我是使用TI SDK6,TI-BASE FILE SYSTEM

參考網路的文章,改了UBOOT,KERNEL,使用C10的TF卡,

目前做到可以上電-> Run Application 約6.4Sec

不曉得是否有機會再精簡時間到4.x Sec??

另外從下列需要花費1.8秒,不知是否合理呢??

[4.080772] Starting udev
[4.085440] Starting Bootlog daemon: bootlogd: cannot allocate pseudo tty: No such file or directory
[5.860986] bootlogd.
[5.861966] EXT3-fs (mmcblk0p2): using internal journal

下列問題我已經解決,1.8秒與這個無關!

cannot allocate pseudo tty: No such file or directory
