Hi,
My hardware environment: MPC7447A + MV64460, and I ported u-boot from board Db64460, now everything seems OK but the timer can't work as expected.
Exception hanlder was installed in start.S:
STD_EXCEPTION(0x900, Decrementer, timer_interrupt)
I do not modify this code. But get_timer always return 0. I check the global parameter: timestamp. It always been 0 after set_timer(0);
It seems that the timer_interrupt handler does not been called. But if I added a print in this hanlder, system will crash after interrupt_init.
What's the possible problem?
Thanks.
