currently I play with the I2C facility of PPCBoot 2.0.0 (I know, it's 
deprecated). At my TQ850L I'm using the I2C hardware machine 
(CONFIG_HARD_I2C) with needed configuration:

   * CFG_I2C_SPEED=400000
   * CFG_I2C_SLAVE=0x7f

Why don't you use the default of 0xFE?

Hm, what's the meaning of CFG_I2C_SLAVE ? I've expected it's the highes valid 
slave address, isn't it ?

No, what makes you think so? It's the value that gets programmed into
the MPC8xx I2C controller's I2ADD register. See the Users Manual  for
details.


The subject suggests you ntended to ask something different?
