    Hi there

    I have a problem when i’m using your patched hex file to flash my Arduino (328).
    I always get:

    avrdude -p m328p -c usbtiny -P /dev/tty.usbserial-A7006SAQ -b9600 -D -Uflash:w:grbl.hex

    avrdude: AVR device initialized and ready to accept instructions

    avrdude done. Thank you.

    Same, when i’m using the compiled hex file from the master branch on the github page from DANK.
    No problem if i’m compiling the hex file on my machine, flashing works!

    What are your fixes with the patch? Can you put the source files with the patch on your github page?

    Thank you for your help.

    You said you got an Arduino UNO in a email. Does it toss up the SAME error code when you try it?
    Try this avr-dude line:

    avrdude -p m328p -c usbtiny -P /dev/tty.usbserial-A7006SAQ -b9600 -D -U flash:w:default/grbl.hex

    Thanks to Riley it works now. My ISP Programmer (usbtiny from adafruit) didn’t like the parameter “-b 9600”. So after removing it, every worked well when flashing my Arduino.

    AHA! Very cool… I got home from work today and tried it out on my Macbook. Of course I still used my avrispmkII vs. your TinyISP. However it worked with avrdude today:

    ril3ys-MacBook-Pro:~$ avrdude -c avrispmkII -P usb -p atmega328p -U flash:w:Downloads/grbl_0_6b_atmega328p_16mhz_9600_with_grblshield_patch.hex

    If you are on OSX the AVR Mac Pack is a beautiful thing! Its a complete compiled toolchain for AVR. I installed that updated my path and I was good to go. I say this just an FYI for others.

    Just one more data point, I had to set my baud rate for flashing at 57600 to get it to play nice.
