fully functional vga terminal

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

baudrate=115200river module lo

loadaddr=0x70800000oot:  3 i.MXC CPU

bootcmd=run bootcmd_mmc

stdin=serial

stdout=serial

stderr=serial

Environment size: 1086/8188 bytes

 

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.

 

thanks,

snir.

i understand that but my question is why?

why the original uSD freescale provided came with a fully functional terminal that i can install gcc and download and instakk packages from the internet and i can't create OS that do the same for just compiling "all available packages" and setenv for networking?

how else can i install pkgs like samba4 and winexe for example? i need to  download them to the host install them and then check them when the "configure kernel" menu is up during LTIB build?

another question about using LTIB.

what i need to check in the ./ltib -c menu in order to build just the kernel again with just a few more pkgs, i mean that when i choos "don't build the bootloader" and then "configure the kernel" and "always rebuild the kernel" i'm getting the menuconfig and then i need to choose by my self all the pkgs that allows boot? what the "install all available pkgs" in the second config menu after installing ltib ( how to i bring it back with reinstalling?) change about the pkgs i need to choose my self in the menuconfig?

 

thanks,

snir

Hi,

What all the softwares that are available on normal linux are available in the pkgs folder on your host.

So you just need to check them in the menu config when ./ltib is done and cross-compile and do the rest.

Your ported OS will not have a gcc / arm-none-linux-YYY to compile the source code!

thank you,

isn't it possible to install packages the same way it's can be done when using the gnome terminal with commands like wget,git,apt-get install etc.?

Hi,

If you have to install a package, then you have to do that when configuring the ltib itself.

There, you cross-compile it and use it in your port to i.MX.

o.k s oi really don't have a luck today... the vga coneector is broken from the board...

i can still use the debug uart but i dont think it's possible to develope and use the OS throught hyperteminal (correct me if i'm wrong please...)

is there a way to get the terminal (root@freescale ~$) to be a fully functional terminal like lucid@lucid$ terminal in the original uSD through hyperterminal?

anyone have a another possible solution? the deadline of the project is coming in giant steps and i'm totally frustrated.

well i think that some how there is a problem with the vga connector...

i tried inserting the original microSD and i'm not getting vga too.

i know that usually there is a current leakage from the vga that lights the FLT and 5v leds but now it's not happen.

how is it possible?!?!?

is there a clever solution to that kind of situation?

well i PING sucessfully.

 i also tried: setenv bootargs 'setenv bootargs console=ttymxc0,115200 console=tty0 video=mxcdi1fb:RGB565,VGA-XGA di1_primary vga'" but no change i still get only the root@freescale ~$ in hyperterminal and nothing on the screen.

this terminal in hyperterminal can be used to install packages such as git wget or samba?

how can i get it to the vga screen?

here is my enviroment:

 sata access: SATA will be detected as /dev/sda. If there is file system it will be detected as /dev/sda1 .... You need to mount this access.

ethernet :The bootargs already already has ip=dhcp. so already network should have configured. Try to ping to the computers on the same network

fully functional terminal in the vga : Make sure boot args has console=tty0, for example as below

setenv bootargs 'setenv bootargs console=ttymxc0,115200 console=tty0 video=mxcdi1fb:RGB565,VGA-XGA di1_primary vga'

 

 

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

Edit /etc/rc.local file to start the program automatically after boot.

Hi. I maybe can help with a couple of questions.

Attached find a file that talks about configuring these parameters. It says in its title EVK but talks about other boards (such as START board) as well. Here it states the configuration for booting from SATA and VGA for START Board (page 14).

There you can also find how to update just the Kernel (uImage) - page 12, basically it is:

sudo dd if=uImage of=/dev/sdb bs=512 seek=2048 && sync && sync

of -> shall be the SD card you want to update.

Hope this helps.
