May 18, 2020 ESP8266 and ATmega8 UART. I connect ESP8266 with ATmega8 using UART. I send some value from ESP8266 to ATmega8 on that basis of the value ATmega8 send back some value to the ESP8266 and this is working fine but after few hours ATmega8 does to send data after resetting ATmega8 its working fine but then again a few hours later its stop send data.

greets,

I'm interested in how to program (via UART) a atmega8 and/or atmega328 that has the arduino boot-loader installed.

Let's say that my code jumps to the boot-loader section when it receives a specific uart command or the fuses are programmed so that on reset the boot-loader section runs first.

Is there a way to send a hex file over to the UART Rx (at slow baud rate) and for the arduino boot-loader to write the code to the application section of the flash memory?

As an example:1. PowerOn2. Bootloader loads/runs and waits (a second or two) for a specific UART byte that tells it to program the next bytes (the hex file) into the application section of memory.3. Hex file is sent via UART (at slow baud rate)4. Specific UART byte tells the boot-loader that it's the end of the hex file.5. Atmega resets

I've looked at the Atmega8 bootloader here https://github.com/arduino/Arduino/blob/master/hardware/arduino/avr/bootloaders/atmega8/ATmegaBOOT.cbut it's a bit too complicated for me.
