HEllo Team,

So , after the reset , i have my Code before Code start , when i reset and come to the start of my Code the SP Point to address :

which is actually out of stack.

stack is from 0x400 till 0x7f8.Could you please help me how to do correct this such that the SP Points to 0x400 ?

The second Problem is After the Code it went to Code start then started implementing

stack pointer init

System pre_init

after that i get this folloing error

Thanks

Hi Ushma,

Are you running some example from C2000ware ?

Typically this is passed from the linker and the drivers take care of setting the stack pointer accordingly before your main code is executed.

Hello Karthikeyan

i guess it comes from the boot.asm file

but my Code runs before this , so when RESET happens it goes to my Code before going to this Code .

Thanks

Okay, in that case you have to set the Stack pointer to where you need like how the c28boot is doing.

Hope you are doing that already ?
