197 <h2>Accessories</h2>\r
198 <ul>\r
199 <li>\r
200 <b>What power peripherals are required/desirable?</b>\r
201 <ul>\r
202 <li>There are several ways to power a Beagle. The option exists to feed the on-board regulators through either the 5V barrel connector input or USB input. When powered up over USB, the regulators are somewhat limited in what they can supply the system. Power over USB is sufficient as long as the software and system running perform some management to keep it under the USB current limit threshold. For simplicity and maximum capability, powering over the 5V barrel connector is typically recommended.</li>\r
203 </ul>\r
204 <ul>\r
205 <li>The power adapter is required to provide 5V over a 5.5mm outer diameter and 2.1mm inner diameter barrel connector (a barrel connector length of 9.5mm is more than sufficient). The recommended supply current is at least 1.2A (or 6W), but at least 2A (or 10W) is recommended if you are going to connect up anything over the USB. The actual power consumption will vary greatly with changes on the USB load. </li>\r
206 </ul>\r
207 </li>\r
208 <li>\r
209 <b>What are recommended LCD to add-ons?</b>\r
210 <br/>\r
211 <ul>\r
212 <li>\r
213 One option is the <a href="http://boardzoo.com/product_info.php?products_id=1" Class="external">BeagleBoardToys ULCD7 Lite</a>, which has support in <a href="http://beagleboard.org/project/angstrom">Angstrom</a>.\r

216 </li>\r
217 <li>\r
218 <b>How can a keyboard and mouse be connected? </b>\r
219 <br/>\r
220 <ul>\r
221 <li>\r
222 Use a mini-A to standard-A USB adapter when attempting to do so via the OTG port. Mini-B adapters will not work without additional hardware modifications. Recommended peripherals can be found on product pages.\r
223 </li>\r
224 </ul>\r
225 <ul>\r
226 <li>It is also necessary to build support for USB OTG host mode into your kernel.</li>\r
227 </ul>\r
228 </li>\r
229 <ul><li>The port can only supply 100mA, so a powered hub may be necessary for power-hungry keyboards and mice.</li>\r
230 </ul>\r
231 </li>\r
232 <li>\r
233 <b>What are some sources for further peripheral exploration?</b></li>\r

237 </ul>\r
238 </li>\r
239 <li><b>What is required to run software on BeagleBoard-xM Rev C?</b></li>\r
240 <ul>\r
241 <li>The revision ID on the board and the control signal for powering the USB hub on the board changed between BeagleBoard-xM Rev B and BeagleBoard-xM Rev C. Older versions of x-loader/MLO, u-boot and the Linux kernel did not properly utilize the revision ID settings on the board, so BeagleBoard-xM Rev B didn't include settings different than BeagleBoard-xM Rev A due to this issue. On BeagleBoard-xM rev C, with the USB hub changes on the board, it became necessary to change the board revision ID, resulting in incompatibility with older software. See the <a href="https://groups.google.com/forum/#!topic/beagleboard/2xhpUT2jzLE/discussion" Class="external">forum posts on this topic</a> for further details.</li>\r
242 <li>If the <a href="http://gitorious.org/x-loader" Class="external">latest mainline x-loader</a> and <a href="http://git.denx.de/?p=u-boot.git" Class="external">u-boot</a> are utilized, including the variations shipped on the microSD card on the board (available at circuitco.com/support), the revision will be properly detected.</li>\r
243 <li>The mainline kernel does not yet include the patch required to utilize the proper polarity for the USB hub power enable. Explore this <a href="http://gitorious.org/beagleboard-validation/linux/commit/bfca58987039791522d1821e0506f8a113a0c239" Class="external">candidate patch</a> for information on what to fix and potentially apply it. If an image of Angstrom is assembled using Narcissus, the result will be a working kernel using the sources in OpenEmbedded.</li>\r

