flashing in-system (ISP) is sometimes a very delicate procedure. How and if it will work, depends on many things: 1. is the board designed for ISP; if, follow the manual; if not 2. how do you power the flash chip? through the board's regular power supply (strongly advised)? or through the ch341a (discouraged unless you know exactly what you are doing)? 3. are all input pins of the flash chip in a defined state? (e.g. don't forget /HOLD and /WP). See also [1] and [2]. > The EEPRom I'm trying to write is > S25FL128SAGMFI000. Regarding ISP, the board the chip is soldered to matters more than the chip. What board is it?
