I want to write/read some data into SM470R1B1MHKPS onchip flash, after following the procedure of read/write the protection key,
when I download and run my code through JTAG Debug, it works ok, but after I disconnect the JTAG and turn power off and on, the system shows repeat reset. If I write the wrong protection key, will it damage the chip? Please advise what is the problem. Thanks
