omap4460 fastboot

Hi,

you have to catch the u-boot (located in your board) using a serial connection by simply press 'Return' on your development pc. After this you have to send the command 'fastboot' to the board. The USB connection to your pc will be established. Now you can send the commands mentioned above from your development pc. These commands use the USB port.

Because of the nature of standard device handling in most linux systems it can be possible to run these commands as root or using a 'sudo' before each command line. You can find more information about this topic at beginning of the file 'fastboot.sh'.

In the very most cases you have to do something like this:

sudo ./fastboot oem format

sudo ./fastboot flash ...

Best regards,

i use a port cable connect to my pc, when i input "fastboot" command, it tell me there is no "fastboot" command.i execute it in windows xp terminal.can you tell me in details. i use the pandaboard omap4460

Hi Neo,

do you see any messages on the serial terminal during powering up the board (serial settings 115200, 8, N, 1, NO protocol !)?

If so, you can stop the boot process by pressing 'enter'. Enter the command 'help' in the serial terminal to check the connection. You should get a list of possible commands including the command 'fastboot'.

Did you get the list?

Do you find the command 'fastboot'?

This is valid for the bootloader u-boot used in description on omappedia.

Using fastboot on Windows:

As far as I know you can't use USB fastboot on Windows without a device driver. Check http://wiki.cyanogenmod.org/w/Install_CM_for_galaxysmtd for this.

Thanks

Neo,

Can you check for Android u-boot release? Also make sure that FASTBOOT CONFIG is enabled in the u-boot configuration

Hai......I have designed a board for OMAP 4460 processor with VAR-SOM-OM44 system on module. Could you please provide me the supporting packages and sample programs for OMAP 4460 processor so that i can learn the features of the processor by programming.
