    <p>I'm trying to get started with the STM32 (Cortex-M3) and my plan is get this working from Ubuntu (9.04 / AMD64). </p> <p>To start with I got the <a href="http://olimex.com/dev/stm32-h103.html" rel="noreferrer">Olimex stm32-h103</a> header board and the <a href="http://olimex.com/dev/arm-usb-ocd.html" rel="noreferrer">Olimex ARM-USB-OCD</a> jtag, and on to of that I will probably use OpenOCD, gcc and Eclipse.</p> <p>But right now I'm looking into what version of gcc to use and how to setup that to be able to crosscompile the code.</p> <p>There seem to be some arm projects out there but I don't know what to start with, can somebody push me in the right direction?</p> <p>Thanks Johan</p> <hr> <p><strong>Update</strong>: There seems almost to be what I want from <a href="http://www.codesourcery.com/sgpp/lite/arm/portal/release830" rel="noreferrer">codesourcery</a>, but they seem to focus on IA32 and not AMD64.</p> <p>However in the supported devices I find the Cortex-M3</p> <ul> <li>ARM EABI, ARM M-profile Simulator -mcpu=cortex-m3 -mthumb</li> </ul> <p><strong>Update</strong>: There is a possibility to install IA32 on AMD64, so maybe the marked answer is obsolete already.</p> <p><strong>Update</strong>: Found this link about crosscompile for the Cortex-M3.</p> <ul> <li><a href="http://www.eluaproject.net/en_tc_cortex.html" rel="noreferrer">http://www.eluaproject.net/en_tc_cortex.html</a></li> <li><a href="http://fanplastic.org/gcc-for-arm-eabi/" rel="noreferrer">http://fanplastic.org/gcc-for-arm-eabi/</a></li> </ul>

    2. COBuildroot is good for bigger arm:s, like ARM9,ARM11, Cortex-A8 (and if you want to run Linux on it). But not for the MCU style Cortex-M3 (that is more like ARM7). But thanks anyway.

    3. COThe link you have there is no longer correct after we restructured the eLua site, you can find the same page here: http://www.eluaproject.net/en_tc_cortex.html FYI, I have some separate instructions that work for building CodeSourcery's toolchain for 64-bit on OS X. It may not be too hard to adapt them to work on Linux as well: http://fanplastic.org/gcc-for-arm-eabi/

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
