Hi All, I'm in my last year of Electronics Engineering, and am doing a project on VoIP using ARM. My group and I are currently looking for ARM boards, and have recently shifted focus from ARM9 to ARM7 for want of money. Can I port RT- or Embedded Linux on ARM7TDMI(the one architecture easily available in India)? What're the requirements? Awaiting answers, Thanks.

I'm using a Sharp LH79524 ARM7 microcontoller along with the IAR compiler and Segger's J-link. I was developing my program yesterday and it downloaded to the target and ran fine but this morning I have downloaded it and it gets stuck on the data abort exception. This happened with the project I did on Wednesday and I never managed to get it to load again. Both projects are based on a sma...

Hello, I am currently using a 68331 CPU in a existing design and I am thinking about it if it is really necessary to change the CPU. Possible successor are Coldfire or ARM7. The reason why I want to stay is that I could cut down on development time and focus on application requirements. Reasons for upgrades are computational resources, power requirements and price. All of them are solvab...

Hi all, Sorry about my newbe question, but I'm lost trying to figure out how to do that.... I'm expert in ARM7 design but aways using comential IDEs (not so expert). Now I'm working in a new project using an ARM966E-S core. And my intention is to use the GCC to generate de code (I never use it before). First of all: is it good or should I run from it (gcc)? Second: in the GCC docum...

hi, Heres a completely novel question : which ARM9 chip ? ;) Ok, just kidding. What i am really looking for is a bit of advice amongst my fairly limited choices. First, i need a chip for an application, that is as integrated as possible ( who doesnt ? ) and the app needs Ethernet, ARM9 > 100mhz ( i really wish i could run on ARM7 but i cant ) and an LCD. Seems like an easy task, but a

Hi, Please guide me to the right group(s) if the post isn't on topic here. My program is running on a ARM7 h/w on top of an RTOS. I want to dump the names of the functions that were called in the sequence they were called (stack) onto a file as part of the assert routine. Something like a core dump in *nix. How to implement something like this? Where do I need to look? Regards Sukrit...

As we mentioned previously, we are working on a version of our C compiler for the ARM chips, initially for the ARM7 microcontrollers (more devices supported later). Anyway, our assembler / linker and even the code generator are progressing well, and we are at the stage where we can use a good simulator or debugger to start debugging our tools. Currently, we are using evaluation version ...

I am designing a board using a Philips LPC2114 (nice chip). It uses 1.8v for the core, 3.3v for I/O, and I also need 5v for some other circuits on the board. None of them use much current. The power supply is a 12v battery. What is the best way to get these voltages, without running down the battery? Is there a single device, such as a DC/DC converter that can produce these voltages? ...

Hello group, After years of development on various windows CE platforms, I am now tasked with developing software for a new Atmel ARM7 based design. We plan to use a serial SPI flash for datastorage, but I lack a little understanding. We need to handle about 2MBytes of sessiondata and systemconfig data and we need to be able to dump and modify these data on a PC via ethernet link. Also the...

Hi all, Anyone that has experience with some of the lower cost IDE's bassed on the GCC? We have been looking at: http://www.rowley.co.uk/arm/index.htm We seriously considers to buy this instead of the way more expensive products from IAR, KEIL...etc. We develop applications of a med. complexity. Any comments on this choice ? Best Regards -- Morten Jorgensen, IA data. http:...

Hello, Could someone point me to something that could help me creating/understanding GUI for embedded systems in general? What's the "easier" (I know "easy" could be relative) to get GUI on an embedded system? The hardware I'm looking for is ARM-based microcontrollers (Cortex M3, ARM7 or ARM9). I think Qt could be a solution right? However I would like to know "lighter" alternatives. T...

I've wasted a couple of days trying to get timer 2 to IRQ through the Vectored Interrupt Controller (VIC) - it always ends up in the default handler. If anyone has an example C or assembler snippet you'd bring a little light into a frustrated programmers miserable life. I'm actually using a development kit called CardEngine by logicpd and the message their loader squirts out is "NO HANDL...

Hi! I am building a simple monitoring system, that would read data from few sensors and display them on a colour 320x240 LCD. As far as the microcontroller goes, I'll probably go with ARM9 or ARM7. Do you have any suggestions about the development board and LCD. I've been looking at Densitron, but they don't offer LCDs with built-in controllers. I've also looked at NXP LH7952x but I can't seem ...

Hello group, I'm curently trying to get familiar with the ARM7 by building some example-projects for a LPC2106-controller. One such project is the blinky_irq example from Keil which should demonstrate the use of interrupts and of the LPC2xxx vectored interrupt controller. I'm using gcc-3.2.1 with binutils 3.13.1 and newlib 1.11.0 . So far I had no problems with these tools and I was abl...

Hi, I am using ARM Developer Suite by Codewarrior on Hynix processor with an ARM7 core. I want to configure size of few datatypes. e.g.: I want to configure the size of char as 2 or 4 accordingly. Is it possible using the complier features? I was unable to find anything in the complier menu. Kindly guide me through this. Regards RahulS

I have a design based around a Z8 Encore which is soon to grow beyond the capabilities of the Z8. Several of our other products are based around Intel 80188 microcontrollers and it was initially thought that this would be a good route to upgrade seeing as we already have the tools and knowledge. However, I also have tools for ARM based processors and knowledge there too so I thought i...
