Hi everyone
Playing around with such a board in order to get aquantaint with ARM-Cortex (I've also used LPC2129, LPC2103, etc.) my program crashes whenever I enable the next option (in "driver_config.h" file):
[FONT=Courier New]CONFIG_ENABLE_DRIVER_PRINTF 1[/FONT]
The project is very simple, I just followed the instruction for starting a fresh "template" one. If I disable that option the program runs (led blinks); if I don't, then the program is catch with that exception. I copied for you the stack, so it may help:
[FONT=Courier New]Thread [1] (Suspended: Signal 'SIGSTOP' received. Description: Stopped (signal).)
7 HardFault_Handler() cr_startup_lpc11.c:338 0x000001e0
6 <signal handler called>() 0xfffffff9
5 <symbol is not available> 0x1000002c
4 _fdopen() 0x00000a82
3 _initio() 0x000009c2
2 __main() 0x00000978
1 ResetISR() cr_startup_lpc11.c:313 0x000001ca[/FONT]
Maybe I need to set some other option in order printf() to work. Also I guess this is the CMSIS release I've attached to the project:
[FONT=Courier New]* @file core_cm0.h
* @brief CMSIS Cortex-M0 Core Peripheral Access Layer Header File
* @version V1.30
* @date 30. October 2009[/FONT]
Any help would be very appreciated, and thank you in advanced. Kind regards.
Javier
