Hi everyone, I've looked through the forum for similar issues and haven't been able to find a solution. I'm having difficulty using a CP2102 to program an atmega328p chip on a breadboard with an external 16MHz oscillator. Pinout between CP2102 and atmega328p chip: DTR ->pin 1 (reset) TX -> pin 2 (RX) RX -> pin 3 (TX) Things that I have tried thus far: - Used an Arduino as ISP in order to burn bootloader onto chip * verified this was successful due to 3 blinks from LED on pin 19 after burning - Installed CP2102 drivers from Silicon Labs website for Windows 10 x64 () * verified this was successful through device manager - Tried to load blinky program via CP2102 to atmega328p * failed due to some sync issues. Not quite sure why, but I think this is the main issue - Loaded a Serial echo program to test if there are issues between TX and RX pins via ArduinoISP * successful install on atmega328p based on LED no longer providing 3 blinks (bootloader successfully overwritten) - Reattached CP2102 and viewed Serial monitor to send/receive data to atmega328p * successful data transfers, so I know RX and TX pin connections are correct and no issues involved between communication between CP2102 and atmega328p chip My best guess is that there is an issue between the Arduino IDE and the CP2102.

I know I will also have to reinstall the bootloader since it was overwritten with the Serial test. Maybe I'm using the incorrect programmer setting within the IDE, which I'm currently using 'AVRISP mkII'. Should I be using a different programmer from the list provided, or somehow install a 'custom' programmer so the IDE knows its using the CP2102? Thanks for any advice provided.

On this page. () • • • • • • • • • • The Bootloader The behaviour described above happens thanks to a special piece of code that is executed at every reset of the microcontroller and that looks for a sketch to be uploaded from the serial/USB port using a specific protocol and speed. If no connection is detected, the execution is passed to the code of your sketch. This little (usually 512 bytes) piece of code is called the “Bootloader” and it is in an area of the memory of the microcontroller – at the end of the address space - that can’t be reprogrammed as a regular sketch and had been designed for such purpose.

The Memory Map of an ATmega328P To program the bootloader and provide to the microcontroller the compatibility with the Arduino Software (IDE) you need to use an In-circuit Serial Programmer (ISP) that is the device that connects to a specific set of pins of the microcontroller to perform the programming of the whole flash memory of the microcontroller, bootloader included. The ISP programming procedure also includes the writing of fuses: a special set of bits that define how the microcontroller works under specific circumstances.

Use Arduino as ISP The whole process of loading the bootloader code and burning properly the fuses to make an ATmega microcontroller an “Arduino” is managed by the Arduino Software (IDE): it provides a specific menu item and allows you to use a variety of programming devices. Among the programmers, the “Arduino as ISP” is the cheapest and most practical solution to burn a bootloader on another Arduino board with ATmega, 32U4 or ATtiny. The programming process uses VCC, GND and four data pins. Three pins connect MISO, MOSI and SCK between the programming micro and the target micro, the fourth pin from the programming micro goes to the reset pin of the target.
