[U-Boot-Users] HARD_I2C support problems

[Tales Toledo]

Hi,

i am trying to communicate with lm75 dtt but i2c seems not work
properly in hard mode.
The u-boot serial prompt get stucked in transmission state.
I am using MPC885 and u-boot 1.3.0. Ucode patch is disable.
Did anybody have a similar problem?

Thx,
TT
