I'm new to the LPC world and I'm trying to bring up the gnuarm toolchain with the newlib-lpc release 5a port from http://www.aeolusdevelopment.com/Articles/download.html . I'm running Ubuntu linux and I'm having issues with compiler and newlib base version compatibility. My test is to build load and run the test10.c program on an OLiMEX LPC-P212x development board. If I build the followi...

Hi all, I am using LPC2364 with FreeRTOS,GNUARM. Issue: I have Set RTC Alarm to one minute.After setting RTC suddenly,My program hanging(after task_exit critical()).But in LPC2103 its working.Which means getting RTC alarm interrupt after one minute.Is there any different between LPC21xx and 23xx RTC Setting.Please share your knowledge??? Interrupt priority only differs betwe...

I finally got OpenOCD to work with my lpc2148 board from Olimex, or at least I think i have it working. I am using an ubuntu 10.10 machine to do my programming with their (packaged) version of openOCD. I had to go get the GNU Arm programs. http://www.gnuarm.com/bu-2.16.1_gcc-4.0.2-c-c++_nl-1.14.0_gi-6.4_x86-64.tar.bz2 I even got the olimex files for my board: http://www.olimex.com/dev/soft/arm/LPC...

Hi everybody, I'm debugging my LPC2378 project in Eclipse (GNUARM, OpenOCD, GDB toolchain), and I don't see a way to view the various chip peripheral registers (FIO0PIN, TOIR, U0THR, etc) symbolically. I can only view them using the memory dump window by specifying the register's address, which is sort of clunky. I can view registers r0-15 just fine in the register window. Is there a way to ...

I am having trouble getting the interrupt to work when data is received on UART0. I have verified that the UART is working, both sending an receiving. I am using GNUARM, any pointers would be great. //main.c #include #include "lpc2103.h" #include "uart.h" char data; unsigned char test = 0; void UNDEF_Routine(); void SWI_Routine(); void IRQ_Routine()__attribute__ ((inter

Hi I m using GCC GNUARM version 4 in linux for LPC-2119 processor.The program is getting compiled but the ISR is not getting called. The program is pretty simple,shown below : #include"LPC21xx.h" void init_pll() { PLLCFG=0x40; PLLCON=0x01; PLLFEED=0xAA; PLLFEED=0x55; while(!(PLLSTAT & 0x400)) {} PLLCON=0x03; PLLFEED=0xAA; PLLFEED=0x55; VPBDIV=...

Hi all, I'm a total newbee on the ARM platform. I got the Embedded Artists LPC2103 educational board when I got their seasonal Christmas Tree LPC2103 based board. I am at sea here and would like an "arm" up (sorry, I couldn't resist it.) My platform of choice is the Mac OS X 10.4 and 10.5 system running Eclipse Europa and the GNUARM Eclipse plugin. After I installed the plugin, w...

Hi all, I am using printf() functions with FreeRTOS,GNUARM.When i use printf() function, code size increased to 12k.Which means printf() related lib functions used this much memory.But in keil lib, this much code is not used when i used printf() function. Questions: 1.Is there anyway to reduce this much code memory by setting compiler option in Makefile? 2.or Is this is limita...
