TMS320F28P650DK: CPU falls in ITRAP in dual cores

Part Number: TMS320F28P650DK

Tool/software:

Hi Champ,

I am asking for my customer.

CPU1 has encountered some problems with functions and variables.

We tried to define function in different ways. One as an object, the other directly call function. The former way (#1) could cause CPU trap.

#1 functionA. func. update (& variable)

#2 functionA_update (& variable)

The variable currently resides in Ramsg0, which is not assigned to CPU2.

Part of the function is stored in Flash Bank 0, which is also not assigned to CPU2.

Both CPUs should be able to call the function and reach the variable, right ? 

Regards,

Johnny
