We are currently developing an 8051 based project using the PK51 Development Kit and are going to move to an ARM based system probably using the MDK-ARM Development Kit. My question is, since they both use uVision4, will they coexist on the same PC? Is there anything special that needs to be done for them to coexist? My expectation is that they are completely independent packages that both use uVision and will peacefully coexist but I don't want to be surprised.
They will share uVision but the architecture-specific part will reside in separate directory trees.
Under c:\Keil you will still have a directory UV4, but will also get a directory ARM.
And the file c:\Keil\TOOLS.INI will get sections relating to ARM.
OK, I went ahead and downloaded the demo version of PK51 to the PC that had the demo MDK-ARM and it told me that I had a newer version of uVision and asked which I wanted. It added a C51 subdirectory to C:/Keil and also added a C51 section to the TOOLS.ini file. So all looks well at this point. Thanks for the quick response.
