Debugging
Debugging with AVR JTAG ICE mkII
Figure 2-10 . Connecting AVR JTAG ICE to AVRUSBKey
The Flash, EEPROM and all Fuse and Lock Bit options ISP-programmable can be
programmed individually or with the sequential automatic programming option.
Note:
The AT90USBKey can be used for debugging with JTAG ICE MK II.
Connect the JTAG ICE mkII as shown in Figure 2-10, for debugging, please refer to
AVR Studio® Help information.
When using JTAG ICE MK II for debugging, and as AT90USB parts are factory
configured with the higher security level set, a chip erase operation will be performed on
the part before debugging. Thus the on-chip flash bootloader will be erased. It can be
restored after the debug session using the bootloader hex file available from ATMEL
website.
See AVR Studio® on-line Help for information.
