Debug with Keil uVision2(evaluation version for cypress development kits) I design my new system with cypress USB 100pins 68013. no external RAM. Now, I download C:\Cypress\USB\Target\Monitor\mon-int-sio0.hex to 68013 via EZ-USB control panel. I set uVision 2 "Options for Target"->BL51 Locate-> Code Range : 0x4000-0x7fff. Then I can use uVision download the code, but debug still not work. it seems the code jump to somewhere but not main() Then,I set uVision 2 "Options for Target"->BL51 Locate-> Code Range : 0x4000-0x7fff. for the assembly code. I found I can debug assembely code correctly. but I still cannot debug code in C. I wonder if the Keil cannot support C language when I set Code Range : 0x4000-0x7fff or maybe I have a wrong setting for this software. Could you help me?
