Compiling firmware with RVDS


#1

Does anybody know a good tutorial on how to compile firmware for the USBizi chipset (100 or 144) using RVDS?

I downloaded the trial RVDS, but I don’t know where to begin. I was looking briefly at the MCU’s loaded that you can target, but I couldn’t locate the NXP chip that is the USBizi.

Start with GCC, why RVDS? We have a book (still not complete) that explain porting. You can also take a look at the PK documentaion


#3

Why RVDS?

I’d like a smaller firmware size than GCC produces.

I’ll take a line out of your porting guide:

Yes but you are evaluating things not making production firmware right? :slight_smile:

If you own RVDS then yes for sure use that over GCC but if you do not then free GCC is pretty awesome!


#5

I’m evaluating something that could potentially become production. If I can’t get the development environment to be the same as production I wouldn’t be able to fairly evaluate the product.

Since we keep beating around the bush with RVDS, could you please just give me a comparison if you compiled the production USBizi firmware with GCC and RVDS? Exactly how much extra flash space do you gain compiling with RVDS versus GCC?

Thanks.

Sorry, I never tried this. You can try to ask Microsoft directly here http://www.netmf.com/Home.aspx
