也用过论坛里4500救砖的CFE,还是一样,我这是真砖了吗?
求高手给点意见

测量复位脚只有1.2V,后来发现是电容漏电,换掉电容后,复位脚电压3.3
不过上电,看信息还是一样。后来把CFE修改复位脚定义,可以过去了,但是反复重启信息如下:

感觉是芯片复位脚周边的硬件部分损坏了,打算淘宝重新买个芯片回来换上去。

你的重置键卡住了还是坏了?

没坏,是复位电路上的电容漏电,把复位脚拉低到1.2V,换了电容后,电压3.3V。但是故障依旧

我的也出现和你一样的问题了,请问是哪一个电容漏电呢,是开关旁边的绿色贴片电容么,还是哪一个?
我量了一下,电路板上能找到的4个电容,基本上都是正常的

还有我发现TTL接口确实只有两个信号线,你是焊接了2个信号线还是?我焊接了2,5,6脚,可以看到输出,但是无法中断CFE,估计是复位电路还没有恢复的缘故哈
