,
  .irq  = IRQ_UARTINT1,
  .flags  = UPF_BOOT_AUTOCONF | UPF_SKIP_TEST |
      UPF_IOREMAP,
  .iotype  = UPIO_MEM,
  .regshift = 2,
 ],
 [
  .flags  = 0
 ],
];  
而在 V3.0 内核中是：
static struct plat_serial8250_port serial_platform_data[] = [
 [
  .membase = (char *) IO_ADDRESS(DAVINCI_UART0_BASE),
  .mapbase = (unsigned long) DAVINCI_UART0_BASE,
  .irq = IRQ_UARTINT0,
  .flags = UPF_BOOT_AUTOCONF | UPF_SKIP_TEST,
  .iotype = UPIO_MEM,
  .regshift = 2,
  .uartclk = 24000000,
 ],
 [
  .membase = (char *) IO_ADDRESS(DM365_UART1_BASE),
  .mapbase = (unsigned long) DM365_UART1_BASE,
  .irq = IRQ_UARTINT1,
  .flags = UPF_BOOT_AUTOCONF | UPF_SKIP_TEST,
  .iotype = UPIO_MEM,
  .regshift = 2,
  .uartclk = 121500000,
 ],
 [
  .flags = 0
 ],
];   很明显 V5.1的串口配置少了 uartclk 等，这个不知道是否有影响呢？
 
2. 我在IPNCV5.1 版本的make menuconfig 后，里面system type里没有看到关于DAVINCI的芯片组选项。 这个是怎么回事呢？
谢谢 

关于这个问题，之前有人提过同样的这个问题。  在本论坛的另外一个人开的帖子是“内核引导失败,死在Starting kernel ...”, 我查看了， 用没有明确的解答啊。  说什么内存分配不对， 什么uboot的console，   我在Uboot里 用来ttyS0,  ttyS1, 都不行

别估计了，试一试吧。
你原来跑的是IPNCRDK还是DVSDK啊

IPNC RDKV5.1啊，名称是"IPNC_RDK_DM36x_Release_5.1.0",   就被这问题卡死了， 没法往下进展啊

我问的是之前什么版本，后面看是是v3.0  了。
建议还是换uboot吧
你用的是自己的硬件还是appro机器？

之前的版本是IPNC RDK 3.0啊， 板子是我们自己的，DDR2是三星128M BYTE,  NAND FLASH是三星32M BYTE,  没有用大菠萝的。  
你的意思是让我用新的UBOOT,  配合IPNC5.1的 uImage 吗？UBL 用5.1的还是 老的呢？   内存的分配是在UBL里吧 ？

Hi Eason:
   我刚才用IPNC RDRV5.1 包的 u-boot-1.3.4-dm365_ipnc.bin，  下载，然后烧录了， 然后跑新的内核，还是跑不起来， 卡在 "Starting kernel ...",  是否 UBL 也用V5.1 的版本？ UBL 代码默认有调试诊断模式。 那个要去掉才行呢。还要重新编译

HI Eason:
   你不在线？

我现在UBL, UBOOT 全部用的是IPNC RDR V5.1的版本， 跑uImage ，还是卡在
Starting kernel ...
什么原因啊？
FAE 人呢？

你好，
请问你使用v5.1的ubl/uboot后，uimage是通过TFTP下载的么？如果是，请尝试烧写到Nand上，boot试试。

hi Chris:
     赞啊， 你真是高手啊，烧录进去以后，可以跑啊， 现在挂mount 的时候出问题。

你好，
1. 先确认nfs是否在Linux 电脑上可以mount上？
2. 不要使用$ ($(nfshost):$(rootpath))，直接写，然后试试?
