Hi,
The use of A and B in sender.py is a little unclear, can there be some more information on this either in the sample or readme?

I've setup every tool on my native environment and everything works fine on the board until I try to read or write from/to the card. In case of writing, the message "Waiting to program" is on the display and the led is flashing (just like the tutorial) but when I get the card closer nothing happens.

Hi ESC Team,
we have encountered a challenge where we found multiple solutions for p which solve the challenge with different hashes.

What would be the proper way to report this?

Hey, We've discovered that the hash that we get when running sender.py differed from the one shown in the video.

Is the file shown in the video the same as available in the repository, because as far as we can tell it looks equal.

We would like to reproduce the same hash to make sure that everything is working indeed as intended.

Many thanks,
Albsociety

Hi, is the binary on this repository the correct one?

It looks like a dummy x86_64 ELF, not an AVR firmware

This is to inform you that we are facing an issue with the ESC 19 board that is provided. On connecting the provided setup to the USB port of the computer, the display isn't working. Furthermore, on trying to install the avrLoader.sh provided, we get the following errors:

Hello, is it possible to clarify some points about the deliverables?

1. Are the video and presentation due the 1st of November or they can be submitted at a later date?
2. What should be the content of the video?
   Should it be a demo of a solution?
   Can we include footage of us while we were working on the challenges?
3. What should be the content of the presentation?
   Since we only have 8 slides, can we present only one or two challenges that we found more interesting to showcase?

Thank you

Hey, could we just get the files that are inside the virtual, so we could run it on our own distros?

Thanks
