&lt;p&gt;&amp;nbsp; 您们好，看了AM335x SDK的DCAN向导文件，利用内核自带的驱动可以实现CAN通讯的测试，现在有几个问题需要请教下：&lt;/p&gt;
&lt;p&gt;&amp;nbsp; 向导链接地址：&lt;a href="https://software-dl.ti.com/processor-sdk-linux/esd/docs/06_03_00_106/linux/Foundational_Components/Kernel/Kernel_Drivers/DCAN.html"&gt;software-dl.ti.com/.../DCAN.html&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp; &amp;nbsp;1. 向导中最后说明驱动文件路径为：&lt;/p&gt;
&lt;table border="1" class="docutils" style="width:581px;height:44px;"&gt;
&lt;tbody valign="top"&gt;
&lt;tr class="row-even"&gt;
&lt;td&gt;1&lt;/td&gt;
&lt;td&gt;drivers/net/can/c_can/c_can.c&lt;/td&gt;
&lt;td&gt;DCAN driver core file&lt;/td&gt;
&lt;/tr&gt;
&lt;tr class="row-odd"&gt;
&lt;td&gt;2&lt;/td&gt;
&lt;td&gt;drivers/net/can/c_can/c_can_platform.c&lt;/td&gt;
&lt;td&gt;Platform/SoC DCAN bus driver&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;&amp;nbsp; 这两个驱动文件一个是core文件，一个是bus文件，那安装总线和设备分层思路，设备文件在哪里呢？&lt;/p&gt;
&lt;p&gt;&amp;nbsp; &amp;nbsp;2. 测试中通过cansend, candump, ip等命令来完成测试，实际程序开发中也使用这些命令吗？想知道实际应用中采用什么方式对can数据进行收发？&lt;/p&gt;
&lt;p&gt;&amp;nbsp; &amp;nbsp;3. SDK中是否有标准的can设备驱动程序？这样的话可以参考驱动程序自行开发驱动；&lt;/p&gt;
&lt;p&gt;谢谢！&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>AM3352 ADC讀值問題</title><link>https://e2echina.ti.com/thread/200816?ContentTypeID=0</link><pubDate>Thu, 18 Mar 2021 02:22:12 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:a8afedb5-b2ab-47cc-a5c3-9904791f3a55</guid><dc:creator>Daniel Cheng1</dc:creator><slash:comments>1</slash:comments><comments>https://e2echina.ti.com/thread/200816?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/archived-forums/f/stellaris-arm-cortex--m3-mcu/200816/am3352-adc/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Other Parts Discussed in Thread: &lt;/b&gt;&lt;a href="https://www.ti.com.cn/product/cn/AM3352" class="internal-link folder product" title="Link to Product Folder" target="_blank"&gt;AM3352&lt;/a&gt;&lt;/p&gt;&lt;p&gt;Hi&lt;/p&gt;

&lt;p style="margin-left:30px;"&gt;The pinmuxConfig function is a port initialize function and I think it only opearte the CTRL_MMR and MCU_CTRL_MMR registers,right?&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;But I think when we use the GPIO0_127 pin,we also need config the GPIO_DIR67 and GPIO_SET_DATA67 registers to set the output direction and initial level.&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;So is there have a function to config the GPIO direction and initial level?&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;Thinks,&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;Regards,&lt;/p&gt;

&lt;p&gt;将libpcap函数库下载到了Ubuntu中，有一个简单的测试程序，大概内容是查询可用的网口名，以为最后要在ARM3359开发板上运行，所以要用对应的编译器进行编译，但是编译过程中显示libpcap.so：不可识别的文件格式，无法实现正常编译，想请问了解到大神们，是什么原因导致这种情况发生呢？而且通过Ubuntu中的编译器可以正常编译，并且能够运行，但用开发板的编译器就不行&lt;/p&gt;
&lt;p&gt;我猜测：1、开发板编译器与libpcap数据库版本不符&lt;/p&gt;
&lt;p&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; 2、链接动态库的时候路径不正确&lt;/p&gt;
&lt;p&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; 3、开发板编译器本身存在问题&lt;/p&gt;
&lt;p&gt;求指教，感激不尽&lt;/p&gt;
