Re: How can I get a single .bin when building uPy for an ESP32-s3 from source?
I am just going to post my own reply. While the idf.py tool produces the esptool.py command I pasted above, which uses the 3 separate bin objects. There is also a firmware.bin that gets built by the makeimg.py preceding the idf.py build command in the make file So it's sufficient to use: esptool.py ...

Re: Flashing instruction for ESP32-S3
Nope, the generic binaries don't support the 8MB PSRAM variant because these need to address the RAM differently (octal instead of quad). Therefore you have to build your own firmware. Note as well, that you should disable the USB support for now because otherwise you won't get the REPL on the stan...

How can I get a single .bin when building uPy for an ESP32-s3 from source?
So I have had no luck getting the ESP32-S3 binary available on the downloads page working for my ESP32-S3-DevKitC-1-N8R8 Development Board. Following others' instructions, I have gotten a successful build from source. This required using an Ubuntu VM. I tried using the Espressif Docker container, bu...

Re: Problems with ESP32-s3
So I have a ESP32-S3-WROOM-1 N8R8 DevKitC-1 that I can't seem to get to work with the generic binaries. Is building from source the only option I have to use Micropython on the ESP32-S3? Is there not a matrix that could be added to build a couple of standard generic binaries to support the common fl...

Re: Flashing instruction for ESP32-S3
Yes, I agree those instructions appear to be wrong.
@Detlev did you by chance use the Generic binary(ies) provided from the downloads page for your installation? I have a ESP32-S3-WROOM-1 N8R8 that I can't seem to get to work with the generic binaries.

Re: Teensy 4.0 & 4.1
Is there support for CAN Bus in the micropython Teensy 4.x support?

Re: Teensy 4.0 & 4.1
You cannot upload .bin files to the Teensy devices, since the built-in loader (call Half-Kay loader by PJRC) expects the .hex transfer format. The loader will convert that to binary, such that in the end all load formats create the same binary image in the MCU memory. Ok, yeah I couldn’t find any d...

@Roberthh
Could you provide some instruction on how to use the .bin file you referenced in the downloads like above with my teensy 4.0 board? I built the port from source and used the .hex file that was produced, but I can't seem to find anything on uploading a .bin to a Teensy 4.x board.

What are the uPy differences/implications between .bin, .hex, .elf, .map, .dfu firmware?
I am looking at https://micropython.org/download/all/ for the ESP32 in particular, but really my question is more general about all the artifact types. What are the differences between .bin, .hex, .elf, .map, .dfu artifacts? I can Wikipedia the file types and get the idea that yeah .bin is a binary ...

Re: Teensy 4.0 & 4.1
Thanks, @Roberthh. When I wrote this I had no idea that there were binaries for all the ports. I've changed the intro of my article accordingly.Roberthh wrote: ↑Sun Jul 25, 2021 3:05 pmA daily build is supposed to be at https://micropython.org/download/all/. Obviously that does not contain the features that are under construction.
