anyone? I posted a couple messages last week and no responses. Summarizing, I can compile, link, and download the bin/hex onto the lpc2148. All examples work, until I use math functions. My simple test is to simply calculate sin(PI) and dump to uart. Any hints? help? ------------------------------------

Hi all, I know it's been here several times before buts o far i could not fin dan answer. I was wondering if there's some sample code for setting up a USB HID in the LPC2468. perhaps that NXP has some code not yet published?? What I'd like to do is set the lpc as a generic hid device using USB_D1 (P0.30 and P0.29) I've already played with the lpc2148 works fine, but the lpc2468 is somet...

Hi, I want to know how to compile programs written in C and in assembly on Linux based host system. I don't want to use linux on my microcontroller. I saw that uClibc document. It seems that this library is for compiling software for ARM microcontroller running Linux on it. Say I just want to assemble the instruction: MOV R0, #10H And say I just want to compile the program: main() { in...

I'm thinking of getting a developement board for either LPC2478 or LPC 2468. I just have a few questions regarding a bootloader. 1. Is it possible to completely remove the Phillips boot loader and just use my own? 2. If not, Do I have to jump to sections of the phillips bootloader in order to write to flash, or can my bootloader be completely independant? 3. What are some good refer...

Hi everyone, I am using an LPC2103, compiler IAR EW. While it is easy to get the polled version of UART0 communication to work, I can't get the interrupt based version to work. Can anyone point me to an example on how to initialize a simple interrupt based communication via UART0/1 using IAR EW for an LPC 2103? Or froma similar controller? Thanks a lot, Tappo ----------------------...

I have been trying to get a USB secondary boot loader to work on my Olimex LPC-P2378 using CrossWorks tools. Since I am new to debugging USB and fairly new to CrossWorks I have been going in circles. Anyone know of a USB Bootloader for the LPC2378 that builds under CrossWorks? ------------------------------------

Hi!! I'm using lpc2378 and I have a problem with can bus. Sometimes happends that CAN bus is locked. I thought this happend because of lpc bug - "In a Data Overrun condition, the CAN controller is locked from further message reception", but I monitor this with IRQ and this in not a reason. I notice that I have a lot of Receive errors (I get IRQ Error Status). How to control, if it's lo...

Hi Does anyone use LPC2366 Rev 'B' and Micrel KS8721BL/SL PHY? I would need some sample code to test if I have problems with my custom built PCB or if I missed something while porting the FreeRTOS 2368 demo to my board. I have changed flash size in linker script to 244K (why does FreeRTOS demo declare 12K less flash that lpc has?), changed PHY ID for Micrel PHY and set IP address for my ...

Hi, I am (so far) using mostly J.C. Wren's code to run small applications on an LPC2148 board. Turns out I don't need USB that much after all, so I play with LPC2103 now using the FreeRTOS ARM7_LPC2106_GCC example. I use gcc, so that's all fine. And then I thought: would it not be nice to have one header file which include all LPC members (or at least a family like LPC21xx), so that com...

Well, on my Olimex LPC-2378-STK board, I've seen similar messages after I fed OpenOCD a configuration for another board. I had downloaded a project for another board and was converting it to run. After trying to upload to the wrong locations, it started spewing messages like yours. Resetting everythi

Hi All I wonder whether someone has a fast answer to this? Board is Olimex LPC-2378-STK (but board probably not the problem). After a power on the SW runs correctly (100% reliable after many tests). After a push button reset the software often runs correctly, but not always. When it doesn't run correctly it is because no interrupts are operating. Some details: - when the SW is reset ...

Hi all, I have an Olimex LPC-2378-STK board. I am completely new in the ARM world. I have installed the following development environment on Windows XP: yagarto (gcc 4.2.1), openocd (r717). I don't use Eclipse. To program the board I have bought an ARM-USB-OCD tool. I have successfully compiled the simple LED blinking program (from http://olimex.com/dev/soft/arm/OpenOCD-projects100.zip...

What are all the tricks to get the lpc21isp (v1.48) utility to actually work? I have the EA LPC2478 board. I have a ulink and flashmagic, but I'd like to know all the options for burning code. I finally figured out that the lpc util does not control the state of RST and P2.10 like flashmagic does, so I have learned to press the two related buttons on the board as needed. When I try: >
