A fatal error occurred: File binary.hex (length 8458352) at offset 0 will not fit in 4194304 bytes of flash. Use --flash_size argument, or change flashing address.
make: *** [Makefile:27: flash-app] Error 2

I was just trying to build the console example on libtock-rs for my ESP32-C3 board with 4MB of flash, but it seems like I need the 16MB one?! (8458352 bytes is over 8 MiB as well)
