for nrf52840, we need this change in libtock-rs twilfredo/libtock-rs@924d277

Do you think we could upstream something like this for the above:

    #[cfg(feature = "default_layout")]
    ("nrf52840"           , "0x00040000", "768K"     , "0x20008000", "56K"    ),
    #[cfg(feature = "big_heap")]
    ("nrf52840"           , "0x00040000", "768K"     , "0x20010000", "128K"    ),

The RAM size in libtock-rs should match the board. So if there is 128K of RAM we can update it in libtock-rs, no need for a cfg flag

I thought this was the RAM size allocated for the app slice, so if we bump it to the max size then only 1 app can be loaded at a time. Is that wrong?

That would depend on the board. If one app uses all the RAM then yes, you can only have one. But I don't think there is any point in artificially limiting application sizes. We can only run a single libtock-rs application anyway (without modifying addresses).

okay sounds good, I'll send a patch.

Do you wanna bump this commit to the latest latest master, it has the RNG api that just merged?
