However, the Freedom board has no jumper or other means to power the USB bus (which is required in the USB host mode). So if I want to get access to a memory stick from the KL25Z, then I’m stuck because the board does not offer that option. Luckily there is an easy hack to work around this.</span></p><p style="margin:0;padding:0px;text-align:left;background-color:#ffffff;text-indent:0px;color:#333333;">&nbsp;</p><p style="margin:0;text-align:left;background-color:#ffffff;text-indent:0px;color:#333333;"><span style="font-family:tahoma, arial, helvetica, sans-serif;font-size:12pt;">more on The Knode - <a class="jive-link-wiki-small" href="/products/devtools/kinetiskl2freedomboard/w/documents/10817/tutorial-for-frdm-kl25z-usb-host-mode-hack-for-the-freescale-freedom-board">follow this link</a></span></p><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: freescaledocs, Freescale Tagged Content, freescale, frdm-kl25z, development-tools</div>
