mega 2560 core not resetting from FTDI programmer?

Other Hardware 3rd Party Boards

Hello everyone, hopefully this is the right place for this question...

a while ago i bought this Mega2560-CORE board and recently i also got this FTDI programmer

and i can't get my head around it, i can't upload anything on it... used the mega2560 board with the correct port, windows 7 drivers for the ftdi are installed, and the core is healthy and cool. How do i know?

i used an UNO as an isp programmer and the ISP headers on the core, successfully burned the bootloader, also uploaded the blink example, and then a serial port writing bit of code. connecting the FTDI adapter, i can read everything the core is sending from the serial monitor.... so both are working

but when i upload code directly from the adapter, nothing happens... and eventually i get a timeout. has anyone had any similar experience before?is some pin broken on the core/ftdi converter?

thank you for your time...

When you used the Uno as an ISP to upload your blink example and serial port code it overwrote the bootloader. You'll need to reconnect it and burn the bootloader.
Whenever you use an ISP to upload code it removes the bootloader.

ohhhhh i cannot thank you enough! i've been working with standalone atmega328s and have always been using spi to program them. i had yet no idea that this was happening! burned the bootloader again to the core and now it's happily getting programmed via FTDI :smiley:

i owe you a beer sir!
