Trying to add Atmega 328pb on Windows

[Arthrimus]

I have added an entry for the 328pb in the config.c file with the correct ID but when I run the command to program the chip I get the error "No such chip" and a listing of all of the available chips from the config file. My entry for the 328pb doesn't show up in this list.

I am using chavprog.exe on windows.

Hello, could you provide your workflow? I am wondering if program was recompiled after addition of your device to the config.c?

[Arthrimus]

I did not recompile the program after editing the config.c file. Could you please explain how to do that in windows? I didn't see anything about it in the documentation.

In general, it's not very easy task to do. You need to install Cygwin (for example) and normally compile program with "make". Unfortunately, I am not experienced in development under Windows, so I am not very helpful. I've heard that modern versions of Windows contains a Linux subsystem, so you probably may consider to use it. In that case compilation should be as easy as run "make" in the folder with modified source.

Ok I attempted to run make in Cygwin. I get the following error. I did add Libusb1.0 in the cygwin installer. Do you have any suggestions?

$ make gcc -std=gnu99 -Wall -O2 ch341a.c main.c chavrprog.c config.c ihex_copy.c ihex_parse.c ihex_record.c -o chavrprog -lusb-1.0 ch341a.c:21:10: fatal error: libusb-1.0/libusb.h: No such file or directory

include <libusb-1.0/libusb.h>

      ^~~~~~~~~~~~~~~~~~~~~

compilation terminated. make: *** [Makefile:7: chavrprog] Error 1

Please, post the output of the folowing command: cygcheck --check-setup | grep -i libusb

[Arthrimus]

$ cygcheck --check-setup | grep -i libusb libusb1.0 1.0.21-1 OK

[Trel725]

You need to install the development version of libusb, libusb1.0-devel.

That worked, thanks so much for your help!
