Hi, I'm greatly impressed by the mini2440. I'm looking forward to buying one arround next week. So far I've been looking at the source code on this page. A friend already has a mini2440 and we were playing with the mini2440test image. Its astonishing fast and I love it. But the source code supplies a CodeWarrior project file. Is there a problem compiling this code using gcc? Has anyone tried that yet? Thanks for your advices :)
I've just looked arround and see that there is no real chance of compiling this without ADS1.2 :(. Very sad. Not sad that there actually IS a way to get it working, I just dont know enough about the whole architecture yet. We simply have to get it to link the application to the right entry point so the 2440 can boot it. That is done by an ASM bootstrap. Anyone with me :)?
Hi Guy's has any one found a way to compile the tests and bootloading using gcc ? some more questions 1. where can I get an evaluation of ADSv1.2 OR better yet codeWarrior for ARM Developer suite v1.2 2. does it work with any other IDE\Dev Suite ? Thanks
Hey looks like you're stuck there too. Well I was able to acquire a copy of ADS1.2 and had luck compiling the 2440test with it. Wasnt able to compile with anything else yet. The problem is NOT the C code basically but the ASM code! I think you have to port that to get it working :(
Hi Jazz, Thanks for the fast replay good to know I"m not alone :) can you please give me a site for downloading ADS 1.2 do u know how I can get an Evaluation version ? Thanks Benny.C
I downloaded ADS1.2 from here http://www.mcu123.com/down/view.asp?id=39 Regards!
Hi, By the way, did someone found some (even primitive but working) project example(with startup.s, makefile) for s3c2440 that can be compiled using gcc? BR, Damian
Hello Damian Eppel, Actully I am also working on ADS1.2 and I have developed apllication on ADS1.2 which works fine in RAM but same thing when downloaded into NAND my application hangs up in middle itself. Do you have any solution to this... Regards sam
Dear Phil, Thanks lot I have gone through 2440init.s file not getting where to modify in order to make my application to work successfully. If you have any idea plz. help me.
Just want to say thanks for the link to ADS 1.2 - downloading now. Was pulling my hair out looking for it!! Here is the ADS 1.2 IDE user guide (found it looking for ADS 1.2) just in case someone is looking for that too.. http://infocenter.arm.com/help/topic/com.arm.doc.dui0065d/DUI0065.pdf
I visited the link but could find the link to download http://www.mcu123.com/down/view.asp?id=39
Simple trick to find the download link: Move slowly over the web page with the moouse. Where the cursor turns into a hyperlink-hand, look for "down" in status line at bottom. There you go :-)
I am having difficulty on chosing the coding platform for arm9 mini2440.i downloaded Real Arm Development Suite.But unable to run a simple I/O or led code....Can any 1 help me by providing simple step by step...of any platform for mini2440.. thanks
Hi! Download an ARM toolchain from here http://www.codesourcery.com/sgpp/lite/arm/portal/subscription?@template=.... You can choose from compiling to linux(GNU/Linux) or to bare metal(EABI). Mini2440 comes with linux. Under linux, after you downloaded the toolchain you can compile sources with "toolchain_directory/bin/arm-none-***-gcc" where *** could be "linux-gnueabi" or "eabi" depending what you chose at download stage. Some useful flags for gcc when compiling to mini2440: "-msoft-float -mcpu=arm920t -mtune=arm920t -march=armv4t" Sharp
hi JazzD, i am new to this coding stuff.. i have got one mini2440 but am not able to compile even a simple code in mini2440. The ADS 1.2 you are talking about needs to be installed on my mini2440 or on my linux PC. Is it tht if i install it on my PC i only need to take the executable file on board and run it there. Plz reply soon. I am in dire need of some help! Thanks in Advance regards ankit

You can found they in download section on this site. There are source code for the u-boot, vboot and vivi. All of them using GCC for compiling (as far as I understand). vboot source code very simple for understanding... I am have similar problem, but I try to find sample project for the IAR EWARM... Unsuccessfully... :-( So I am spend five interesting evenings to try create my own application for the mini2440. Successfully :-) First example that simply playing with LED's I am compile very fast, and they work well. But I am need interrupts processing and ability to run my program from NAND, so it is was very funny to learn by myself step by step how to do this, including reading a lot of documentation, learning bootloaders source code, reverse engineering and many other pretty things... ;-D (I am was not very friendly with ARM previous) But now I am understand enough in how S3C2440 works and in IAR specific compilers things :-) PS: Sorry for my English.
Dear Vladimir, please share your example project. I am having troubles to start with IAR Embedded Workbench for ARM. I think your help could be precious to me and a lot of other people too. Thank you in advance, Aci
Hi Vladimir, Can you share a couple of the simple projects you did on MINI2440? That would be a big help for the beginner developer like me. Did you compile the code using IAR EWARM? Thanks
If anyone is still interested in 2440test ported to IAR, here's a snapshot of my current effort: http://www.filedropper.com/2440testiar There are changes to the original 2440test source code, some to comply with the IAR syntax, some to correct actual errors. The project compiles in IAR EWARM 6.21 kickstart (32k code limit), when optimization is set to max and space. The linker config file mini2440.icf places everything in SDRAM. To download it, set the mini2440 into NOR boot, start H-JTAG and make sure it detects the ARM920T core, then hit the download button in IAR (you may need to change the location of the H-JTAG driver in RDI setup). Items known not to work: 1. ARM-Thumb interwork, mainly for the ARM assembly functions. The compiler is set up to generate ARM code only. Thumb will not work. 2. USB functionality? I'm still new to the 2440test code and I'm not sure what the USB functionality is supposed to be. Is there even any documentation for this? All the menu items through the serial port seem to work properly, though. Gene
Hi guys, I would first like to apologize for my bad English... I'm an ARM beginner and would like to learn with mini2440. I downloaded 2440test 2011-04-21 and I tried to compile 2440test with ADS 1.2 (open the 2440test.mcp and F5 - Debug), but it has 12 errors and 76 warnings... errors are like: "Undefined symbol __rt_udiv (referred from 2440lib.o)." "Undefined symbol _dflt (referred from 2440lib.o)." "Undefined symbol _dmul (referred from 2440lib.o)." etc. (all is about 2440lib.o) (on Windows 7 Professional x64) What I'm doing bad? Thanks for helps!
Hi again, I solved this problem itself. Problem was the installation of ADS, it must not be installed under "Program Files" path under Win7. Perhaps it will help someone...
Hi Gene your link do not work. Can you send a new one? Many tanks!
The same problem with tiny210... I'm tried Iar ARM 6.3 6.5 and keil 4. Jetlink detecs core, but source files do not run. Now i'm downloading ARM Development Studio 5 my core is supported.
