編譯問題解決: MT7620A Uboot
解決MT7620A "Uboot" 編譯問題
SDK Version: 4.3.0.0
編譯問題：ERROR: ... mkimage: invalid entry point -n
進入Uboot路徑：執行make最後要產生boot.img時產生錯誤.
./tools/mkimage -A mips -T standalone -C none \
-a 0x80200000 -e \
-n "SPI Flash Image" \
-r DDR2 -s 16 -t 64 -u 32 \
-y 0xFF -z 0xFF -w 0xFF -d uboot.bin uboot.img
./tools/mkimage: invalid entry point -n
make: *** [uboot.img] Error 1
解決方法：
此一錯誤是由於系統語言不是英文導致,請進入Uboot路徑;編輯Makefile;找到
mkimage ...-e $(shell readelf -h u-boot | grep "Entry" | awk '{print $$4}')
這一行,這就是出錯的地方.
看看出什麼錯誤;在command line下執行: #readelf -h u-boot
Uboot# readelf -h u-boot
ELF 檔頭：

Uboot# readelf -h u-boot| grep '進入點位址'
進入點位址： 0x80200000
awk '{print $$4}'
改成
awk '{print $$2}'
重新編譯;終於成功了:

-n "SPI Flash Image" \
