Hi folks, I have downloaded the source code for the AdBlocker project, by John Park. For the life of me, I cannot get it to run on the Feather ESP32 S2 TFT. The provided UF2 file works perfectly (how did they create that file? I cannot find a way which works) BUT the actual Arduino sketch project,…

Thank you, I had installed this and tried it on an exported binary in Arduino Classic IDE but the resulting uf2 file is always zero bytes. I have no idea why, but I am a controls engineer (PLC programmer) so not unfamiliar with this kind of subject matter. Using that tool seems not to work. Any ide…

[image] l-tech: tried it on an exported binary in Arduino Classic IDE did you try with the old 1.8.8 ? that's the one it was tested with

otherwise use the underlying script, see this discussion [image] Pi Pico - Generating Uf2 from Bin Microcontrollers Hi @spaceacejammer You need to run a Javascipt file called bin2uf2.js that converts the binary to the UF2 format. It's a cool feature that once you've got…

To be honest I have the older 1.8.19 and v2.1.1 but hadn't tried an older version. Do you think this is worth a try?

I really appreciate your answers. I am now setting up v 1.8.8 of the IDE and I see the chat you linked states there were issues using the uf2 tools on later builds, so that is a great starting point. Truly thankful. This has had me tearing my hair out (what is left of it) - I have never seen a syste…

[image] l-tech: I have never seen a system where later versions were not as good as the earlier ones...Arduino IDE seems to be one. yeah they made some hard choices when moving to the 2.x version and dropped support for extension as we knew them (typing from my iPhone so can't test anything) …

Here I am back at the problem I started with. Using the tool generates this error and an empty uf2 file: java.lang.NullPointerException at java.lang.Long.decode(Long.java:892) at com.makeUF2.makeUF2.makeUF2.createUF2(makeUF2.java:232) at com.makeUF2.makeUF2.makeUF2.run(makeUF2.java:290) at java…

damned... this thing is pretty old and may be you have now a newer Java runtime that introduces incompatibilities... I'd explore the source then... [image] GitHub - microsoft/uf2: UF2 file format specification UF2 file format specification. Contribute to microsoft/uf2 development by c…
