注意JCG Q20的U-Boot版本

nas***

新版的原厂U-Boot使用了lzma-loader，比如 U-Boot 2018.09 (Nov 20 2020 - 19:56:59 +0800)
直接刷OpenWRT会导致引导时循环报错

这货现在翻车概率相当高了.哪怕是TTL刷bootloader也有概率死循环

bootloader不需要改，原厂就是最好的

大佬，这个代码怎么用啊

新版的能引导老子不？

能，hiboy版网页直刷什么都正常

hui***

电信送了个，直接升级挂了...........

原来如此，之前查过“uncompress error”，但是没找到相关的，然后对比了下提示信息里面的“Image Type”，还以为是文件自身有问题或者分区不对

怎么看原厂的是新版还是旧版U-Boot呢
