Re: FreeBSD-Stack not responding
Hello Gary,
I'm working on a PowerPC target (MPC8xx), its my own HAL, based on the
VIPER
I made some minor changes to the FEX driver (changing GPIOs), but the
Ethernet works fine. I configured with Windows Configtool 1.3.net and i
am using gcc 2.95.2 (powerpc-eabi).
I suspect the problem is target dependend.
Regards
Wolfgang
