Hello!
The chip detects as both MT25QU256 and N25Q256..1E:
Found Micron/Numonyx/ST flash chip "N25Q256..1E" (32768 kB, SPI) on ft2232_spi.
Found Micron flash chip "MT25QU256" (32768 kB, SPI) on ft2232_spi.
Multiple flash chip definitions match the detected chip(s): "N25Q256..1E", "MT25QU256"
I tried both for reads and both worked. writes/erases were only tried on MT25QU256 and that’s what I am attaching the log file for (it contains both read and erase/write portions so no duplicate ones are needed I imagine?)
