Ah ok, I think this is an issue with the str7, rather than openocd. The flash protection is being removed (until next reset) but we are reading the non-volatile register (FLASH_NVWPAR). This is read at reset and any write to this register only effects the volatile version of FLASH_NVWPAR. The address of the volatile version is unknown. so it is working internally, just the info from protect_check only relates to the volatile FLASH_NVWPAR. Perhaps a str7 specific note needs adding.
