wolfTPM Examples
----------------
Several wolfTPM example application recipes are included in this layer. These include:
TODO
The recipes for these applications are located at:
```
meta-wolfssl/recipes-wolfssl/wolftpm/wolftpm_%.bbappend
```
This can be compiled with bitbake using:
```
$ bitbake wolftpm
```
To install wolfTPM examples into your image, you will need to edit your
"build/conf/local.conf" file with the neccesary options. There are two
steps needed in order to install wolfTPM's examples into your image.
1. You need to first add wolfTPM to your "IMAGE_INSTALL" variable like so:
- For Dunfell and newer versions of Yocto
```
IMAGE_INSTALL:append = " wolftpm "
```
- For versions of Yocto older than Dunfell
```
IMAGE_INSTALL_append = " wolftpm "
```
When your image builds, these will be installed to the '/usr/bin' system
directory. When inside your executing image, you can run them from the
terminal.
2. You then need to enable the examples in your image by
setting `ENABLE_WOLFTPM_EXAMPLES` to 1 in your local.conf like so:
```
ENABLE_WOLFTPM_EXAMPLES = "1"
```
wolfProvider
------------
To build wolfProvider view the instructions in this [README](recipes-wolfssl/wolfprovider/README.md)

wolfTPM Examples
================
Several wolfTPM example applications are included
in this layer, these include:
- attestation
- endorsement
- keygen
- pcr
- seal
- bench
- firmware
- management
- pkcs7
- timestamp
- boot
- gpio
- native
- tls
- wrap
- csr
- nvram
The recipe for these applications is located at:
```
meta-wolfssl/recipes-examples/wolftpm/wolftpm_%.bbappend
```
This can be compiled with bitbake using:
```
$ bitbake wolftpm
```
To install these applications into your image,
you will need to edit your "build/conf/local.conf"
file and add them to the "IMAGE_INSTALL" variable
like so:
- For Dunfell and newer versions of Yocto
```
IMAGE_INSTALL:append = " wolftpm "
```
- For versions of Yocto older than Dunfell
```
IMAGE_INSTALL_append = " wolftpm "
```
When your image builds, these will be installed
to the `/usr/bin/examples` system directory. When
inside your executing image, you can run them from
the terminal.
The examples can be excluded from your build by
deleting the recipe `wolftpm_%bbappend`.
Refer to the [wolfTPM Examples README](https://github.com/wolfSSL/wolfTPM/blob/master/examples/README.md)
for more information on the examples directory.
Refer to the [meta-wolfssl README](https://github.com/wolfSSL/meta-wolfssl/blob/master/README.md)
for more information on setting up your layer.
