I am using custom board with 855Ts version D3. The 50Mhz version runs fine but the 66 Mhz version hangs or start to hang in the delay loop after a while. This happens immediately, if the CPU is warm. Obviously the timer is not decrementing. The TBSCR[TBE] bit is being set (yes the key register is used BEFORE the value is being written.) 860TD3s do not have this problem either (66 Mhz version).
Any ideas ? Do you think it is a PLL supply voltage problem or a CPU "feature" ? Thanx in advance for any helpful remarks, Nicolas ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
