Hi all,
in the table in drivers/mtd/spi/spi_flash_ids.c there is a flag WR_QPP set against Macronix devices (including the ones Dumitru is just adding).
This is used when programming the devices on a 4-bit bus to select the command to use for programming - either CMD_QUAD_PAGE_PROGRAM (0x32) or CMD_PAGE_PROGRAM (0x2).
The Macronix devices that I have a spec for do not mention command 0x32. Each of the devices that I have a spec for ( MX25L25635F MX25U51245G MX25V8035F and MX25V1635F ) use command 0x38 instead.
We need to fix this, till now no Macronix has been tested with QUAD I think, please send the suitable fix will review.
Too bad that I don't have any Macronix part with me too.
Thanks Chin Liang
thanks!
