[U-Boot-Users] How to program flash of omap5912osk with usb?

[Ziqi He]

Hello all:

I have downloaded the u-boot1.1.3 to the flash of omap5912osk.I can use TFTP
to download kernel to flash, but in this project I must download kernel and
root file system with USB interface. Now I do not know how to settle this
problem. How can I deal with this problem?

You can implement support for USB-based console
(enable with "setenv stdout usbtty; setenv stdin usbtty")
like it was done for the SX1 and omap1510inn board.

Then you can use standard serial download commands (loadb).

Thanks for your help.
But what kind of terminal can we use to download linux kernal to flash?
And what is the name of this terminal?

You can use any serial port on your host computer with some  temrinal
emulation program. I usually use kermit, but you might have different
preferences.

Kermit is a terminal which download kernel through serial port, but I need a
terminal which can download kernel through USB port because I can not
download kernel through serial port in this project. what kind of terminal
shall I use?

I already told you that you can implement a usbtty device which  acts
like a serial port on the host side.

Please re-read my posting.

Remember, an int is not always 16 bits. I'm  not  sure,  but  if  the
80386  is one step closer to Intel's slugfest with the CPU curve that
is aymptotically approaching a real machine, perhaps an int has  been
implemented as 32 bits by some Unix vendors...?       - Derek Terveer

I am very sorry for not noticing your good suggestion. And I have understood
your meaning. Thank you very much.

After implementing support for USB-based console ("setenv stdout usbtty;
setenv stdin usbtty") through serial port, I want to download kernel to
flash through USB port. So I connected USB port and typed the command loadb
using the terminal named Hyperterminal in Windows. But I found that the
kernel had been downloaded to flash through serial port rather than USB
port. If I cut down the connection between host serial port and target
serial port, I can not type any command. How can I deal with this problem.

"loadb" uses Kermit binary protocol. I am not sure  if  hyperterminal
can send data using this protocol.

No. If you have usbtty working, than your USB link works exactly  like
a serial port as far as U-Boot is concerned.

U-Boot is waiting for a file download using Kermit  Binary  Protocol.
Either  you  send  a  file using this protocol (which requires a tool
that implements this protocol - as mentioned before  I  recomenmd  to
use kermit), or you can terminate the download by pressing ^C.
