Other Parts Discussed in Thread: TMS320F28035

Hello  Community, 

i'm working with tms320f28035. At the moment i have a several problem with the stack size. One idea to enlarge the stack  is to store  constant data, wich i receive over i2c, in the on chip flash. Is this possible without using the flash api?

Best regards Lukas

    Lukas,

    To program the flash in an application, the flash API must be used.  There is no way to do what you've suggested without it. 

    Perhaps you could allocate a buffer in RAM to store this constant data instead of using variables that will be placed on the stack?

    Regards,

    Trey

    Hello Trey,

    i suspected this. I don't think that this will solve the problem because the stack overflow take place without accessing these data.The workaround is as follows, i have about 0x300h ram left in L0+L1 and a 0x320h stack in M0. The only way  I see to maximize the stack is to minimize the data section instead. 

    Regards Lukas
