Hello,

Is there, or is anyone working on, code for controlling the write protect pin of SPI flash devices using a GPIO? In effect an "sf protect <on|off>" command? I have had a look in 2014.07 which is on the platform we are using but can't see anything.

Just try this - CONFIG_SYS_SPI_ST_ENABLE_WP_PIN

Heiko has recently added this for hardware protection W#/Vpp signal I don't know will this helps your requirement of not.

thanks!
