Thanks to @errant plover & @dusk tree, the latter who, on my request, added the ESP32-S3-BOX to the list of boards for tinyuf2 I was able to build the tinyuf2 bootloader for the 'esp-box'; copy CicruitPython latest; copy and ported one of my (ongoing) projects to the 'esp-box'. For those of you who are interested. Here is the link to the repo I just published: https://github.com/PaulskPt/ESP32-S3-Box_MSFS2020_GPSout_GPRMC_and_GPGGA

hi, im currently playing with tinyuf2 and got this error while trying to compile, does anyone have solution?
sinful patrol
this test looks like it is missing the trailing all
the first one isn't a valid board name
it also looks like you are windows. I'm not sure its been compiled there

yes it is on windows
vagrant onyx
yes it is on windows
I use WSL2 on Windows to do my tinyuf2 builds.

well i can conclude that the best solution for me is to do it on linux
thx guys

Can we ask uf2-samdx1 questions here? It looks like there are changes both the Adafruit fork and the Microsoft source. Is there any reason to pick one over the other if the board is in both?

I think the Adafruit one is more geared towards working with circuitpython and Arduino
Setting up the status led with the neopixel/led and whatnot
It’s been a minute since I glanced at the Microsoft version though

I'm working with an Arduino MKR board so it might not matter. Thanks for the input.
mint gyro
Gotcha, yeah I imagine either would work.

Note for the curious: TInyUF2 does not require the back-end to be an MCU's own flash, it could be another device entirely.
This allows to use a small MCU as an UF2 bootloader for another device.

i haven't seen any convo here, just bot actions, but here is my question anyway (let me know if i should open an issue or whatever instead)
i just bought this very same board https://github.com/adafruit/tinyuf2/pull/144, is there anything missing that i could (try) implement to get it merged? 😄

start by building and testing it
I don't think its been reviewed since it is marked as wip still

Hey folks - has anyone successfully gotten both the lib\esp-idf installed and TinyUF2 building on Apple Silicon? If so, what Python version did you need to use?
I cant get the requirements.txt file installed on Python 3.9.17 (lots of getenv errors from gdbgui install, and I'm not even able to run install.sh 😦
Actually, I cant even install the requirements on an Intel Mac with Python 3.11.4

I'm able to install and build from the 4.4 release branch, but not the 4.4-beta idf in the lib/esp-idf included with TinyUF2.
But when I build from 4.4 release, it builds ok, no errors, but I get a RED LED and no mass storage drive appears.
Happens with any of my board I build for 😦
coral wind
Ok, I brute forced the lib/esp-idf install by deleting my ~/.espressif folder - but that's not really a solution as I've lost all of my other esp-idf version stuff now as the 4.4-beta version is not compatible for 4.4-release and onwards 😦
I'd be curious to heart from anyone else that has this all working nicely on a Mac? Thanks 🙂

i haven't seen any convo here, just bot actions, but here is my question anyway ...
Weird... I flashed it a couple days ago and it worked (like, screen turned on + drive showed up), didnt load any .uf2 at it (didnt have any)
I have since flashed a QMK firmware (.bin) on the board and now i tried compiling it as .uf2 but the board does nothing when i flash tinyuf2 back at it 🤔
i guess i could have damaged something with wrong firmware while getting everything on ChibiOS correctly setup.... But, since it runs QMK fine, im guessing this is some kind of bug on the tinyuf2 code for the board, any ideas where/what to look at?

Hi I'm trying to build the tinyuf2 boatloader for a new esp32s2 based board. Installed everything and first tried to compile one of the existing boards but I always ran into the following error. Directory specified in EXTRA_COMPONENT_DIRS doesn't exist: /Users/x/Documents/Github/tinyuf2/ports/espressif/bootloader_components it seems like the CMakeList.txt file was changed in the last 2 weeks: https://github.com/adafruit/tinyuf2/commit/c704e12e1ab70c5a746a4d7f7a397604e2c8a387
Did I missed something to install?

i have an esp32 S3 board. I've been just compiling binaries from Arduino ide but flashing them one by one seems to be quite a lot of work (compared to uf2) so i was wondering can i use tinyuf2 to share my compiled binaries in uf2 format like the pico does?

Yup! the UF2 repo has a script that can covert from bin to uf2

thanks, ill try it
should i just need to convert the app bin?
right now im looking at uf2 enabled boards from adafruit, and they only produce app, partitions, and the bootloader

this is the flashing command from the arduino ide for the qtpy

I bet you only need to include Blink.ino.bin
the rest should already be on the board
magic cairn
I bet you only need to include Blink.ino.bin
ah also the double reset doesnt work for some reason
im assuming i just press the boot0 2 times?

I bet you only need to include Blink.ino.bin
we'll see

it is double reset on boards that have an extra cap to support it. otherwise reset and then boot0 when led is purple

i dont have an adafruit board by the way, only the devkit m
magic cairn
ok ill investigate this more
sinful patrol
make sure you give the converter the right magic number (can't remember what it is called)
there is a number used to say what platform a uf2 is for
and the file will be ignored if it doesn't match
magic cairn
HA!
found the solution
all of the details for using the uf2 converter are in there
havent tried yet with arduino ide, but with esp-idf v5.2.1 it works great 🙂
@sinful patrol thank you for your help again

Are there any plans to publish a new TinyUF2 release on github in the near future? We integrated our board last year and also adopted CP but as there is no release with the board so far nice features such as installing through the CP website or downloading the UF2 Bootloader from here: https://circuitpython.org/board/sensebox_mcu_esp32s2/ is not working
sinful patrol
looks at who releases tinyuf2 usually

Hey @lone hinge - I add board support for my new FeatherS3 Neo for tinyuf2, and I want to raise a PR, but I cant find where to add my board to the github build action - is tinyuf2 not using a build list anymore? Any idea?

Thach reworked the CI, if I remember right. It may just build all the boards in the boards directory now.

Oh, fantastic. I've really been absent from all of this for a while, so have no idea what's what! Thanks for the info 🙂

it may just be that the file is link need to be renamed

going further with the reaserch I found that "Lolin S3" "lolin S3 Pro" and "Lolin S3 mini" may be 3 different designs and need different tinyuf2 after all. I have checked the PID VID and found that S3 pro and mini have the same id
