sunxi-fel 的相关命令

本文主要是介绍sunxi-fel 的相关命令，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

简介

这个命令是全志芯片的烧写程序。有很多写法。
例如 : F1C100S 、F1C200S
这个命令有很多隐藏的相关问题（这里不讨论）

常用命令说明

获取flash的相关信息

$ ./sunxi-fel.exe -p spiflash-info
Manufacturer: Winbond (EFh), model: 40h, size: 33554432 bytes.

意思是 连接了 32MB 的FLASH，至于是NAND还是NOR。
flash的类型可能对板子有很大的影响。

这是一个 f1c200s开发板（使用了128MB NAND flash）的返回。（应该坏了）
$ ./sunxi-fel.exe -p spiflash-info
Manufacturer: Unknown (00h), model: C8h, size: 131072 bytes.

列出所有的FEL设备

$ ./sunxi-fel.exe -l
USB device 001:006   Allwinner F1C100s

显示BROM信息

这是F1C100S里面的信息

$ ./sunxi-fel.exe ver
AWUSBFEX soc=00001663(F1C100s) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000

烧写程序到内存

这种方式，板子重启程序就没了。
将程序写到内存中并运行。
有好几中方法

./sunxi-fel.exe uboot ./uboot-with-spl-usb.bin 

这里运行uboot对应的bin之后，进入uboot模式，然后就可以执行对应的uboot命令了。

烧写程序到flash

这种方式，板子重启之后程序还在。

./sunxi-fel.exe -p spiflash-write 0x0 "u-boot-sunxi-with-spl.bin"
./sunxi-fel.exe -p spiflash-write 0x6000 "spl-separated.bin"
./sunxi-fel.exe -p spiflash-write 0x400000 "logo.bin"

解释：-p 是为了显示程序进度
0x0 是程序写入的地址
正常情况下写一个bin就好了，有的情况会写两个。写到0地址的负责引导，写到其他地址的是实际的程序。
