移植新内核到QQ2440友善之臂的开发板上，开机出现了：
Uncompressing Linux...................................................................... done, booting the kernel.
Error: unrecognized/unsupported machine ID (r1 = 0x0000030e).
Available machine support:
ID (hex) NAME
000000c1 SMDK2410
0000016a SMDK2440
Please check your kernel config and/or bootloader.
看到网上许多网友说修改内核或者vivi，我后来试了一下，可以通过修改vivi的mach_type解决，具体办法如下：
Supervivi> menu
##### FriendlyARM BIOS for 2440 #####
[v] Download vivi
[k] Download linux kernel
[y] Download root_yaffs image
[c] Download root_cramfs image
[n] Download Nboot
[e] Download Eboot
[i] Download WinCE NK.nb0
[w] Download WinCE NK.bin
[d] Download & Run
[f] Format the nand flash
[p] Partition for Linux
[b] Boot the system
[s] Set the boot parameters
[t] Print the TOC struct of wince
[q] Goto shell of vivi
Enter your selection: s
##### Parameter Menu #####
[r] Reset parameter table to default table
[s] Set parameter
[v] View the parameter table
[w] Write the parameter table to flash memeory
[q] Quit
Enter your selection: s
Enter the parameter's name(mach_type, media_type, linux_cmd_line, etc): mach_type
Enter the parameter's value(if the value contains space, enclose it with "): 362
Change 'mach_type' value. 0x0000030e(782) to 0x0000016a(362)
因为看了一下刚才启动报的：0000016a SMDK2440，0x16a=362故才设置了mach_type＝362，然后下边保存
