抱歉啊，這么久了，沒怎么看帖子。

進(jìn)入u-boot后首先要找到系統(tǒng)emmc，設(shè)置為當(dāng)前設(shè)備，默認(rèn)是外置sdcard。

在命令提示符下輸入“mmc"命令，看提示操作，記不太清了。
要啟動twrp，看看uboot的環(huán)境變量是怎么設(shè)置的，可以輸入"print"查看環(huán)境變量，找到相關(guān)的啟動命令，把里面的文件名改掉就行。
比方說把形如recovery.img之類的改成twrp.img ，xxx.dtb改成meson1.dtb，再把改好的命令輸入，加上一個啟動命令，大概是"bootm 0xxxxxxx - 0xxxxxxxx"，這兩個地址具體是多少不用管，它是用符號表示的。環(huán)境變量里都有的。

具體命令我真記不太清了，反正查看uboot環(huán)境變量、輸入help都有的，沒有刻意去記。

在uboot里應(yīng)該是能找到兩個mmc device的，一個外部sdcard，一個內(nèi)部emmc。輸入help，找與mmc有關(guān)的命令。
要從外部sdcard里啟動twrp，輸入下面的命令（“0”根據(jù)情況來改，也可能是“1”，表示設(shè)備號，文件要放置在外部sdcard根目錄且sdcard格式化為fat32。U盤也是可以的，但要把下面的“mmc”換成“usb”）：

fatload mmc 0 ${loadaddr} twrp.img
fatload mmc 0 ${dtb_mem_addr} meson1.img

然后把當(dāng)前設(shè)備設(shè)置成emmc，否則啟動twrp后不能掛載system分區(qū)，接著輸入下面的命令：

bootm ${loadaddr}
應(yīng)該就能啟動了，可以進(jìn)入shell，HDMI會有輸出的，要用鼠標(biāo)操作。

感謝摟主的指點。其實我也是這樣理解和實驗的，但問題是我這樣fatload mmc 0 1080000 twrp.img和這樣fatload mmc 0 ${loadaddr} twrp.img輸入命令都在敲回車后反饋為“（）”，感覺就是未能把twrp.img從mmc 0 （sdcard）加載到內(nèi)存，所以接下去的過程也就是做無用功。當(dāng)然我準(zhǔn)備再次試試........。另外我目前只提取到meson1.dtb，這兩個文件meson1.img和meson1.dtb不知能否轉(zhuǎn)換或通用。如果摟主有這些：meson1.img、twrp.img.......也就是你所說的那些必須的東西，能否發(fā)我郵箱zwqa202@139.com,在此先謝謝了！
