| <p>In this section we check that some of the required tools / drivers have been |
| correctly installed and configured.</p> |
| <p>Connect your laptop / PC to the discovery board using a Mini-USB USB cable. The |
| discovery board has two USB connectors; use the one labeled "USB ST-LINK" that |
| sits on the center of the edge of the board.</p> |
| <p>Also check that the ST-LINK header is populated. See the picture below; the |
| ST-LINK header is highlighted.</p> |
| <p align="center"> |
| <img title="Connected discovery board" src="../../assets/verify.jpeg"> |
| </p> |
| <p>Now run the following command:</p> |
| <pre><code class="language-console">openocd -f interface/stlink.cfg -f target/stm32f3x.cfg |
| </code></pre> |
| <blockquote> |
| <p><strong>NOTE</strong>: Old versions of openocd, including the 0.10.0 release from 2017, do |
| not contain the new (and preferable) <code>interface/stlink.cfg</code> file; instead you |
| may need to use <code>interface/stlink-v2.cfg</code> or <code>interface/stlink-v2-1.cfg</code>.</p> |
| </blockquote> |
| <p>You should get the following output and the program should block the console:</p> |
| <pre><code class="language-text">Open On-Chip Debugger 0.10.0 |
| Licensed under GNU GPL v2 |
| For bug reports, read |
| http://openocd.org/doc/doxygen/bugs.html |
| Info : auto-selecting first available session transport "hla_swd". To override use 'transport select <transport>'. |
| adapter speed: 1000 kHz |
| adapter_nsrst_delay: 100 |
| Info : The selected transport took over low-level target control. The results might differ compared to plain JTAG/SWD |
| none separate |
| Info : Unable to match requested speed 1000 kHz, using 950 kHz |
| Info : Unable to match requested speed 1000 kHz, using 950 kHz |
| Info : clock speed 950 kHz |
| Info : STLINK v2 JTAG v27 API v2 SWIM v15 VID 0x0483 PID 0x374B |
| Info : using stlink api v2 |
| Info : Target voltage: 2.919881 |
| Info : stm32f3x.cpu: hardware has 6 breakpoints, 4 watchpoints |
| </code></pre> |
| <p>The contents may not match exactly but you should get the last line about |
| breakpoints and watchpoints. If you got it then terminate the OpenOCD process |
| and move to the <a href="../../start/index.html">next section</a>.</p> |
| <p>If you didn't get the "breakpoints" line then try one of the following commands.</p> |
| <pre><code class="language-console">openocd -f interface/stlink-v2.cfg -f target/stm32f3x.cfg |
| </code></pre> |
| <pre><code class="language-console">openocd -f interface/stlink-v2-1.cfg -f target/stm32f3x.cfg |
| </code></pre> |
| <p>If one of those commands works it means you got an old hardware revision of the |
| discovery board. That won't be a problem but commit that fact to memory as |
| you'll need to configure things a bit differently later on. You can move to the |
| <a href="../../start/index.html">next section</a>.</p> |
| <p>If none of the commands work as a normal user then try to run them with root |
| permission (e.g. <code>sudo openocd ..</code>). If the commands do work with root |
| permission then check that the <a href="linux.html#udev-rules">udev rules</a> have been correctly set.</p> |
| <p>If you have reached this point and OpenOCD is not working please open <a href="https://github.com/rust-embedded/book/issues">an issue</a> |
| and we'll help you out!</p> |
