My cpu is MPC5748G with Z4_0.According to the datasheet,the Cpu core clock can up to 160M(HZ).
my circuit is that:
When I use lwip_5748G demo project running in the core,the fasted bandwidth perform differently with diffrent CPU core clock setting.
the fault setting is like this:
On this case, the bandwidth can up to 3.9M.And the cpu timer is not accurate.
when I change the setting like this:
the bandwidth can only up to 1.2M.And the cpu timer is much more inaccurate compared with the default setting.
Can someone explain that condition for me ? And how could I set the CPU core clock and CPU bus clock correctly?
Thanks very much!
