Programming and developing for P2 from an rpi

moony

My personal desktop happens to be a travel up a flight of stairs from the garage I do things in, so I was wondering if I can reasonably expect some of the P2's tooling to work on a Raspberry Pi 3 B+
I can live without one of the various IDEs, I'm more interested in if I can expect flexcc/flexspin and loadp2 to work.

Yes, the flex tools should work fine on a raspberry pi, although you'll have to build them yourself from source. Even the GUI (FlexProp) should work, since it's in Tcl and I'm pretty sure tcl/tk is available for the rpi.

I am hoping that whoever does this, and gets positive results, will provide a highly specific and detailed set of instructions. Just saying "Oh just get the source and type in make", will not suffice for the majority audience, especially if you are working with a Raspberry Pi. I believe there is a lot more to it than meets the eye.

Would love to try out the Flex tools on RPi. Currently using PropellerIDE on an RPi 400, and finding it to be a bit quirky. It seems like the cursor occasionally jumps to a random location in the source code and places keyboard presses there while still displaying the original text. Very disconcerting.

Other than a few requirements (make sure your RPi can execute git and has an installed tcl & bison), it's quite simple to clone the repository, build and run flexprop. All this can be done in the RPi Terminal...

EDIT: latest RPi fresh install tested and the following was needed:

The current RPi OS does not contain tcl, needed by flexprop, it is this easy to install it:

$ sudo apt-get update
$ sudo apt-get install tcl tk

The current RPi OS does not contain bison, needed by flexprop, it is this easy to install it:

$ sudo apt-get update
$ sudo apt-get install bison

If the current RPi OS does not contain git (doubtful), install with:

$ sudo apt-get install git

To clone flexprop (start within a directory where you store sources i.e. $ mkdir src ; $ cd src):

$ git clone --recursive https://github.com/totalspectrum/flexprop.git

To build flexprop:

$ cd flexprop
$ make install

To run flexprop:

$ cd ~/flexprop
$ ./flexprop.tcl

OR

$ wish ./flexprop.tcl     <== wish should have been installed with tcl

To keep up-to-date with flexprop's latest sources:

$ cd src/flexprop    <== OR where ever you store the flexprop source directory
$ git pull
$ git submodule update
$ make clean
$ make install

I may have over-simplified a bit, but you can always return here and post any problems that come up...

I got FlexSpin to work on a RasPi Zero...
Some notes here: http://www.rayslogic.com/Propeller2/RaspberryPiZeroW.html

But, @dgately's post looks better...

Thanks for the 'easy to follow' directions. I now have FlexSpin running on a RasPi 400.

Thanks dgately, I just installed it on my RPi4, everything worked as expected.

Since I have SimpleIDE installed and I had to join dialout, is that also required for a FlexProp installation? Has anybody figured out to place FlexProp in the Programing Menu.

Since ersmith has been doing quite a few updates, would it be worthwhile to come up with some kind of automated update program. Any bash experts of maybe Python script experts to create such a program. Probably the best solution would be for FlexProp, itself to have an update provision.

For the new people ersmith has a Patreon and a Paypal account for those of us that might be inclined to show their appreciation for the hard work that ersmith is doing. I am a Patreon account donor.

Anyone having this issue with Flexprop in Raspberry Pi 400?
It started showing after opening more than one tab.



Error message:

@jrullan : that's a new one to me. Could you try changing line 48 of flexprop/src/balloon.tcl to add "-nocommand" after the "subst"? The revised version should read:

  pack [label $t.l -text [subst -nocommand $msg] -bg yellow -font {Helvetica 9}]\

That may help -- please let me know if it does.

Today I did a PropWare update on the RPi 4, using "git clone --recursive https://github.com/totalspectrum/flexprop.git", this only works if the flexprop folder is empty. Is there another command that just overwrites what is in the flexprop folder, or is the preferred method to work with a clean folder.

Ray

dgately

If you already have cloned flexprop, you should not use clone again...

To update to the current repository revision:

cd PATH_TO_YOUR_SOURCES/flexprop
git pull
git submodule update
make clean
make install

@ersmith Yes, it did work! The error is not showing anymore. Thanks and sorry for the late reply, I did not have time this week for the follow up.

Do you know what could be the cause of this error I am having when compiling with debug enabled?:

As per instructions of @ersmith, fixed it by running the make install command specifying the directory where I cloned the repo:

make install INSTALL=/home/pi/Downloads/flexprop

This fixed it.

I'm trying to install flexprop on a raspberry pi. dgately's post above was very helpful but after install i'm getting a warning: openspin not found , P1 loader is not built. I need the P1 support. My question is where do I put openspin. (I believe it is a single file)

ersmith

Build openspin by cloning https://github.com/parallaxinc/openspin and then making it. The final program ends up in build/openspin. Just copy that to anywhere on your PATH. I think the steps would be something like:

git clone https://github.com/parallaxinc/openspin
cd openspin
make
sudo cp build/openspin /usr/local/bin
