Describe the bug

Hello, I tried to update my calculator with "make epsilon_flash", but after rebooting the calculator, it doesn't turn on or in dfu mode.

I tried again to flash and then I have : DFU epsilon_flash INFO About to flash your device.

Expected behavior

I thought it will be updated (i wanted to test the beta)

Thank you for your help !

I encountered the same problem. I could get out of it by checking out the 11.0.0 branch (or 11.1.0), then flashing from it (for it to work you have to ln -s build/device/epsilon.elf . because there is a missing path in the makefile). I'm now trying to find out when it broke, probably because the current build system expects a DFU on the calculator that is more recent than what ours have.

Thank for your answer ! I've tried to update my numworks, but it didn't want to enter in dfu mode, do you have an idea ? Thank you ! Edit : I've managed to enter in dfu with the reset button and a key.

If you manage to give me (or to commit) for resolving the issue, leave a comment ! Thank you !

I found what is happening: when I last tried to flash my device, there was only one hardware model: the N0100. Now there are two: the N0100 and the N0110, and the latter is the default. You have to use make MODEL=n0100 epsilon_flash` to get the correct version, which will flash completely. The error messages (or lack thereof) are problematic when doing the actual flash, and IMHO that is a bug to be fixed. Also, the build documentation predates the advent of the new model and it is also a bug. I will submit a PR for the build instructions, but I will not have time for the build system itself.
