Keil monitor and EZ-USB

The project requires the use of both uarts on the Cypress EZ-USB chip, so the monitor must use an extra, external uart, and a custom monitor is required. Unfortunately the monitor toolkit that comes with the Cypress Dev Kit is a little different to that supplied elsewhere. Has anyone out there in cyberspace done this job, I have a multitude of questions.

  • the monitor itself is almost the same. The only difference is the init.
    You may use the std mon51 from keil and modify the startup according to your needs. As far as I remember you will not be able to stop with external uarts, because you don't get serial interupts. With some disassembly even that can be done.
    The main trick will be how your monitor gets loaded with ezusb. You need carefully read the docs because Cypress will not help.

    A better way would be to use ISD51
