    In addition to these three components, a JEDEC file is also necessary to program any Atmel ISP devices. This JEDEC file can be created by compiling a design file using a compiler software that supports the Atmel ISP devices. Atmel also provides translator software (POF2JED.EXE) to convert output files from the competitor’s programming for-...

    The TDI pin is the serial data input. It is used to shift programming data into the Atmel device. The TDO pin is the serial data output. It is used to shift out data from the Atmel device. The TMS pin is a mode select pin. It controls the state of the JTAG TAP controller.

  • Page 6: Multiple-Device Programming

    1.2.2 Multiple-device Atmel ISP devices can be configured as part of a JTAG daisy chain. Once the daisy Programming chain is configured, multiple Atmel ISP devices can be programmed at the same time (Parallel ISP).

  • Page 7: Design Considerations

    A device residing in any location in the JTAG chain can be programmed exclusive of all others. You can use the Atmel-ISP software to place all other devices except the one to be programmed in the JTAG Bypass mode. When the other devices are placed in this mode, a 1-bit flow-through register appears between the TDI and TDO pins for these devices.

    1. Double-click on the Device icon in the Sources section of the Project Naviga- tor. The Choose Device dialog box will open. 2. Click once on Atmel PLDs. Click on the down arrow to scroll through the device list. 3. Click once on the appropriate Atmel ISP device type to select the device for your design.
  • Page 9 If you have designs that prevent you from reserving resources for the JTAG interface or you do not wish to use ISP, you must select an Atmel non-ISP device type. See Table 1-2 below for a listing. You can then reprogram the device using an external device programmer.

    Atmel-ISP Package Options Atmel offers two options for customers who want to implement in-system programming. The Atmel-ISP kit is useful for customers who want to implement ISP on their circuit board. The Atmel-ISP board package is an in-system programming tool. The contents of each of these two options are listed below.

    This command allows you to create a new chain file. The chain file is ATMISP File Menu needed so that you can execute ISP operations for the Atmel ISP Commands device(s) in the JTAG chain on your circuit board or ISP board. After you execute this command, the ISP software will prompt you to spec- ify the number of devices in your JTAG chain.
  • Page 16 This option is intended to help you if you are having problems getting the Atmel-ISP software to communicate between your PC’s parallel port and either your circuit board or the Atmel-ISP board. When this option runs, the software dynamically adjusts the communication speed between the parallel port on your PC and the Atmel ISP devices in your JTAG chain.

    If there are discrepancies, use the Edit Device, Add Device or Delete Device command to modify the chain file. Atmel recommends that you view your chain file prior to executing it. This will assure that you are programming the right device with the right instruction in the correct order on your JTAG hardware chain.

Messages generated on-screen are further Messages classified into error messages, warning messages and notices. 7.1.1 Error Messages Failed to Save Chain File The software was unable to write the .chn file to disk.
  • Page 43 Another cause for this error occurs when the IDCODE box in the Atmel-ISP software JTAG Properties dialog box for each device is not checked. Versions 2.77 and later of the ISP software will warn you about this, but earlier versions may not.
  • Page 44 2. Problem: Your circuit board does not contain an Atmel ISP device(s). Solution: Make sure at least one Atmel ISP device is inserted in your circuit board. 3. Problem: No cable is connected between the PC’s parallel port and the 10-pin JTAG header on your circuit board.
  • Page 45 Solution: You need a different version of the ISP software (ATMISPNT) to be able to run on Windows NT 3.x and above. The Windows NT version of the Atmel-ISP software is also available on Atmel’s web site and BBS for download.
  • Page 46 The Atmel-ISP software reads an incorrect manufacturer silicon device ID for an Atmel ISP device on your circuit board. If any Atmel device has an invalid ID, you can still per- form ISP operations on it by using the hidden ID Check Override command. However, it is not recommended to override the device ID check feature.

  • Page 47: Warning Messages

    This error occurs if you have a 3V supply on your target system but are using 5V device(s) on your board. If the Atmel-ISP software detects a 3V supply on the JTAG header and a 5V device ID is read out from at least one device in your hardware chain, then it will generate this error.
  • Page 48 Troubleshooting The reverse is true for devices that have an ID code (such as Atmel ISP devices). The IDCODE box must be checked for them. If the IDCODE box is in the wrong state, it will affect the bitstream that the software actu- ally sees from your JTAG hardware chain versus the bitstream it expects to see.
