Hi Andreas, I also read that it's typically around 100 MHz, but as you said its implementation defined and since it's implemented in Gem5 I thought it would be best to ask here. However I just saw this in Realview.py
timer0 = Sp804(int_num0=34, int_num1=34, pio_addr=0x1C110000, clock0='50MHz', clock1='50MHz') so I guess it's more like 50 MHz for this board. Could someone confirm this?
