After I edit a fs file with python, just removing the ; to enable the NRF24L01, when I save the file it changes the size to 159kb no way that fs file will load.

This tool is a command line tool and isn't made for use with a graphical file manager. Use xterm, gterm, konsole or any other preferred terminal emulator.

Get buildfs.py first:

:~$ wget raw.githubusercontent.com/DeviationTX/de...ms/devofs/buildfs.py
:~$ md5sum buildfs.py
759d7f5ef9e075b6c2c1566fd7d8e35b buildfs.py

Here is an example:

:~$ mkdir devofs-test4Quell
:~$ cd devofs-test4Quell/
:~/devofs-test4Quell$ cp ~/devo.fs/
:~/devofs-test4Quell$ cp ~/devo.fs/devo.fs-20171219 ./
:~/devofs-test4Quell$ cp ~/devo.fs/buildfs.py ./
:~/devofs-test4Quell$ mkdir devo.fs-20171219-extraction-dir
:~/devofs-test4Quell$ python buildfs.py --fs devo.fs-20171219 --dir devo.fs-20171219-extraction-dir --extract
Warning: Spoiler! [ Click to expand ]


:~/devofs-test4Quell$ python buildfs.py --fs devo.fs-20171219-recreated4Quell --dir devo.fs-20171219-extraction-dir --create
Filesystem will use 50kB of 64kB filesystem

:~/devofs-test4Quell$ md5sum devo.fs-2017121*

i have the python shell= Python 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:19:30) [MSC v.1500 32 bit (Intel)] on win32
will that work as a terminal emulator, or notepad++, there are 2 python, python command line and IDLE python GUI.

i copy and paste the buildfs.py link you sent me but nothing works I dont know where to use it?
the examples you sent have my head spinning, i can see your putting effort in to help me but im to dumb to use it!

In Windows just use buildfs.exe in cmd.

Create a subdirectory for the extracted file system. You can do it with the explorer.
Then type something like
c:\home\quell\downloads\buildfs.exe --fs c:\devo\devo.fs --dir c:\devo\subdirectoryname -x

ok i can manualy put a fs file in my FDDESTINATION folder thats in a devo folder, with buildfs inside the devo folder also.

i can run the command line in CMD with the -x on the end and it just runs 1 second and then brings up another command start.

when i run the same command line with the -c on the end it runs for a second then says filesystem size:65552 is to large for 64k file system, so its trying!

When i run the command line with the -c on the end but no file in the FSDESTINATION folder. IT runs and says Filesystem will use 0kb of 64kb filesystem.
Soooo something is getting through, what am I doing wrong

If my radio uses the F:\ USB port to communicate to the computer so what would the command line look like to load to and from the radio with the buildfs program
I read that this may help with the fs files being slightly over 64 when transferred back and forth.

YES, everything in the devo.fs is unpacked from the radio and in my fsdestination folder.
This morning I decided to try the build fs command lines to/from the radio directly and its working.

now I just have to figure out how to add and remove Protocols and models and stuff, maybe just swap out the folders and then repack it?

getting there, thanks, everyone!

Don't add too many protocols and models, 64kb are not that much and also model.ini-files with complex mixers can become 2kb in size. When the file system is full your transmitter will not be able to save the changes. I'm glad you have found out how to use buildfs.exe.

Thanks for the advice Schuyler, I even deleted some of the models I only have 2 drones right now and all my old airplane stuff is still on the Old Airtronics 8ch 72Mhz frequency radio.
If I ever want a plane to fly I can get a new receiver for them, once I get more than 4 or 5 models I can put in the expanded memory chip I got 2 incase I screw up on one.
I spent about 2 hours putting in my NRF24L01 and it worked on my the first try on my Bayangtoys drones, they're all over the place right now but they bind and function I just have to tune it all in and set up the switches. YES, YIPPEE!

Funny thing is that 64k limit, my fist computer was a Vic 20 then I thought it was huge to be able to get the Commodore 64!
Now it's not enough for some people to fly Rc with....
