# ESP32-C6
|
||||||
|
|
||||||
|
Template firmware for both, low-performance and high performance core of the
|
||||||
|
esp32-c6 riscv processor.
|
||||||
|
|
||||||
|
## hp-core
|
||||||
|
|
||||||
|
Firmware for the high performance core.
|
||||||
|
|
||||||
|
### Build
|
||||||
|
|
||||||
|
```shell
|
||||||
|
cargo build --package hp-core --release
|
||||||
|
```
|
||||||
|
|
||||||
|
## lp-core
|
||||||
|
|
||||||
|
Firmware for the low performance core.
|
||||||
|
|
||||||
|
### Build
|
||||||
|
|
||||||
|
```shell
|
||||||
|
cargo build --package lp-core --release
|
||||||
|
```
|
||||||
|
|
||||||
|
## Execution
|
||||||
|
|
||||||
|
```shell
|
||||||
|
cargo run --package hp-core --release
|
||||||
|
```
|
||||||
|
|
||||||
|
### Preconditions
|
||||||
|
|
||||||
|
In order to execute/flash the project some conditions must be fulfilled:
|
||||||
|
|
||||||
|
* hardware target is connected with USB before the devcontainer is launched
|
||||||
|
* the belonging tty device is named `ttyACM0` (otherwise rename it in
|
||||||
|
`.devcontainer/devcontainer.json`)
|
||||||
|
* the belonging tty device (`ttyACM0`) is member of the `root` group because
|
||||||
|
the devcontainer user (`esp`) is in this group too. If this changes it must
|
||||||
|
be adoptet in `.devcontainer/Dockerfile`
