LittleFS port to Teensy/SPIFlash

dirkenstein · Oct 16, 2019

I have a crude proof-of-concept port of the ESP8266 implementation of LittleFS to Teensy using SPIFlash.

Except for the fact that the included SPIFlash library seems to hang with my 8Mbit Winbond chip (I had to use the version from GitHub) everything appears to work on a first pass.

Is there any use/need for this more generally? I was looking to use it to store log files (lots of file appends).

I have switched from the NodeMCU to the Teensy 4.1 and would love to have a file system like on the ESP8266 for an Ethernet web server so I can store all of my JavaScript gauges and such.

Yes. I was planning on working with LittleFS sometime "soon"...

Curious to see what you've done, if you're willing to share.

Good info going to keep an eye as well. If you care to share you code it would be great.

Thanks its a great starting point for the Teensy.

Ok was playing around with speedtest example and am getting a bunch of errors if i just copy the libs into the libraries folder. (downloaded SPImemory from your repository on github. So what is the install process and the example I should be playing with.

dirkenstein · Nov 4, 2020

Sorry, the examples are not up to date. They need some namespace /include file logic adding.
I will copy fixed versions in tonight, as well as a complex example program that uses both SDFS and LittleFS.

The SPIMMemory version in my repo hasn't eean updated with my changes yet.

Thanks. Kind of figured it was a namespace issue when I was digging into the error messages. Was just curious about how you set it up, etc. It did help already even with the error messages I got

No real rush - just my curiosity got to me

This will be interesting. Also wondering if this will be mainly for external storage?

I still keep thinking if most of my program don't exceed 1MB... And the T4 has 2 and T4.1 has 8 and the MM? maybe 16. Would be great if one could create a drive without needing additional hardware.

For sure will be following along. And great work!

If I read the ESP8266 docs correctly you should be able to set up the pointer defined to what internal or external flash. For instance in the case above its pointer to class SPIFlash which does the defines for:

Look kind of familiar. Most of those functions I have already available for the QSPI Flash or easily ported back. A few additional ones would have to be added but very doable. Good thing I play around so much with the flash library. So instead of pointing to the SPIflash with could point it to a QSPIflash lib for the T4.1 at least.

just for the record, a while back (see old thread), I managed to get adafruit's FatFs lib to work on SPI flash on Teensy prop shield with Teensy 3.2.

http://elm-chan.org/fsw/ff/00index_e.html fatfs (deprecated?), now https://github.com/adafruit/SdFat

Don't remember that old thread (only 2 years old) but I did come across the Adafruit SPIflash library when we first started playing with SPIFFS. As you said not sure you want to use FatFS:

Of course there are a lot of arguments of why you wouldn't the overhead of FatFs on an embedded SPI serial flash ...

But its always an option. Think its going to Paul's call in the end. Know for the NAND chip not sure FatFS or LittleFS is going to be the way to go from what I was reading.

dirkenstein · Nov 4, 2020

LittleFS examples updated to support Teensy. now in the repo.
Oh, and BTW the BD directory in littlefs needs to be removed as it doesn't compile under teensy.

Thank you for the update. Did you update SPIMemory as well, you mentioned that the you had wasn't updated.

mjs513 · Nov 4, 2020

Just downloaded your latest libraries and tried a compile for your listfiles examples in the littlefs-teensy directory and still the errors I mentioned before. I am using beta4 of TD on a T4.1 for testing. This time I am listing them for you to see what I am seeing:

Installed a fresh 1.8.13 IDE folder with TS_1.54b4 and made a PORTABLE subfolder and put the four @dirkenstein libraries for littleFS there.

<edit> :: Seeing this now ... "It also needs an updated SPIMemory library which i will place on GitHub ASAP"
github.com/dirkenstein/SPIMemory

>> and todo this : "the BD directory in littlefs needs to be removed as it doesn't compile under teensy."
>This seems to be gone now?

I get this:

Code:

In file included from T:\arduino-1.8.13_p54\portable\sketchbook\libraries\LittleFS-Teensy-master\examples\listfiles\listfiles.ino:20:0:

Error compiling for board Teensy 4.1.

Not sure yet where this is to come from for :: T:\arduino-1.8.13_p54\portable\sketchbook\libraries\LittleFS-Teensy-master\examples\listfiles\listfiles.ino

Code:

#include <LittleFS.h>
#include <SPI.h>
#include <[B]SPIMemory.h[/B]>

@mjs513: Note I tried this with 'portable' in Tset (changed compile.cmd path there :set arduino=T:\arduino-1.8.13_p54) and it doesn't seem to redirect to :: portable\sketchbook\libraries
>tset edit pending just alter lib folder ...

Okay SPIMemory resolved.

Had to Move 'littlefs' to :: portable\sketchbook\libraries\LittleFS-Teensy\src\lib\littlefs

@dirkenstein: @mjs513 or myself could EDIT post #1 to add setup/install steps including all the github and setup needed

Now I seem to be getting the same error list @mjs513 presented above:

Just wanted to confirm the stock SPIMemory should work for you.

Are you trying to compile this on a teensy 3? I think that may not work as there is already an FS.h header in the core library.

I found no SPIMemory.h file on this system? Did a search ( before reading above post ) and found one on github - then used one above.

This is building for a T_4.1 with TeensyDuino 1.54 Beta 4. In this version I see FS.H in BOTH Teensy3 and Teensy4 CORES folders.

It may be new - but it is coming/changing as Paul is incorporating SdFat-Beta code to replace the use of prior "SD" code that is going away.

I need to push an SPIMemory update before this will work.
Are you trying to compile this on a teensy 3? I think that may not work as there is already an FS.h header in the core library and all my tests and define checks are against teensy 4.

You need the SPIMemory version in my GitHub repository (now updated to actually work).

OK- I think I know what this is.

You either need to rename my FS-Teensy files to something the FS-Test.h and update both littlefs and sdfs to use the new names or just temporarily delete/remove FS.h from the teensy directory- It's not used by anything anyway yet.

Morning all
Just got my coffee so ...

I just downloaded the updated SPIMemory and:
1. it compiles for the T4.0 and T4.1 when using TD1.53
2. getting the same errors as posted when I use TD1.54-beta4
3. temporarily deleted SD and SDFat from the Teensy Libraries folder and recompiled under TD1.54-beta4 but still get the errors as noted by @defragster and myself.

Note: Good point about the FS.h conflict. Need to change that anyway,

Wonder where the issue is coming from.

On the off chance that there was some other strange conflict with FS with the libs I took updated all the files using FS.h to FS_ls.h and now it compiles under TD1.54-beta4!
