我买的是TQ2440开发板,查看贵公司的“TQ2440开发板使用手册V2.0_20091105”linux实验部分是在超级终端上进行开发板的。可是我设置好超级终端和开发板连接好后,开发板上电从NOR FLASH启动只能进入以下界面:
##### Boot for Nor Flash Main Menu #####
[1] Download u-boot or STEPLDR.nb1 or other bootloader to Nand Flash
[2] Download Eboot to Nand Flash
[3] Download Linux Kernel to Nand Flash
[5] Download CRAMFS image to Nand Flash
[6] Download YAFFS image to Nand Flash
[7] Download Program (uCOS-II or TQ2440_Test) to SDRAM and Run it
[8] Boot the system
[9] Format the Nand Flash
[0] Set the boot parameters
[a] Download User Program (eg: uCOS-II or TQ2440_Test)
[b] Download LOGO Picture (.bin) to Nand Flash
[l] Set LCD Parameters
[o] Download u-boot to Nor Flash
[r] Reboot u-boot
[t] Test Linux Image (zImage)
[q] quit from menu
怎样才能进入对开发板的调试模式了?谢谢!
