This filesystem example set currently runs only under a unix host. Most of the other examples in this repository will run under either Windows or Linux, however this set requires a special build of st-util which is not yet available for Windows, and the example code looks back to the host computer and expects to see a unix file system.

The demo will parse the file on the host and print some basic information about the file in the same terminal window used to run st-util and then exits.

stlink and st-util

If this command

st-util --semihosting

does not generate an error about an unknown option then your st-util is new enough. If you get the error, please visit github.com/texane/stlink for the latest source code.

The disk_8_partitions.img file

This example requires a file named disk_8_partitions.img. This is the target file about which the application will return some basic information. Copy the disk_8_partitions.img from testsuite/tests/disk_partitions/ in the /tmp/ directory on your host computer before you run the code.

The basics

a) In a shell window run the command

st-util --semihosting

b) Build the demo and load it onto your stm32 board.

c) Run the demo on the board and check the outputs in the shell window that you used for st-util.
