Making a minimalist BSP

[Darkn3ss]

Hi, I've been learning MQX for about two weeks now when I have the time to work with a demo board.

My hardware designer is designing a board for me to use, and working on a custom BSP for it, there is a ton of the canned code that I would like to just eliminate, and then initialize what I want into MQX as I want it and have more control over the hardware.

Has anyone else tried doing the same and having really just a minimalist BSP where it is really just MQX itself, and all of the peripheral initializations are done by the programmer?

Thanks.

Hi

Sorry I dont have an answer for your question, but I was also interested in how small a basic MQX image is with the configuration options removing most of the additional functionality.

I am specifiially interested in what is the minimum size of an MQX image that contails just a USB host function. I am contemplating using that to make a boot loader that can update an APP from a usb memory stick. Anyone hazard a quess at what a V2 52259 image size could be crunched down too ?

Geoff,

There is no need to run MQX for your boot loader, you can simply boot to your own code, then boot MQX (start with the MQX file vectors.c, you will see where to call your boot loader function)

This way you can use the USB example code (none MQX based). If you like I can email you an old version that someone else posted a while back, just drop me an email and I will reply with the code carl@edsengineering.com.au
