# Silicon Labs Simplicity Studio
|
|
|
|
Tested with ERF32xG21 Starter Kit and Gecko SDK v3.2.2 and v4.2.3.
|
|
|
|
## Simplicity Studio Example
|
|
|
|
Based on `cli_kernel_freertos`.
|
|
* Create a new example project for your board based on the CLI FreeRTOS example.
|
|
* Create a new `wolfssl` and put wolfSSL into it. Tip: Use `./scripts/makedistsmall.sh` to produce a reduced bundle.
|
|
* Exclude (or delete) all .S and asm.c files.
|
|
* Exclude (or delete) directory not used (only the `src`, `wolfcrypt` and `wolfssl` directory are used).
|
|
* Add the `IDE/SimplicityStudio/user_settings.h` into `wolfssl/user_settings.h`.
|
|
* Add the `IDE/SimplicityStudio/test_wolf.c` to the project root.
|
|
* Add C preprocessor `WOLFSSL_USER_SETTINGS`.
|
|
* Add C include path `wolfssl`.
|
|
* Disable UART flow control: `config/sl_iostream_usart_vcom_config.h` -> `#define SL_IOSTREAM_USART_VCOM_FLOW_CONTROL_TYPE usartHwFlowControlNone`
|
|
* Adjust stack and heap to larger size 12KB:
|
|
- Adjust the CLI stack. Edit `config/sl_cli_config_inst.h` to `#define SL_CLI_INST_TASK_STACK_SIZE (12*1024)`
|
|
- Adjust the FreeRTOS heap. Edit `config/FreeRTOSConfig.h` to `#define configTOTAL_HEAP_SIZE (12*1024)`
|
|
* Add the following code to `cli.c`:
|
|
|
|
```c
|
|
extern void wolf_test(sl_cli_command_arg_t *arguments);
|
|
extern void wolf_bench(sl_cli_command_arg_t *arguments);
|
|
|
|
static const sl_cli_command_info_t cmd_wolf_test =
|
|
SL_CLI_COMMAND(wolf_test, "Run wolfCrypt tests", "",
|
|
{ SL_CLI_ARG_WILDCARD, SL_CLI_ARG_END, });
|
|
|
|
static const sl_cli_command_info_t cmd_wolf_bench =
|
|
SL_CLI_COMMAND(wolf_bench, "Run wolfCrypt benchmarks", "",
|
|
{ SL_CLI_ARG_WILDCARD, SL_CLI_ARG_END, });
|
|
|
|
static sl_cli_command_entry_t a_table[] = {
|
|
{ "wolf_test", &cmd_wolf_test, false },
|
|
{ "wolf_bench", &cmd_wolf_bench, false },
|
|
{ NULL, NULL, false },
|
|
};
|
|
```
|
|
|
|
* If running wolfCrypt benchmark enable printf float
|
|
- `C/C++ Build Settings` -> `Settings` -> `Tool Settings` -> `GNU ARM C Linker` -> `General` -> `C Library "Printf float"`.
|
|
|
|
## SE Manager
|
|
|
|
For SE Manager cryptography hardware acceleration see [/wolfcrypt/src/port/silabs/README.md](/wolfcrypt/src/port/silabs/README.md).
|
|
|
|
Enabled with `WOLFSSL_SILABS_SE_ACCEL`. Requires the "SE Manager" component to be installed.
|
|
|
|
## Benchmarks with SE Accel
|
|
|
|
Tested on ERF32xG21 Starter Kit (Cortex M33 at 80 MHz) and Gecko SDK v3.2.2 (-Os).