256 <h2>USB-Related</h2>\r
257 <ul>\r
258 <li><b>Can the BeagleBoard or BeagleBoard-xM be powered over USB?</b></li>\r
259 <ul><li>Unfortunately, no. First, the validation image shipped with the board\r
260 is based on a 2.6.32 kernel with a bug in the USB interrupt management. This \r
261 bug has been fixed on newer kernels, but those kernels have not yet been added\r
262 to the BeagleBoard's validation image. A patched version of the 2.6.39 kernel\r
263 is currently being implemented to support BeagleBoard validation and is expected\r
264 to provide the solution.</li>\r
265 </ul> \r
266 <ul><li>Second, the default boot condition of the kernel is to power up \r
267 peripheral interfaces like the EHCI-based USB host on the BeagleBoard-xM \r
268 and DVI-D on both pre-xM and xM boards. The USB specification requires devices\r
269 to power up under 100mA (~500mW) and the USB hub circuit on the BeagleBoard-xM\r
270 may consume around 100mA itself. Modification is required to the kernel to\r
271 avoid powering up this section of the board until sufficient current is\r
272 confirmed by the software. In practice, most host machines will provide\r
273 sufficient power, despite this violation of the specification. Consider power\r
274 requirements before attempting to utilize USB to power the BeagleBoard or\r
275 BeagleBoard-xM.\r
276 </ul>\r
277 <li><b>Can the Beagle OTG port work in host mode?</b></li>\r
278 <ul><li>The jumper on the back of the board can be used to attach some\r
279 solder to, or a cable that has the pins shorted. Read more about this in the\r
280 <a href=http://beagleboard.org/hardware/design>System Reference Manual</a>.</li>\r
281 </ul>\r

284 <a name="Serial"></a><span style="float:right"><a href="#top">Back to the top</a></span>\r
285 <h2>Serial Port-Related</h2>\r
286 <ul>\r
287 <li><b>Why is there no output? Why is it not possible to type into the serial port?</b></li>\r
288 <ul>\r
289 <li>For original BeagleBoard, purchase the <a\r
290 href="http://www.digikey.com/product-detail/en/BBC01/BBC01-ND/1972181" \r
291 Class="external">recommended serial adapter</a>. The \r
292 BeagleBoard-xM utilizes a straight-through DB9 male-to-female serial cable.\r
293 <br />\r
294 Ensure that you are connecting:\r
295 <br/>\r
296 RX to pin 2\r
297 <br/>\r
298 TX to pin 3, and\r
299 <br/>\r
300 GND to pin 5.\r
301 <br />\r
302 Follow the steps outlined by the\r
303 <a href="http://elinux.org/BeagleBoardFAQ#Serial_connection_.231" Class="external">community FAQ</a>\r
304 and the\r
305 <a href="http://www.beagleboard.org/uploads/BBSRM_6.pdf">system reference manual.</a>\r
306 </li>\r
307 <li>For original BeagleBone, a USB-to-serial adapter is built-in. Install\r
308 the drivers for your operating system using the instructions on the <a\r
309 href="/Getting+Started">Getting Started page</a>.\r
310 </li>\r
311 <li>For BeagleBone Black, you need to buy a 3.3V serial adapter. See the\r
312 <a \r
313 href="http://circuitco.com/support/index.php?title=BeagleBone_Black_Accessories#Serial_Debug_Cables"\r

319 <li>\r
320 <b>Why are no boot messages visible on a custom kernel?</b>\r
321 <ul>\r
322 <li>Passing the wrong bootargs to the kernel is a possible cause. Linux kernels >= 2.6.36 are using ttyOn instead ttySn for the serials on OMAP, so set console=ttyO2,115200n8 in U-boot.</li>\r

401 <b>What do I need to do to get my software running on a BeagleBoard-xM rev C?</b>\r

403 <li>\r
404 The revision ID on the board and the control signal for powering the USB hub on the board changed between xM rev B and xM rev C. Older versions of x-loader/MLO, u-boot and the Linux kernel did not properly utilize the revision ID settings on the board, so xM rev B boards didn't actually include settings different than xM rev A to work-around the issue. On xM rev C, with the USB hub changes on the board, it became necessary to no longer use this work-around and to actually change the board revision ID. This causes older software to break. There is a bit more discussion on this on\r
405 <a href="https://groups.google.com/d/topic/beagleboard/2xhpUT2jzLE/discussion">the mailing list.</a>\r
406 </li>\r

408 If you utilize the latest mainline x-loader (\r
409 <a href="http://gitorious.org/x-loader">gitorious.org/x-loader</a>\r
410 ) and u-boot (\r
411 <a href="http://git.denx.de/?p=u-boot.git">git.denx.de/?p=u-boot.git</a>\r
412 ), including the variations shipped on the microSD card on the board (available at\r
413 <a href="http://circuitco.com/support">circuitco.com/support</a>\r
414 ), the revision will be properly detected.\r
415 </li>\r
416 <li>\r
417 The mainline kernel does not yet include the patch required to utilize the proper polarity for the USB hub power enable. You can take a look at this\r
418 <a href="http://gitorious.org/beagleboard-validation/linux/commit/bfca58987039791522d1821e0506f8a113a0c239">candidate patch</a>\r
419 for an idea of what to fix and potentially apply this patch to your kernel. If you assemble an image of Angstrom using Narcissus, you'll get a working kernel using the sources in Open Embedded.\r
