本文介紹聯發科mt6167平台faq晶元資料解決方法
mtk modem韌體編譯和引數配置的嗎?按照網上的「 射頻引數___mtk_固化射頻引數方法介紹_eservice.doc」之類的文件配置後,新編譯生成的韌體:資料網路連線後沒有上下行資料【無法上網】。meta工具匯出資料有些與校準引數相同,有些引數在原始碼中找不到配置位置的匯出後都是0或無效的數值。
是從校準好的板子匯出的引數ini檔案,然後逐條配置了可以配置的引數。
新韌體燒錄後meta提取出的引數,有些和原校準過的ini中的不同【**中找不到配置的位置】,比如:
[afc control]
initial value=4500
slope=7.5018
[gsm900 sub band, rx loss]
rx loss middle=0.00000,0.00000,0.00000,0.00000,0.00000,0.00000,0.00000,0.00000,0.00000,0.00000,0.00000,-12.375000

以上問題,該怎麼解決呢?
可參考相應的mtk原廠faq資料,或者諮詢相應工程師解決。
這些都可以到一牛網論壇上看看,有相應的技術資料和開發方案。
聯發科MT76x8使用2 編譯Uboot
參考官方資料 首先是環境配置 官方是使用的ubuntu14進行編譯的 這裡有個小問題,我事先在ubuntu19上編譯了,uboot編譯沒啥問題,但是編譯openwrt的時候ubuntu19移植報錯 估計是openwrt版本比較低,很多東西軟體包可能不支援了 不管那麼多,直接按照官方的說明來做就是了 ...
