A few issues:

  1. Your ‘expected file size is 185’ is wrong. Much too small. Should be >3MB for current firmware. Perhaps your URL path is incorrect, or some other issue with the download from the web server.

  2. You need to update your ESP IDF tools crosstool-ng to 1.22.0-97. That is in the xtensa-esp32-elf package. Run 'xtensa-esp32-elf-gcc -v’ to see your current version.

Regards, Mark.

Hello All,

Been trying to get Amperae support working. Did some work in the config and tried to upload this to the module but it failed.
I do not know what went wrong.
Followed the developers guide.
Any advice welcome.

Edwin
