EBF6ULL S1版本使用SD卡

oliveryang

我有一片野火i.MX6ULL開發板，用了野火提供的Debian映象檔，用SD卡開機之後就直接把OS寫入裡面的eMMC，所以SD卡接線訊號是沒有問題的。
現在我遇到一個問題是，eMMC開機後，我把SD卡插進去SD卡的插槽，在/dev/底下沒有任何新的硬體裝置冒出來，我有注意到SD卡在燒錄至eMMC的過程，eMMC的裝置名稱是mmcblk1，SD卡是mmcblk0，但是直接從eMMC開機後插入SD卡就是沒有反應，有想過是不是WiFi/BT沒有關掉，用fire-config確認過是關閉的，不曉得是不是有其他地方需要注意才能使用？我只是要把SD卡當成儲存裝置，或者把eMMC整個複製到SD卡上，不過這兩個前提是系統要先認得SD卡才行。

先謝謝各位先進的回答。

先断开wifi模组的电源试试

請問是J2嗎？上面沒有jumper。

硬件上SD卡和WIFI公用同一组SDIO？

君负花开

可以把内核打印的信息发出来看看，命令是dmesg

這是dmesg的輸出

這是dmesg的輸出

ls /dev下面有没有跟SD卡有关的设备呢，看这个信息，好像都没有发现SD卡

SD卡有自己的設定檔案嗎？在uEnv.txt裡面確實沒有看到。
SD卡插入的時候，/dev底下沒有多出任何裝置，我把SD卡用USB讀卡機插到USB的插槽，倒是有出現sda的裝置，可以正常讀取。

另外一件事情，開機的dip switch (SW5)不論是撥到SD開機還是eMMC開機，只要SD卡槽裡面有可以開機的SD卡，都會由SD卡開機。

SD卡没有什么配置项；
是的，因为uboot的设置是优先从SD卡启动的

我尝试了一下，是可以找到SD卡的

謝謝您的回覆，我看到你的訊息發現您在開機的時候SD卡就已經在上面了，而我之前的作法都是在已經開機的時候把SD卡插進去，所以我試著先放一張空的SD卡再開機，然後mmcblk0就出現了，我想這樣算是可以用了。我有用過的其他系統都是可以在開機的狀態插入SD卡，所以可能i.MX不支援熱插拔。謝謝所有前輩的協助。
