Actel FlashPro Devices</h2></div></div></div><p> |
| On Windows hosts, Sourcery G++ Lite supports FlashPro devices used with |
| Actel Cortex-M1 development kits. |
| </p><p> |
| For FlashPro devices, the <em class="replaceable"><code>device-url</code></em> |
| has the following form: |
| |
| </p><pre class="screen">flashpro:[//<em class="replaceable"><code>usb12345</code></em>/][?jtagclock=<em class="replaceable"><code>rate</code></em>]</pre><p> |
| </p><p> |
| The optional <em class="replaceable"><code>usb12345</code></em> part indicates |
| the ID of the FlashPro device to connect to, which is useful if |
| you have more than one such device attached to your computer. |
| If the ID is omitted, the Debug Sprite connects automatically to |
| the first detected FlashPro device. |
| You can enumerate the connected FlashPro devices by invoking the |
| Sprite with the <code class="option">-i</code> switch, as follows: |
| |
| </p><pre class="screen">> arm-none-linux-gnueabi-sprite -i flashpro:</pre><p> |
| </p><p> |
| The <code class="literal">jtagclock</code> option allows the communication |
| speed with the target board to be altered. The |
| <em class="replaceable"><code>rate</code></em> is specified in Hz and may range between |
| 93750 and 4000000. |
| The default is 93750, the slowest speed supported by the FlashPro device. |
| Depending on your target board, you may be able to increase this rate, |
| but beware that communication errors may occur above a certain threshold. |
| If you encounter communication errors with a higher-than-default speed |
| selected, try reducing the speed. |

| Windows drivers for the FlashPro device are included with the |
| FlashPro software provided by Actel. Refer to |
| Actel's documentation for details on installing this |
| software. You must use the Actel FlashPro software to configure |
| the FPGA on your Cortex-M1 board, but it does not need to be |
| running when using the Debug Sprite. |
| </p><p> |
| Once you have set up your board using the FlashPro software, |
| you can check that it is recognized by the Sourcery G++ Debug Sprite |
| by running the following command: |
| |
| </p><pre class="screen">> arm-none-linux-gnueabi-sprite -i |
| flashpro: [jtagclock=<n:93750-4000000>] FlashPro device |
| flashpro://usb12345/ - FlashPro Device |
| ...</pre><p> |
| |
| If output similar to the above does not appear, your FlashPro |
| device is not working correctly. Contact CodeSourcery for |
| further guidance in that case. |
