Hello, I use IAR 4.41A with HJTAG v04.4. I can debug my code without any problem in RAM and I can program the flash and run the code but when I want to debug my code in FLASH the debugger stop at every branch instruction (B,BL,BLX,...) never go further. and when I press Step Into in Debug Log window I can see this error: ____________________________________________________________________ [RDI Error: 148] No more breakpoints left for this type of memory (RAM/ROM) Sat Aug 11 20:33:21 2007: Unable to execute: driver error. Sat Aug 11 20:33:22 2007: WinRDI Set break at address 0x00001340 failed ____________________________________________________________________ I don't use any breakpoint.so there is 2 breakpoint for IAR for debug. I test the IAR example on LPC2148 from olimex. Can anyone tell me where is the wrong? I'm really confuse. Thanks a lot.
