i update the uVision to the 2.31 versiona and the c51 compiler to the 7.01 version but I can't select the C8051f124 from cygnal and the web page I check and this chips is supported. what can I do? thanks
This device family is very new and it appears the device drivers for the Debugger does not yet support this device. However, you can get started by selecting the C8051F020 device. Make a copy of the c8051f020.h file found in the INC directory. Modify the .h file to include the SFRs of the 80c51f124. You can write and debug a lot of code with the default device. Also, contact Cygnal for an eval board if available. Cygnal has an add on .DLL that will allow real time debug via the JTAG interface to the uVision Deugger. Suggest that you contact Keil Support to see if a new driver will be available soon. Good Luck on your cutting edge project.
