MX25UM25645G program problem
Posted: Mon May 12, 2025 11:18 pm
Trying to write to a MX25UM25645G octaflash chip. Chip ID reads correct and I can blank verify a new device and read/verify a device that has some unknown contents.
When I try to erase/write the chip I get a "device not found" "communication error".
I'm using a universal BGA24 to DIP8 adapter, but seeing that the ID is correct and reading seems to work there must be some other problem.
All my other programmers have similar behavior, reading works, writing fails or corrupts the chip. Something seems strange with these octaflash chips compared to single/quad SPI.
Any advice is appreciated, thanks.
