USB bootloader for MCF5225x or MCF52223

Harjit — Sun, 08 Feb 2009 06:38:48 GMT

Hi.

A couple of days ago, I was surfing the freescale site and thought I had found source for the MCF5225x EVM or DEMOKIT or sample that had a USB boot loader that used the mass storage device model ala MCF51JM128.

I cannot for the life of me find it again.

Help!

Thanks,

Harjit

Hi Harjit,

Is what you are looking for on the 5225x DVD-ROM at:

D:\fscommand\MCF5225x_USB_BOOTLOADER.zip

This appears to be the subject of this lab tutorial:

For what it is worth, I run identical USB drivers on the 5225x, 52223, and 51JM128.

Hi Rich.

Yes, that is the app. note for which I am looking for the sources for.

I cannot believe I can't find them any longer.

Are you using the sources from the demo kit disk or are you using the sources you've had from when you started on the 522xx or?

The source is on the MCF5225X Family Getting Started DVD that came with my M52259DEMOKIT at the path I indicated.

Do you have that DVD?

I finally found the link: http://www.freescale.com/files/32bit/software/app_software/code_examples/MCF5225x_USB_BOOTLOADER.zip?fpsp=1

Rich, it appears to be the same as what is on the DVD.

Thanks.
