tcalI'm going through the Fomu workshop.  There's  a Rust example.   The size of the final .dfu binary seems to have exploded.   It's now at ~256MB, while it used to be under 5kB!   I can provide more details of my investigation, but hopefully this is a known (& solved?) problem.   I'm assuming it's due to some segment offset that has changed or something like that.22:17

tcalI have cargo version 1.45.1.    I'm cross compiling to riscv32i.   The output from cargo, riskv-rust-blink, is roughly the same size (150kB-200kB).   But before, I could strip that file and get down to 6kB.   Now, I get this message: `warning: allocated section `.stack' not in segment`, and the size is reduced only to 137kB.    Or, if I perform the objcopy command from the flash.sh script, the resulting file `fomu-rust.bin`23:06
tcalhas size 137kB on disk, but logical size 268,698,924!23:06
