Programming with AVR JTAG ICE
To program the device using ISP from STK500, connect the 6-wire cable between the
ISP6PIN connector of the STK500 board and the ISP connector of the STK525 as
shown in Figure 2-18.
Note:
Note:
The AT90USBxxx can be programmed using specific JTAG link. This sub-section will
explain how to connect and use the AVR JTAG ICE.
Note:
Figure 2-21 . Connecting AVR JTAG ICE to STK525
The Flash, EEPROM and all Fuse and Lock Bit options ISP-programmable can be
programmed individually or with the sequential automatic programming option.
Note:
See AVR Studio® on-line Help for information.
The high voltage parallel programming mode with STK500 is not available for an
STK525. To reprogram an AT90USBxxx part in parallel mode, use an STK501 extension
board (AT90USBxxx product pinout is compatible with the STK501 parallel programing
mode).
When the JTAGEN Fuse is unprogrammed, the four TAP pins are normal port pins, and
the TAP controller is in reset. When programmed, the input TAP signals are internally
pulled high and the JTAG is enabled for Boundary-scan and programming. The
AT90USBxxx device is shipped with this fuse programmed.
