the problem about multi-core CPU

hi, thank for your endurant reply.

but,i always feel the mailbox has some problem in the multi-core CPU.

let us make a expreiment about mailbox in the multi-core CPU. do you like

it. we can use the two CPU to operate the address at the same which is

the address in the flash ,not in the sdram, which can increase the delay

tiem. the first, we write the intial number in the address by 0x00000000.

the second, we use one cpu to write the address by the number 0x11111111,

and use the other cpu to read the address at the same time. of course,

all of them realize by mailbox. the last, we can make a conclusion by

having a look the value from the address. right?

my ability about writing program is not well. therefore, let us write the

program together. ok? my friend. my developing board is bad and it is

repairing. it is a pity.
