Em9280內核升級到3.9.7后JP1失效 Post By:2013-9-27 21:09:00 [只看該作者]
今天升級內核到3.9.7后發現JP1失效,不管JP1是否短接糸統一直處于Debug狀態。請問是何原因?

您好,我前面已經把JP1短接和斷開的啟動信息都貼出來了。我感覺JP1還是起作用的,若不斷接JP1,啟動時進不了U-Boot,短接后按“空格”可進入U-Boot。勞駕分析一下是何原因。

啟動信息里,顯示配置有錯。請問你EM9280的版本號是多少,原來的是Linux-2.6.35還是CE6.0的?我們明天把最新的內核放到網上,你下載后再試試。如果還是不成功,就只有麻煩把板子寄回,我們幫你做好。

我們查了一下記錄,你手上的估計還是v3版本的,只有v4板子才能支持3.9.7升級。請把這張板子寄回,我們給你更換,謝謝。
