EPM900: IAP, ISP Support for EPM900

Information in this article applies to:

• EPM900 all versions

QUESTION

Does the EPM900 support IAP and ISP applications?

ANSWER

The IAP and ISP functions are not supported on the bond out chip for the EPM900. The reason for this is that the emulator's start-up code resides in the Flash and the user code is emulated out of external RAM. If the IAP functions were available in the bond-out then the customer could potentially rewrite or erase parts of the emulator start-up code, making the EPM900 non-functional.

You may verify IAP functionality by flashing the program to an LPC932 and using the Keil monitor to debug the code.

• Refer to Supported Devices in the EPM900 User's Guide.
