Hi guys, I am new to Arduino. Now I want to update my Arduino program by UART, the details as below: [8572392ecb1c4fc72b07481d1a749f4] Any relevant information and advice is appreciated. Thanks!

Hi everyone, A lot of thanks to everybody's help. At last, I address this issue and make a summary about it at here . Following are the answers to my questions above: Arduino IDE --> Tools --> Burn Bootloader is the bootloader(according the command, we can find the bootloader source code); Compa…

@GolamMostafa yes, I can read the hex file according to the doc; I just know that the hex file can include the address info than bin. Am I right?

@GoForSmoke Thanks for your help. Even if you don't use this, it should give insight into Duino's and be interesting as well. His second example uses the ATmega1284P! Could you give me a URL? I am not very clear about what is Duino. Thanks again!

Just for your information: [Intel-HEX-2]

[image] shadowthreed: we can find that the bootloader's address is 0x7800. So we just need to jump to that address to execute the bootloader. Flash Memory of ATmega328P is word-organized; where, every word-location (16-bit) has an address. The Boot Flash Section of the ATmega328P of the UNO …

@GolamMostafa @Budvar10 @GoForSmoke Another question is in my mind that I ever tried following the steps to burn my application: Arduino IDE --> Tools --> Burn Bootloader; (successful) Arduino IDE --> Sketch--> Upload Using Programmer; (successful) Arduino IDE --> Sketch--> Upload; (failed) Beca…

@GoForSmoke Thanks for your sharing!

[image] shadowthreed: Here, my question is "What is the difference between Upload and Upload Using Programmer? From the phenomenon above, I guess the operation of Upload Using Programmer will erase the bootloader, and also when burn bootloader, the application also would be erased. Am I right? …
