网件614刷错了一个cfe,开机灯全亮,变砖了.
芯片是:MX29lv320cbtc-70g
brjtag 的/fc:参数该选哪个芯片阿 ,请各位高手帮忙~~~~~

哪位高手能说说"MX29lv320cbtc-70g"芯片的"OE#引脚",是第几个引脚?~~~


自己找到了在第２８引脚,把图发上来方便后来人

是哦　实在郁闷哦~~
刷错了cfe,结果灯全亮咯....

上面的强刷参数可以试试

qw***

强制参数错了。cbtc是 BotB的。所以选 mx29lv320ab

fc参数选31或32试试

先擦除吧，FLASH没擦干净，brjtag.exe -erase:cfe /fc:xx
/fc:xx  选32试试,因为软件不支持你那个FLASH，所以只有挨个试试

lh***

谢了　上面各位热心兄弟,我挨个试试..　

flari***

不行的话自己重新编译brjtag，加入你需要的芯片，好像就加一行就Ok了

qw***

选30 32都可以。先执行 清全flash 。遇到停止可以强制插拔路由电源。 多清几次。直到清全flash无停顿。

水平有限,哪位兄弟帮我编译一个支持这个芯片的吧
