[U-Boot] about flashing the u-boot

[Érico Porto]

Hello!

Is it possible to flash a ppc board, that already has an older u-boot
version, without using a jtag interface? I mean, I know I can write the
filesystem using tftpboot, is it possible to also use it to write over
u-boot? If no, is there any alternative to use jtag?

Got a USB TAP, but unfortunately it is supposed to be used with Code
Warrior. Any software that allows me to use it to flash a ppc?

You can use tftp to reflash the bootloader onto the ppc board.
Which board are you using?
I can give you the instructions for it.

Just be aware that if the new image doesn't work, you'll need jtag (or
an alternative boot source such as NAND) to recover.

I use a board created by some guys in the company where I`m a
internet. It uses the u-boot-1.1.6-mpc832x_rdb.spec file on ltib to
build it. And I do have the memory map for it - where in flash goes
what..

I thought some memory manipulation commands on boot could help me to
do a write over, but wasn`t able to find out how.

Meanwhile, I got usb tap and code warrior borrowed from one guy there
just to do this, but I really wish to not need to use this...

I recommend just using the current mainline U-Boot from denx.de.

The benefit to using the usb tap the first time is that if you get it to
work once, know you can get it to work again if you need to recover.

Got usb-tap to work, but ONLY with code warrior - and for some reason can
run it on ubuntu+unity but not on ubuntu+xfce, which loads everything
except the action button in the flash programmer where you select what you
will do: flash dump, erase, write...

Any open alternative to use usb tap or someone know where is the command
line tool that is used by the CW IDE?

If I find it out, I post it here...

Abatron BDI3000 is a popular choice.

The command line backend is called CCS (not sure where in a typical
installation you'd find it) -- but the flash programming logic is in CW
itself, so if you want to do flash programming with CCS directly you'll
need to script it yourself.

thank you, found the ccs interactive shell, it is located in

/usr/local/Freescale/CodeWarrior_PA_10.1.1/PA/ccs/bin/ccs

I has many commands, has help commands in it, and also have
autocomplete feature with tab.

Just trying to find a command that let me connect to my usb tap.

Thank you!

(bin) 1 % config cc usb
(bin) 2 % ::jtag::get_pin 4
USB open failure

ok, give up.
