pmon的升级总是有些不方便,至少是要借助串口和串口工具
如果现场不方便连接串口,是不是可以使用网线升级pmon呢?
答案当然是可行的。
环境:2k1000+linux3.10+麒麟的文件系统
如今我已经把这个工具开发出来了。
GitHub - zhaozhi0810/pmon-ls2k1000-2022 tools/program-2k1000-pmon 目录下包含源码,还有编译出来的工具。
烧录的过程大概需要1分钟左右。可以稍微等待一下!!
我这做了一些选项 (修改dtb的部分没有实现,暂时好像没有这个需求)
选项
-o gzrom-dtb-new.bin 读出flash中的程序(1m以内)
-e env.bin 写入env数据:要求有校验和+正确的格式
-d dtb.bin 写入dtb
-c gzrom-dtb.bin 比较flash中的与文件是否相同(只比较0-0xfb000这一段)-w gzrom-dtb.bin 直接写入gzrom-dtb.bin
gzrom-dtb.bin 与-w的功能相同
我升级了很多次,确定没有问题才分享出来。(但是仍然有风险,风险自担)
下面是源码:(两个c文件一起编译就可以了)
