I'm trying to setup OpenOCD 0.3.1 for debugging using an Olimex ARM-USB-TINY JTAG debugger and an Olimex LPC-E2468 development board. I start OpenOCD (version 0.3.1) with the following command: C:\Program Files\OpenOCD\0.3.1>openocd -f interface\olimex-jtag-tiny.cfg -f target\lpc2468.cfg It appears to start successfully and displays: Open On-Chip Debugger 0.3.1 (2009-11-13-16:13) $U

Does anyone understand exactly what the LPC-23XX Address Mirror bit 'M', in EMC Control Register (EMCControl) does?? LPC-23XX User Manual Rev.03, Chapter 5 table 60 says that when 'M' = 1 (after reset) "chip select 1 is mirrored to the chip select 0 memory area". Does this mean that accesses to CS0 address space activate CS1, and not CS0? That seems to me to suggest that there would be no CS0 ac...

Hello all, I am trying to program my lpc 2148 to generate timer0 interrupt. My development environment is Ububtu with gcc. After a lot of tweaking I tried the same sample on Keil on windows and the program worked fine. Complete details are here . Please let me know what's going wrong. Thanks in anticipation. Cheers!

There was a question in Keil forum about the max SPI speed that could be achieved using SSP in LPC1788 and a core clock of 120Mhz and based on the user manual the max speed for the SSP peripheral is core_clock/2 which gives 60MHz. Assuming that the PCB is designed to work fine with this speed, is this achievable from the MCU side? Is it possible for the output stage of the LPC to switc...

I have a problem with a LPC2468 board. I use Yargato on Eclipse and configured everything as in the description. I changed an example for LPC series to fit the LPC2468. (Amount of flash, ram and adresses) Compiling is without any errors. When I start the GDB, the segger console says: Reading all registers Read 4 bytes @ address 0x00000000 (Data = 0xE59FF018) Target endianess set to "little e...

Hi all. have question form different side. Is possible make easy end low cost MP3 player (mono, FM quality) with any LPC MCU??? is it possible. LPC2148 is possible to use (need 33kB ram and 110kB flash) but this MCU in min qty 1000> is not cheap. other MUC. now I test audio player with VLSI chip VS1000 (only ogg file play) work. but need external spi flash , and need external ADC (need this in

Hi everybody, I need some help. How can I crosscompile the libmodbus (libmodbus.org) for the lpc1768 ? Usually my code is wrote into CoIDE (from coocox) and compile with arm-none-eabi-gcc (with modification from Coocox). But I don't know how to do to have a static library usable. Any people can explain to me ?

I am using this Olimex LPC-2106 Dev. board. I can download and run the program demo2106_blink_ram from the ram. But when I try program the flash with the test program demo2106_blink_flash after checking for blank flash, it would show the blue progress line but would not blink the LED. I followed the steps below: 1.I powered up the board connected the rs232 cable to computer and the board, the sa...

Hi everybody, I try to use the Uart0 on my lpc1768, but after a lot of hours I can't obtain the correct baudrate. So communication is wrong. Some one have a simple example to explain me how I can do correctly? Here is extract of my codes and comments 1) First of all, in the main, I call the SystemInit function (writed by nxp team - file system_LPC17xx.c vs 1.03) where clock and perip...

I have a project that requires two 12-bit ADCs with parallel output and a sample rate of ~20-30 Msps. The micro will be processing the data into a bit stream, formatting that into a data packet and sending it out via a canned wifi solution. I could use an FPGA instead of a micro but it would add a lot of cost and time to the project. I could just try it with an LPC1769, 120MHz, FIQ, for exa...

Hello, I wish to migrate my legacy designs from 8051 to LPC 1768. I am not clear from the datasheet of LPC1768 what total current can I sink on port pins individually and collectively. Currently I can drive optocouplers like PC817 etc directly with 8051 port sinking more than 5 ma each pin. Shall I need to interface through some buffers like 74ACT245 or such to meet that requirement of current? R...

Hi Everybody, I have Olimex LPC-2478-STK board with 64MB SRAM. Using Uboot I'd like to run my whole application in the SDRAM. To achieve the goal, I did the following: 1. I modified my linker script- all sections go to the SDRAM, which is defined as: MEMORY { sdram (rwx) : org = 0xA0000000, len = 64M } 2. I remaped the program to external memory: MEMMAP = MEMMAP_MAP...
