general question

As I understand you want to put the kernel console output to the USB-to-Serial device. If so then pls follow steps below,

1) Open “filesystem/etc/init.d/rcS” and add “mknod /dev/ttyUSB0 c 188 0” just below line “mknod /dev/ttyS1 c 4 64”

2) Open “filesystem/etc/inittab” and replace the line

" ::respawn:/sbin/getty -L ttyS1 $(fw_printenv baudrate | cut -d "=" -f 2) vt100" with

" ::respawn:/sbin/getty -L ttyUSB0 $(fw_printenv baudrate | cut -d "=" -f 2) vt100".

3) Rebuild the file system.

4) Use the Linux kernel with built-in USB host driver and USB serial class driver.

5) Connect the USB serial cable to Host machine.

6) Boot the Linux kernel, you should get the console.

Note: Please note that serial baud-rate value will be taken from u-boot environment variable

Kailash,

Please contact your local TI engineer on this setup. I think there is setup issue with bootargs and filesystem as indiacted in my earlier mail.
