trying to recover a ubiquiti access point where the SPI flash was broken.
If I install a working MX25L12835FMI from another working unit, to the broken one, this unit is also working.
So I dumped the working SPI Flash and wrote to a new Flash, but the unit is not able to boot completely.
Any hinds why the copy is not working?
There is nothing written in OTP area and I also set the Status Register according the original chip.
CRC check is okay...作者: admin 时间: 2020-12-17 12:17
回复 1#tertomium Maybe the software has special encryption protection,
For example, read the SFDP table (the SFDP may be different depending on the factory date and version), encrypt the data, and so on
