History

Tobin C. Harding 94732aecbf Add patch section to test crates In order to keep the embedded and schemacs test crates building when we update their local transient dependencies we need to use a `patch` section. - For `bitcoin/embedded` add `patch` section for `internals`, `hashes` already has an entry. - For `hashes/embedded` add `patch` section for `internals`. - For `hashes/extendend_tests/schemars` add `patch` section for `internals`. FTR for direct local dependencies we use a `path` field when specifying the dependency.		2023-07-18 10:27:48 +10:00

Running

To run the embedded test, first prepare your environment:

sudo ./scripts/install-deps
rustup +nightly target add thumbv7m-none-eabi

Then:

source ./scripts/env.sh && cargo +nightly run --target thumbv7m-none-eabi

Output should be something like:

heap size 524288
secp buf size 66240
Seed WIF: L1HKVVLHXiUhecWnwFYF6L3shkf1E12HUmuZTESvBXUdx3yqVP1D
Address: bc1qpx9t9pzzl4qsydmhyt6ctrxxjd4ep549np9993

Note that this heap size is required because of the amount of stack used by libsecp256k1 when initializing a context.

Cleanup

After sourcing scripts/env.sh and before building again using another target you'll want to unset RUSTFLAGS otherwise you'll get linker errors.
