We have used your demo hardware DRV8301-69M-Kit (D) together with Motorware 1.01.00.16.
Now we only want to use your instaSPIN FOC and not Motion. Therefore we use the TMS320F28062FPZT instead of the ..28069M.
We exchange the cmd files (F28062F_ram_lnk.cmd and F28062F.cmd as well as TMS320F28062_xds100v2.ccxml) and the Motor is running at this moment.....
The problem is about the following: The handle returned by CTRL_initCtrl is 0x00013C40 on the 28062F (as well as the 28069M).
With the 28069M there is RAM at this location, but not with the 28062F !!!!!
- Is the internal RAM area, used for InstaSPIN FAST FOC, internally at the 28062F from 0x13800 to 0x14000 undocumented available? (Datasheet says: there is no RAM!)
- Or is it mirrored from the normal RAM range 0x008000- 0x00E000 of the 28062F? (a big problem, if we use this ram for other applications)
- Or is this a bug in the internal FOC-Lib in ROM?
- When using InstaSPIN FAST FOC, do we have to make changes to the project settings in the Code Composer or the CMD files?
Thanks for help.
