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!
