OpenSprinkler Forums OpenSprinkler Unified Firmware Question about blank Atmega644 programming… Reply To: Question about blank Atmega644 programming…



Hello again from me!!!

I’ve builded my own opensprinkler hardware based on 2.2 smt variant.Still don’t have usb serial chip CH340G on my board(ENC28J60 also still  missing) . I flashed  trough ISP directly into the blank atmega644p this file  firmware2.1.2.hex using usbtiny programmer and avrdude with this command:avrdude -c usbtiny -p m644p -U flash:w:firmware2.1.2.hex

But after this,nothing happened;( Is this a right procedure or I’m missing something?I didn’t find any info how to flash first the bootloader(optiboot),so i decided to go straight to the firmware…Any help,tutorial  will be very helpful.

Thanks in advance!
