Hello,
We are using the new AMCC ppc440epx 667MHz chip and I am
trying to get u-boot to recognize the clock rate of the new chip (we were using
the 533MHz). I notice in the cmd_sequoia.c module that there is an option to
setup some sort of strapping in the configuration FPGA that was present on the
evaluation card. We do not have this configuration FPGA present in our
production board. Is there some sort of build flag I can specify to “hardwire”
this bootstrap information? Or at least some I can tell u-boot to startup with
the 667MHz clock rate? I believe we are using option 7 in the configuration
array for the “bootstrap” command.
Thanks,
