[KerryRJ]

I pulled down the latest crates and successfully ran alloc and mem(thank you) but ram is now failing

Are you able to confirm it working on your side @MabezDev?

I cannot get a breakpoint at the start of main to work.

Works for me: Ignore that, was running the wrong example
cargo +esp-dev espflash --tool cargo --chip esp32 --speed 460800 --example mem --features alloc /dev/ttyUSB0

Are you enabling the external-ram feature? If you are, without psram connected that will almost certainly end in trouble :D

Scratch what I said above, not working for me either!
