QUESTION

I am currently developing firmware for a custom AN2131QC-based application. I have been using the EZ-USB development board to test my application but now I need to port everything to the single-chip based application. How do I configure the tools to create a HEX file to download to INTERNAL RAM of the AN2131QC device?

ANSWER

To create a HEX file using µVision2, select the Create HEX File checkbox on the Output tab of the Options for Target dialog. You may open this dialog using Project Menu -> Options for Target.

To create a HEX file using the tools on the command line, you must run the OH51 program to create a HEX file from the absolute object file created by the linker.

Note that a HEX file is not what is typically used to download into the EZ-USB device. You may require a SYS file as described in the Infineaon/Cypress literature.

MORE INFORMATION

• Refer to Using OH51 in the OH51 User's Guide.
• Refer to Application Note 162 for details on programming the Cypress EZ-USB Board.
