help me to install correct bootloader on custom arduino MEGA2560 BOARD and get code uploaded

Hello, Deep is here from India. I can help you to upload bootloader code to your custom ATmega2560 board.

HI, I am kahan. I am embedded developer and have much experienced in hardware and software side. Waiting for your positive response. Thank you.

Hello, I'm interested in your project. I have experience in the programming of 8 and 32 bit microcontrollers. I have previously worked with custom Arduino Uno and Mega cards. Could you show me the current circuit you are using? Feel free to contact me to further discuss this position.

Hi, I can help you with this. Can you please open the chat thread and then lets look into the custom board and re-flash the bootloader. Thanks Fernando

Hi, I am expert in Arduino. I will do this task for you! I will upload the correct Bootloader into your Arduino MEGA2560 board and then code successfully!

hi, I am here to help . no need reward I did have a little knowledge but with atmega328 ones just a hint to consider - make sure the fuse setting are right (dont set external xtal fuse on if the mega dont have xtal attached. or iw till brick, for safety you can test with internal oscillator / low mhz setting first ) - make sure if the mega is not locked (the signature can be detected by programmer) if those two requirement are met, pin used for burning/program are the same (mosi/miso/sck/rst/gnd/vcc) goodluck !
