Change for F28027F ROM

Toby,

To be clear you want to use the F28027F launchpad as a normal F28027 launchpad, correct?

I believe ALL of the ROM contents are different between the two devices. I am confirming if anything remains (perhaps the Flash API...not sure on the Device_cal() function).  I know for sure that IQMath is removed from F28027, so if a software example uses it you must add to your project in user memory.

Hi Chris

Yes exactly, I would like to use the F28027F as a normal F28027.

From TI code I think we use Device_cal(), MemCopy() [ramfuncs section, e.g. LOAD_START, LOAD_END, etc], IQ Math Tables, digital power lib [CNTL, PWM, ADC], Sine tables (+ we will be adding Sine Analyzer from the solar power lib as well). I'm not 100% sure which of these use data from the normal ROM.

Our CMD file has the following:

As I mentioned, although this seems to mention all the things we need, I'm not sure if this is sufficient to have all that we need added... ?

Thanks

Attached is a consolidated Symbols file...this will work for doing "non InstaSPIN" software on an F28027F or F28026F.

You should link in the IQMath.lib to your project.

You must FORCE the linker to link this symbol file before IQmath.lib:
(here we are including the Fast symbols / .lib as well...proving we could still run our InstaSPIN projects)

All functions are in boot rom, even though IQmath.lib is added to your project. For any additional IQmath functions added to the project - if they are not in boot rom -  it will get it from IQmath.lib (ONLY the ones that aren’t in boot rom already).
