I'm working on uVision3 on a Cypress NX2LP-Flex board, and I'm getting the above message when I call a few, but not all of the I2C functions from the EZUSB library. For example when I just call EZUSB_InitI2C(), I'll get that warning. I've checked the Keil tech support articles and the closest I can see is at http://www.keil.com/support/docs/2316.htm and http://www.keil.com/support/docs/875.htm except this is an "uncalled segment" rather than an "uncalled function". The descriptions don't seem to match my case either...
Any ideas?
