  • Page 31: On-Chip Debugging

    The Atmel AVR ONE! is not a traditional Emulator. Instead, the AVR ONE! interfaces with the internal On- chip Debug system inside the target Atmel AVR device, providing a mechanism for monitoring and controlling its execution.

  • Page 32: Jtag

    The JTAG interface consists of a 4-wire Test Access Port (TAP) controller that is compliant with the IEEE 1149.1 standard. The IEEE standard was developed to provide an industry-standard way to efficiently test circuit board connectivity (Boundary Scan). Atmel AVR devices have extended this functionality to include full Programming and On-Chip Debugging support.

    6.2.5. debugWIRE The debugWIRE interface was developed by Atmel for use on low pin-count devices. Unlike the JTAG interface which uses four pins, debugWIRE makes use of just a single pin (RESET) for bi-directional half- duplex asynchronous communication with the debugger tool.

  • Page 40: Architecture Description

    Power is supplied via the 12V DC connector. The USB port is used for host communications only, and does not draw current from the host. At the heart of the Atmel AVR ONE! main-board is the ATmega1280 AVR microcontroller, which is coupled to an FPGA for target interface signal processing. The target interface is clocked by an external clock generator capable of providing a frequency in the range of approximately 1kHz to 64MHz.

The command line utility is installed in the Atmel Studio installation path in the folder Atmel/Atmel Studio 7.0/atbackend/.

  • Page 44: Advanced Debugging Techniques

    The OCD debugger makes use of the memory mapped OCDR register to access the internals of the Atmel AVR target device while it is in stopped mode. When in run mode, the application running on the target can write a value to this register. The OCD system will then signal this to the debugger, which then fetches the data and passes it to the GUI front-end, where it is displayed.

  • Page 45: Debugwire Targets

    Instead, the debugger must make use of the Atmel AVR BREAK instruction. This instruction can be placed in FLASH, and when it is loaded for execution it will cause the AVR CPU to enter stopped mode.

  • Page 46: Special Considerations

    • One data breakpoint with address range, value range or both Atmel Studio will tell you if the breakpoint can't be set, and why. Data breakpoints have priority over program breakpoints, if software breakpoints are available. External reset and PDI physical The PDI physical interface uses the reset line as clock.

  • Page 47: Atmel Megaavr Ocd And Debugwire Ocd

    Accessing 16-bit Registers The Atmel AVR peripherals typically contain several 16-bit registers that can be accessed via the 8-bit data bus (e.g.: TCNTn of a 16-bit timer). The 16-bit register must be byte accessed using two read or write operations.

    JTD bit. This will render code un-debuggable, and should not be done when attempting a debug session. If such code is already executing on the Atmel AVR device when starting a debug session, the Atmel AVR ONE! will assert the /RESET line while connecting. If this line is wired correctly, it will force the target AVR device into reset, thereby allowing a JTAG connection.

  • Page 49: Debugwire Ocd

    Alternately, use the debugWIRE interface itself to temporarily disable itself, which will allow SPI programming to take place, provided that the SPIEN fuse is set. Note:  If the SPIEN fuse was NOT left programmed, Atmel Studio will not be able to complete this operation, and high-voltage programming must be used.

  • Page 50: Atmel Avr Uc3 Ocd

    Atmel AVR UC3 OCD On some Atmel AVR UC3 devices the JTAG port is not enabled by default. When using these devices it is essential to connect the RESET line so that the Atmel AVR ONE! can enable the JTAG interface.

    12.1. Self-test The Atmel AVR ONE! is shipped with a self-test adapter with an IDC cable. If it for any reason is suspected that the AVR ONE! cable and probe are not functioning correctly, a self-test can be run. The self-test adapter is a loopback adapter that enables the on-board MCU to perform diagnostics on the target communication circuitry.
