Hi,

I'm trying to use avrdude to program the watch using OSX. I think I have installed the usb drivers correctly, because when I insert the programmer, I get a new tty.wchusbserial1410 in my /dev/ folder.
I am using this command to program the watch. When I start the command, the white light on the programmer flashes and the watch turns on, so I think it is connected in some way.

bash-3.2$ avrdude -v -v -v -v -b 76800 -p m328p -c arduino -P /dev/tty.wchusbserial1410 -U flash:w:watch_eng.hex -U eeprom:w:watch.eep

But it doesn't seem to be fully connecting for some reason. I've attached an image of my setup. Programmer is 3v3 and the wires seem to be correctly connected. Normally I hold the pogo programmer down on the watch.

I'm wondering if avrdudess does something extra other than calling avrdude. Also, do I need to use the fuse and lock bit commands?

Any suggestions are appreciated. Has anyone gotten the programmer to work on OSX?

Hey, the latest batch of watches uses 57600 baud instead of 76800.

Code:
-b 57600

Fuse and lock bits don't need to be changed (they can't be changed with the serial programmer anyway, you need an ISP attached to the SPI pads for that).

Thanks! I thought that I tried that baud rate before, but all of a sudden it seems to work.

Hi,

I've created a minimal makefile that works with CrossPack avr environment on osx.
http://www.obdev.at/products/crosspack/index.html
As you can see below, the files seem to compile and link into an elf and hex file when I type "make all".
When I try to install it using "make program", the watch shows nothing.
When I load the original watch_eng.hex using "make programorig", the watch is functional again.

I suspect there is something wrong with my mywatch.hex file, but any suggestions are appreciated.

Thanks.

Just noticed that my mywatch.hex file is not the same size as the watch_eng.hex. Can you let me know the size of the watch_eng.elf? At least we can isolate the problem to the hex creation.

My elf size is 227311 bytes.
There seems to be a lot of arguments missing in your makefile, here's the full list:

I'm also using AVR-GCC 4.7.2.

Thanks for your help with this. I've updated the makefile to match your flags. It seems to compile ok.

I was wondering if you could post the results of "ls -la *.o */*.o" for your watch folder after you compile it on your system. It would help if I could compare the file sizes and the files.

I think another area where I'm having trouble is the assembly files. draw_bitmap.S seems to compile (see below), but not milli_isr.S

Quote:avr-gcc -mcall-prologues -funsigned-char -funsigned-bitfields -DF_CPU=8000000UL -DCPU_DIV=clock_div_1 -Iincludes -mmcu=atmega328p -c millis/millis_isr.S
millis/millis_isr.S: Assembler messages:

millis/millis_isr.S:30: Warning: constant out of 8-bit range: -7999744
millis/millis_isr.S:30: Error: garbage at end of line

I think this is because the program that you are using preprocesses assembly differently. I've tried various things, but if you can think of something, let me know.

Here is the results of the new makefile. When I load it in the watch, still nothing shows up. I guess millis_isr is used for showing time.

Ah forgot about the asm parts, args for ASM AVR-GCC:

Code:
-Wa,-gdwarf2 -x assembler-with-cpp -c -mmcu=atmega328p -DF_CPU=8000000 -I "../includes"  -mrelax -Wa,-g

You need the "-x assembler-with-cpp" part.

millis_isr.S deals with the millisecond counter interrupt.

Args for making .hex form .elf:

Code:
-O ihex -R .eeprom -R .fuse -R .lock -R .signature -R .user_signatures

Args for making .eep from .elf:

Code:
-j .eeprom --set-section-flags=.eeprom=alloc,load --change-section-lma .eeprom=0 --no-change-warnings -O ihex

Be sure to upload the .eep with the .hex, it contains things like the beep tunes.

Thanks for all of your help with this. It compiles everything now and loads into the watch! Here is the working Makefile. I'm using CrossPack-AVR-20131216.dmg, which has gcc version 4.8.1 (osx 10.9.5). The object files are bigger than the ones that you posted, but everything works fine.

Hi Chang, I am not a programmer and none of this makes any sense to me. I am dumb as mud.

Can I ask what are you trying to program for the watch? A game? A additional feature/option? If so will you share it with other N|Watch owners?

I am going to make a thread asking programmers, if they make/program something for the N|Watch post it in thread.
