Hi Jon,
The email address you used for Jon is invalid (we need to update the maintainers file - Jon should weigh in here).
I am using 2009-06 u-boot for MPC8640D based custom board. i justwant to know whether the second core of MPC8640D is kicked off automatically or will it required by the user to kick using cpu command
If you have U-boot configured as you say below, and an SMP linux, then the second CPU will automatically come up. You don't need to do anything special.
like mpc85xx/mp.c. Also if am enabling the CONFIG_MP macro and CONFIG_NUM_CPUS as 2, then the reset command of the target is not working(means board is getting hanged). I have mentioned the value of CONFIG_SYS_SCRATCH_VA as 0xf5000000.
As far as your reset problem, I'm running a MPC8641D board using the latest u-boot, and I am able to reset it just fine when booted SMP. You're going to have to provide more information or look into this yourself.
I can't tell you if your SCRATCH_VA is valid without knowing the entire memory map of your system.......
Cheers, Becky
