I'm trying to get a spi mt25ql128 flash memory working under mcp2210 in linux.
But it does not work. I load up the driver, force it off spidevs, set config 47 (everything sans key parameters).
Board probe the device, I can see some spi data and chip select but the probe hangs.
Am I missing something?
No IRQ or CREEK, only GPIO and SPI support.
