试图用TFTP去写UBOOT，

MT7981> nmbm list

有刷机菜单应该是驱动对了uboot。

如果只是ecc的问题，可以修改dts不用on-die ECC，用host或者software ecc应该就行了（损失一点cpu算力）， ...

H大的Uboot也是软件ECC。

拿到手是刷过的，没有原始备份，boot时太快了，一瞬间就到了提示 Web failsafe UI started   URL: http://192.168.1.1/。之前的一瞬能看见一屏的区块不能识别一类的信息。

大佬，给个编程器的备份固件吧，看来我是要焊线上全包恢复了

别乱刷！你这个是NMBM把ubi分区全部标记成坏块了。用下面命令：

1. mtd erase.dontskipbad spi-nand0 0x07820000 0x007e0000

复制代码

重启后再执行一遍。

重新引导，恢复flash的，BL2，和阿三的uboot。

后再刷固件。别乱刷了。

强制擦除ubi分区，恢复被拉黑的块。你不明白吗？

感谢楼主，已用楼主的方法重新救砖，我的也是跟楼主的一样ubi分区全被NMBM拉黑了，然后用mtd命令恢复后就成功了

所有我觉得这就是为什么openwrt官方不开NMBM的原因。
