I work with a specific board at the following frequencies:
MPC8260 Clock Configuration
- Bus-to-Core Mult 3x, VCO Div 2, 60x Bus Freq 33-100, Core Freq 100-300
- dfbrg 0, corecnf 0x08, busdf 3, cpmdf 1, plldf 0, pllmf 1, pcidf 3
- vco_out 133332000, scc_clk 33333000, brg_clk 33333000
- cpu_clk 99999000, cpm_clk 66666000, bus_clk 33333000
CPU: MPC8260 (HiP4 Rev 14, Mask B.1 4K25A) at 99.999 MHz
Quote from the MPC8260AEC:
"The user should choose the input clock frequency and the multiplication factors such that the frequency of the CPU is equal to or greater than 150 MHz and the CPM ranges between 66–233 MHz."
Is it possible that my CPU's low frequency has somehow caused problems with caches?
