I have a PPC440GP evaluation board ("Ebony"). I used the buildroot tools from buildroot.uclibc.org to build a cross compiler based on gcc 3.4.4. I then built u-boot by issuing
make EBONY_config make
which built u-boot without any errors. I then wrote the resulting u-boot.bin file to flash using a JTAG programmer. I set the DIP switches and jumpers according to the README.ebony instructions. When I power the board up, the following console text is generated:
----begin console output----- U-Boot 1.1.2 (Jul 6 2005 - 15:51:04)
IBM PowerPC 440 GP Rev. C Board: IBM 440GP Evaluation Board (Ebony) VCO: 600 MHz CPU: 300 MHz PLB: 100 MHz OPB: 50 MHz EPB: 50 MHz I2C: ready DRAM: I2c read: failed 4 I2c read: failed 4 128 MB -----end console output-----
and then nothing more happens. No prompt is displayed. I tried the J41/J42 bootstrap corruption directions, but it did not seem to have any effect. Could someone suggest what to do next? I assume I am supposed to receive a prompt that enables me to enter interactive commands. Is that correct?
Thanks.
Gregg
