    Perhaps you've not (yet) realized that your attempt to "secure" your code by "disabling JTAG" (continuing this on-going bombardment of "security" posts) will fail as the same means to "dump" (really, load) code (via UART) enables interested "others" to "read back" every one of your (still) unprotected flash bytes.

    While the ostrich may not "see" the charging lion (by burying its head in the sand) - that tactic offers (limited) (i.e. NO) protection.   So too your (endless) attempts to "secure" a very basic, low-cost MCU.  (by this and all other vendors)

    Hello Surendra,

    Regards
