Rejecting non-ST MCU probably has also a deeper impact. The need to read the MCUID! This has often problems when in sleep or even when in reset. Even with stprog, STLINKV3 often does to to a board the STLINK-V2(1) had no probblem. > First, a word of warning: V3J6M2 firmware will enable permanent protection > level 2, so you won't be able to debug ST-Link itself over SWD on this chip > ever (reflashing via the bootloader would still be possible though).
