boards.txt references nonexistent file Caterina-Lora32u4.hex

[inactivist]

The boards.txt file references a non-existent file. Is there a way to acquire it, or is it unnecessary?

When I try to upload a sketch, I see this error message:

Bootloader file specified but missing: /home/user/arduino/arduino-1.8.5/hardware/BSFrance-avr/avr/bootloaders/caterina/Caterina-Lora32u4.hex

boards.txt:

I am facing the same issue. I am using a LoRa32u4 II board, Arduino IDE 1.8.6, on a Windows 10 machine. The strangest thing is that it (the example programs with the BSFrance LoRa libraries) were working until a few days ago. This morning it just stopped working. Between then and now the only thing I have done is install two extra libraries (OneWire and DallasTemperature) for reading a particular sensor using another Ardunio Uno board.

I was able to program the board successfully (I ignore the warning). It's only a problem when you try to program (upload) the bootloader (?).

IIRC other people have observed that you can treat these as an Adafruit Feather 32u4 board, though I've not tried it. Interestingly, the code contains references to Adafruit product:

I found the .hex file in http://bsfrance.fr/documentation/11355_LORA32U4II/BSFrance.zip (link on product page https://bsfrance.fr/lora-long-range/1345-LoRa32u4-II-Lora-LiPo-Atmega32u4-SX1276-HPD13-868MHZ-EU-Antenna.html)

Does anyone have any alternate locations to obtain this BSFrance.zip file? I have been trying the bsfrance.fr site for two weeks now and it throws a 503 bad gateway error.

Please, give a some mirror link for BSFrance.zip.
Thanks a lot!!!!

Hello all,

I have a copy of hex files for both Lora32u4 on my PC, please find the archive,

I found the .hex file in http://bsfrance.fr/documentation/11355_LORA32U4II/BSFrance.zip (link on product page https://bsfrance.fr/lora-long-range/1345-LoRa32u4-II-Lora-LiPo-Atmega32u4-SX1276-HPD13-868MHZ-EU-Antenna.html)

FWIW, archived on archive.org:

The BSFrance.zip file isn't on archive.org as far as I can tell. I've attached my copy here as well, for archival purposes.
