9. Frequently Asked Questions

Q: How do I reprogram the bootloader to the original program and fuse settings?

framework corresponding to your part. See Section 7.1 for further details.
Q: I want to program my own bootloader. How do I do that?
A: You can either replace Atmel’s bootloader with your own by changing the bootloader
sources in the
JTAGICE mkII or you can extend Atmel’s bootloader with your own by enlarging the
bootloader protected area specified by the BOOTPROT general-purpose fuse bits. See
Section 7.6.3.2 and Section 7.6.3.3 for further details.
Q: I do not want to use the bootloader and I want to use the first 8 kB of the flash
for my application. How do I do that?
A: Remove the bootloader with JTAGICE mkII by unprotecting and erasing the MCU
flash array with
your project to free the first 8 kB of the flash. See Section 7.6.3.1 for further details.
Q: I do not want any ISP I/O condition with my program. Can I still use the ISP?
A: ISP I/O conditions can be suppressed by setting the ISP_IO_COND_EN general-pur-
pose fuse bit to 0. The only way of reaching the ISP is then to set the ISP_FORCE
general-purpose fuse bit to 1 from the programmed application and to generate an MCU
hardware reset. See Section 6.2.1 and Section 7.2 for further details.
Q: I do not want to use the trampoline section from the software framework but I
still want to use the bootloader. Is it possible and where should I link my
application?
A: Remove the trampoline from your project by following the instructions in Section
7.6.3.1 and link your application as if the reset vector were at 80002000h instead of
80000000h. This can be achieved by modifying the linker script you use with GCC or
IAR. Your project will then be unusable with JTAGICE mkII.
