- Use mbed OS POSIX API to write 800 KiB file to storage using 1 byte - 32KiB buffers.
- Use mbed OS FlashIAP driver to fill internal flash with data.
- Test concurrency, read data from file and write to flash.
Test:
- Filesystem:
- Write a large file to filesystem and read it back again.
- Tests filesystem works with large files.
- FlashIAP:
- Write a large file to internal flash and read it back again.
- Tests driver can write to internal flash.
- File-to-flash:
- Read a file from filesystem and store it in internal flash.
- Tests if FlashIAP and SPI can work concurrently.
- Use mbed OS TCP Socket to download file over HTTPS.
- Use mbedTLS to provide transport layer security.
Test:
- Network-http:
- Download large file over HTTP.
- Tests network robustness.
- Network-https:
- Download large file over HTTPS.
- Tests TLS robustness.
- Network-multiple-http:
- Download multiple files simultaneously over HTTP.
- Tests the network stack can service multiple sockets concurrently.
- Network-multiple-https:
- Download multiple files simultaneously over HTTPS.
- Tests the TLS stack can service multiple contexts concurrently.
- Warning This test is not enabled on IAR due to inconsistent heap configuration.
- Compile:
mbed test --compile -m TARGET -t TOOLCHAIN --app-config mbed_app.json -n "*stress*" - Run:
mbedgt -vV - Note: the tests can run for 60 minutes.

mbedgt: test case results: 52 OK

Compilation fails due to missing tls_socket.h
- If run
mbed deploycheck for any errors, if you have not installed Mercurial it cannot fetch the tls_socket.h, i.e. commandhgwill fail. - You can install Mercurial in Linux via
sudo apt-get install mercurial.
Compilation fails to various SSL-issues
- Likely the board you are trying does not have Mbed TLS entropy implemented. You can add these macro -definitions to work around that problem (but bear in mind - this is no way for a production secure solution).
"macros": [
"MBED_CONF_APP_MAIN_STACK_SIZE=10240", "MBEDTLS_NO_DEFAULT_ENTROPY_SOURCES", "MBEDTLS_TEST_NULL_ENTROPY"
You will gets lots of warning during compilation with those, though.
