Posted on May 17, 2011 at 12:56I have written a program to write to external flash. I have written the code for STM32F103VB(100 pin) and since I don't have the actual board done yet, I am trying to run this on STM32SK using a IAR systems compiler and Jlink, JTAG. When i download my program it goes in a loop and i cant get out of it. When I break the program the cursor just goes to the disassembly code and does not break into my main program at all. I have tried to set breakpoints at my main function but it never comes to that point, seems like it gets stuck in some preprocessor directives?
I get errors saying the cstack is filled to 100% and CPU core is locked up. I have tried changing the stack value, increasing it from a default of 0x2000 to 0x20000 and it still wont work. I am not sure what seems to be the problem. I am aware that the GPIO or other peripherals do not have the exact same pin configurations but should it cause that huge an error to hang up the processor? Also I have tried running the example code to write to external flash, from ST->FWLIB->FSMC->NAND and the same problem occurs. But if I run a code for another dev board, like STM32F10E EVAL it partially runs( even if its not the same chip on the STM32SK), just doesn't configure the LCD, which is totally a different chip but it still runs.
I hope you guys understand my problem and can give me some tips.
Thanks!
