Finally I can flash the bootloader with a NANO, its working well.

Seems too quiet ...
Is anyone actively using this solution?
I would love some tips on setting up an eq-3 :), manly which belts/pulleys to buy, etc

Yes of course after soldering, I guess the mega was bad so I ordered a new one

Have you checked the board for shorts/cold solder joints/incorrect components, etc?

I made the pcb 4.5 and tried to flash via ISP port, but no luck I guess the mega its bad

I've used ArduinoISP to program the ATMega162 with it's bootloader quite successfully in the past.

Try the following instructions:

Program your Arduino with the ArduinoISP sketch.
Open command prompt (or a terminal if linux).
Change to the bin/ directory in the AstroEQ config utility
Run the following command (changing the path to point to wherever you saved the bootloader file, and the port to match your Arduino)

Code: [Select]
avrdude -C../etc/avrdude.conf -v -v -v -patmega162 -cstk500v1 -P\\.\COM10 -b19200 -Uefuse:w:0xFB:m -Uhfuse:w:0xDC:m -Ulfuse:w:0xFF:m -Uflash:w:optiboot_atmega162.hex:i -Ulock:w:0x0F:m
Assuming you have your pin connections correct, this should work. I'd plug the chip into the AstroEQ board, making sure you apply the 12V DC power supply, that way the 16MHz crystal is connected up to the chip which will be needed for programming. You can then connect the MISO/MOSI/SCK/RESET/GND pins from the AstroEQ boards ISP header to your Arduino (don't connect the 5V line as that is powered by the AstroEQ regulator).

Only the PIC, but yesterday I spent about 5 hours to flash with Ardunio IDE (ard as ISP) the bootloader to mega162 via mega2560 without any luck and also I cannot flash mega2560 -> mega2560 (bootloader) I every time I got invalid signature (PINS was ok), I read the total internet about this

Did I supply the ATMega as well as the PIC? (can't remember now). If so, it should already have the bootloader on it.

After some research I need to burn bootloader to atmega162... update will come

I bought about 1 year ago the board from, with pre programmed pic18f14k50, now I have time to made the a board, but I cant flash it.
Astroeq driver successfully installed, but I got this error.
Power LED is on, USB LED just flashing.

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00

I need to flash optiboot_atmega162.hex to ATMEGA162?

thank you in advance
