hello everyone,

well finally i got a new uSD card with u-boot kernel and fs.

the only thing now is that i'm not having a fully functional terminal in vga... actually i'm not having nothing in vga( no penguin or anything...) , just in hyperterminal (with usb to serial).

my enviromnet looks like that:


MX53-LOCO U-Boot > printenv primaryrt clock    : mxc_

bootdelay=3beo stop au

bootcmd=run bootcmd_mmc

and if i'm not stopping autoboot i'm login with "root" and getting root@freescale ~$ prompt.

1) how can i modified it to have: sata access, ethernet and a fully functional terminal in the vga that i can use with a usb keyboard?


2) is there any document that describes all the enviroment variables possebilties and syntax? where can i find it?


3) how can i update only the kernel in the uSD?


4) how can i make the board compile and run the project code automaticly after startup?


i know i've asked a lot of questions but i think it's better then open a new thread for each one of them.

please replay even if you have answer to just one of the quiestion.
