[红米AX6] AX6 TTL救砖求助

起因:扩容
先在mtd12刷了一个临时的op,然后进入临时op,把原有的mtd13、14合并扩容,并刷入了另一个OP
后正常进入另一个OP,进入后,将mtd12刷入了官方的固件,后发现mtd13的分区不能直接在web界面刷入另一个版本的op,于是打算扩容后进入官方的固件,去刷写现在扩容后的mtd13分区


悲剧应该就是这样产生的,在mtd13分区内的op,设置好从mtd12的官方固件启动,reboot之后,就砖了。


现在回头分析原因,应该是因为扩容后的分区表,官方固件不识别,或者找不到官方固件的mtd14,overlay分区了,因此无法启动进入系统。



按照坛子里的帖子,TTL接好线,设置好putty,通电跑马。现在的问题是,进入跑马后,按回车不能中断启动,机器依然启动死循环。

TTL芯片PL2303HX,目前怀疑,是否USBtoTTL芯片兼容性差,造成回车按钮不能正常识别。请各位大佬百忙中抽空指点。

印象中这种不是ttl兼容问题  我记得这种情况是无法中断的  只能拆机编程器  还有一种是启动前面带个  B开头的也是无法中断
