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...

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?

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?
You can use tftp to reflash the bootloader onto the ppc board.
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.
