First thing we need to do is to erase the Flash partition we are going to use for the JFFS2 file system:. Cleanmarker written at 5c We can now mount the newly created JFFS2 file system. As expected, it is empty at this time:. Or, if the STM32F7 is not connected to a host at the time the above command is run, simply connect it to a host using an appropriate USB cable. At this point the STM32F7 should become visible as a USB storage device to the host, however the storage still needs to be formatted as a FAT32 file system to allow using it with standard host software.
The formatting is done on the host using standard software. For instance, on a Windows machine, go to My Computer and then locate an icon for the new removable disk. Ask to format it and agree with anything that Windows suggests, until the storage is formatted as a FAT32 file system. Ok, so now everything is ready to start deploying the STM32F7 as a "data harvesting" device. For the sake of running a clean test, let's power-cycle the device. As expected, Linux comes up to the shell:.
Next step is to associate the backing file with a loopback block device, which allows us to mount a FAT32 file system on the backing file:.
Let's "harvest" some data and store what is collected into a file in the FAT32 file system. In this demo, we emulate a data stream by taking a snapshot of the system time each second:. A message like this will appear on the target console when a connection to the host has been made:. Data collected on the target can be copied to other host disks for further processing.
Note that the format of Windows and Unix text files differs slightly. As a consequence, some Windows applications will not show the line breaks in Unix-format files. Assuming that data is stored in a text file vs a binary file and Windows is a data processing host, Linux data harvesting applications should take care of the difference by adding a carriage return character to data logs.
