| − | This page is currently under constructions, I'm doing this all over with the new versions of all the software
| + | - [[Mini2440 Linux]] |
| | + | - [[Mini2440 Openembedded]] |
| | + | - [[Mini2440 Windows Embedded CE 6.0 Trail]] |
| | + | - [[Mini2440 Qt]] |
| | + | - [[Mini2440 Boot from SD]] |
| | | | |
| − | == Toolchain ==
| + | tips and tricks: |
| − | First of all, we need a toolchain containing some command-line tools for our ARM platform:
| + | - [[Mini2440 Shifted screen problem]] |
| − | <ul>
| + | - [[Mini2440 MD5 checksum problems]] |
| − | <li>C and C++ compilers</li>
| |
| − | <li>assembler</li>
| |
| − | <li>linker</li>
| |
| − | <li>C and C++ runtime libraries</li>
| |
| − | <li>GNU debugger</li>
| |
| − | </ul>
| |
| − | <br>
| |
| − | I'm going to use the Sourcery G++ Lite ARM that is available for free.<br>
| |
| − | You can get the last version from http://www.codesourcery.com/sgpp/lite/arm/portal/subscription3053<br>
| |
| − | === Downloading and unpacking ===
| |
| − | <pre>
| |
| − | mkdir mini2440
| |
| − | cd mini2440
| |
| − | wget http://www.codesourcery.com/sgpp/lite/arm/portal/package5353/public/arm-none-eabi/arm-2009q3-68-arm-none-eabi-i686-pc-linux-gnu.tar.bz2
| |
| − | tar jxf arm-2009q3-68-arm-none-eabi-i686-pc-linux-gnu.tar.bz2
| |
| − | export PATH=/home/ttts/mini2440/arm-2008q3/bin:$PATH
| |
| − | </pre>
| |
| − | The last line will add the bin directory the $PATH variable so that we can use the commands in that directory like normal commands.<br>
| |
| − | Every time you open a terminal, you have to enter that last line. (or you can add it to your .bashrc file)
| |
| − | | |
| − | == Uboot ==
| |
| − | === Download uboot for mini2440 ===
| |
| − | <pre>
| |
| − | mkdir uboot
| |
| − | cd uboot
| |
| − | git clone git://repo.or.cz/u-boot-openmoko/mini2440.git
| |
| − | </pre>
| |
| − | | |
| − | === Compile uboot ===
| |
| − | <pre>
| |
| − | export CROSS_COMPILE=arm-none-eabi-
| |
| − | cd mini2440
| |
| − | make mini2440_config
| |
| − | make all
| |
| − | </pre>
| |
| − | When I tried to compile uboot I got an error about some weak declarations in lib_arm/board.c and common/main.c<br>
| |
| − | I'm using the 4.4.x gcc, and the 4.3.x does not cause that error. You can downgrade your gcc or remove the "weak" definitions in those files like I did
| |
| − | | |
| − | === Compile upload tool ===
| |
| − | <pre>
| |
| − | cd ~/mini2440
| |
| − | wget http://mini2440.googlecode.com/files/s3c2410_boot_usb-20060807.tar.bz2
| |
| − | tar jxf s3c2410_boot_usb-20060807.tar.bz2
| |
| − | cd s3c2410_boot_usb
| |
| − | make
| |
| − | </pre>
| |
| − | When make fails because he can not find the file "usb.h" install the ubuntu/debian package libusb-dev.
| |
| − | | |
| − | === Upload the file ===
| |
| − | Open a terminal to the serial connection of the mini2440 board.<br>
| |
| − | Put the NOR switch to NOR and power the board.<br>
| |
| − | Now you get a "FriendlyARM BIOS"/supervivi menu, choose q to go to the supervivi shell.<br>
| |
| − | In this shell you typ "load flash 0 232188 u"<br>
| |
| − | Where "232188" is the size of the uboot.bin file you are going to send. (ls -la mini2240/uboot/mini2440 | grep u-boot.bin)<br>
| |
| − | Send the file from your linux terminal:
| |
| − | <pre>
| |
| − | ./s3c2410_boot_usb ../uboot/u-boot.bin
| |
| − | </pre>
| |
| − | Sometimes the upload tool says that the upload is failed, but don't trust it :P<br>
| |
| − | The upload of uboot didn't work for my at first but just keep trying
| |
