Using GNU GCC in Keil uVision - why?

This has been a frequent question recently, and the frequently-given answer is:

GNU support in uVision is now available via CodeSourcery. See: http://www.keil.com/appnotes/docs/apnt_199.asp

See:
http://www.keil.com/forum/docs/thread12535.asp
http://www.keil.com/forum/docs/thread12663.asp
http://www.keil.com/forum/docs/thread12720.asp
etc, etc...

My question is: if you've got Codesourcery - which includes a complete toolchain, IDE, debugger, etc - why would you also want uVision?

  • Hi,

    As you said above, simulation in Keil eval version has problem with peripheral simulation (startup.s is an example).
    So, when I simulate the code segment of LPC2300.s file below. It can't jumb to Reset Addr. It only run sequentialy to the NOP and get stuck. Is it that problem ?

    Vectors         LDR     PC, Reset_Addr
                    LDR     PC, Undef_Addr
                    LDR     PC, SWI_Addr
                    LDR     PC, PAbt_Addr
                    LDR     PC, DAbt_Addr

                    LDR     PC, FIQ_Addr
