Dear Sirs:

A simple question: How do I set the stack pointer in ccs using c?

Thanks,

Hi John,

Please use intrinsic function "__set_SP_register()" to set the stack pointer. Some other useful intrinsic functions for your reference.

Thanks, Winter Yu, you're a lifesaver:

I'm writing a bootloader for the project. Have the .hex file downloading but it isn't quite right. Does strange things which may be due to improper stack initialization. I'll try setting the stack pointer with your information.

Could you please also tell me where to find the startup code as I probably need to include this in the bootloader?

Thanks,

John

Hi John,

In debug mode, you can click hardware reset and you can see the startup code in boot.c.
