CVAVR bootloader doesn't start

Question

Codevision avr v2.60 evaluation

• Trying to make new project with wizard.
• Set all the init values to 0 (not used).
• BOOTRST bit is set to 0 (reset from 0x7000 byte address).
• Project option is set to "bootloader 2048w" (mega32).
• Programming with avrisp mk2
• If I compile this project as a bootloader it doesn't work but when as an application it works fine
• Fuses and init stay the same or get changed, not important as such.

I've got this problem trying to make bootloader for some of my well-working projects.

What am I doing wrong?

Answer 1

In addition to resetting BOOTRST you must also change BOOTSZx bits accordance to your boot size.
