| Jun 6, 2023 at 6:46 | comment | added | DavidM31 | Good question about the boot-loader. The code is running as I can interact with the overall electronic as expected. Are bootloader ROM area and Flash ROM area two different memory areas? I.e. a .HEX file coud be uploaded overlapping both bootloader ROM area and Flash ROM are?! | |
| Jun 6, 2023 at 6:42 | comment | added | DavidM31 | Thank you @JRobert for your update: the binary code in the Arduino Nano is the only copy I have. I don't have the source code unfortunately (the guy who made it left a long time ago. Therefore there is no way to recover the source code). | |

| Jun 5, 2023 at 8:35 | comment | added | DavidM31 | About the memory operation (-U option), I used the setting from the following website: evilmadscientist.com/2011/…. Reading it again it is about downloading a raw binary format. | |
| Jun 5, 2023 at 8:32 | comment | added | DavidM31 | About the part number (-p option), I initially use 'm328p' (value given when I tried to use Arduino IDE). However, now looking at the schematic of the Arduino Nano from Gravity, I see the microcontroller 'ATmega168' is used. So I assume I should use 'm168' by the end... | |
| Jun 5, 2023 at 8:30 | comment | added | DavidM31 | About the programmer ID (-c option), here is something I don't understand well. I have a doubt about the one to choose, 'arduino', 'usbtiny', ... I keep 'arduino' as I have a bit of communication with it at least... | |
| Jun 5, 2023 at 8:23 | comment | added | DavidM31 | I consider the port ID is typed correctly as during the avrdude attempts I see the leds blinking (Rx, L). It means there are some data going through the Arduino USB Rx line at least... | |
| Jun 5, 2023 at 8:22 | comment | added | DavidM31 | I have only one Arduino Nano board. I can not try with another one. | |
| Jun 5, 2023 at 8:22 | comment | added | DavidM31 | I tried with 2 mini-B USB cables. The behavior is strictly the same. To notice that those cables are not original ones delivered with the Arduino board. | |
| Jun 5, 2023 at 8:18 | comment | added | DavidM31 | About 'blank' I wrote it incorrectly (excuse my English I am French ;-)). I meant 'blink' i.e. the led is blinking during the avrdude attempt. | |
