I have installed SiC8051F_uVision, but the EFM8BB50 series microcontroller is not listed in Silicon Labs' database. How can I compile EFM8BB50 with Keil? If I have all the header files for this microcontroller, can I create a database for it and compile it myself?

In the meantime, since I've never heard of the "SiC8051_uVision" variant (my install is much older), can you please post from your uVision menu Help -> About uVision?
