Hello!
I can`t write fuses of Atmel ATMEGA328P.
I`m connect RT809F programmer how wrote in theme http://www.ifix.net.cn/thread-12996-1-8.html
Flash and EEPROM areas write and read OK.
But when I press button "Configuration bit" in left area or select "Operation" -> "Protect chip" in main menu, then window "ATMEL MCU Config Bits" appears with blank checkpoints. If I set bits in this window and press middle button (OK), then message "Operation successfulЈ¬Elapsed timeЈє6.35 secondsЎЈ" appears in main window RT809F software. But if reading chip, then from address 8400 exist old configuration bits.
"00008400: 26 B7 FF A2 FF FF FF FF FF FF FF FF FF FF FF FF"
And more: If I reading chip, then in "Configuration bit" window don`t see read fuses, I see blank checkpoints. After read chip I can see Configaration bits only in buffer from 8400 address.
I erasing chip, Blank check - OK, but I see this line in buffer:
"00008400: 26 B7 FF A2 FF FF FF FF FF FF FF FF FF FF FF FF"
RT809F can read and write fuses bits of Atmel ATMEGA328P ?
If yes, then how I can write fuses bits to Atmel ATMEGA328P ?
Software RT809F 20190701.
I need set fuses bits is: Low - F7, High - D9, Ext - FD.
