Hi there,
I recently bought 10 FT232RL from https://www.ut***.net at USD 3,5/pc, so I did not expect to get faulty chips. However the chips cannot change EEPROM content using FT Prog, Whatever I change, it seems the programmer programs, however no change are visible in the read od EEPROM. Probably the chips are fake and have no EEPROM, but ROM inside. The serial number are A50285BI, production series GC370111. I would appreciate if you could give me your opinion. Attached screenshots.
