水星MW310R V4刷OPENWRT求助

CASPARTUNG

MT7620N的机子，改了8M闪存（MX25L6445E）和64M内存（HY5DU121622CTP-D43）刷u-boot-mw305r-64m-115200.bin能进入UBOOT，然后再刷了多个http://downloads.openwrt.org.cn/PandoraBox/MW305R/里的固件，都重启失败，TTL显示的都是Kernel panic - not syncing: Attempted to kill init!另外也尝试了RT-N14U_3.0.0.4_378_0-g精简编程器固件和如意云等固件，都启动不了，能启动成功的只有firmware-sdk，请问是什么问题导致内核错误？
这是其中一个固件的信息

换了内存就好了，新的颗粒都有问题{:soso_e131:}

lujz888

就v4版本的可以刷吗？
