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. Thanks, Andy. ^ permalink raw reply [flat|nested] 3+ messages in thread

There is an 'sf status' command in the Chromium tree. Regards, Simon ^ permalink raw reply [flat|nested] 3+ messages in thread

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! -- Jagan. ^ permalink raw reply [flat|nested] 3+ messages in thread
