Hello
I try to run u-boot-2009.11 on the chip P2020 from SDcard.
When i run u-boot i see in the terminal:

CPU0:  P2020E, Version: 2.1, (0x80ea0021)
Core:  E500, Version: 5.1, (0x80211051)
Clock Configuration:
       CPU0:1200 MHz, CPU1:1200 MHz,
       CCB:600  MHz,
       DDR:300  MHz (600 MT/s data rate) (Asynchronous), LBC:37.500 MHz
L1:    D-cache 32 kB enabled
       I-cache 32 kB enabled
I2C:   ready
SPI:   ready
DRAM:   1 GB

Failed reading I2C Chip 0x18 on bus 1

And u-boot get stuck.
I would like to enable the output to the console debug message.
But i can't find how to enable that function.
How can i enable the debug output ?


Thanks
