This application enables USB Mass storage on the Primer2. This means that the Primer2 can be connected to a PC and you can see the content of the SD card on the PC operating system.


The code of this project is taken from the ST demo app package and ported to the Primer2.


The zip contains:

- CircleOS application that enabled USB mass storage when the application is executed. (

--> This application can be used with CircleOs v1.6 and up because it's using it's own SDIO driver (similar to the one that's used in CircleOs v3.5



- Modified version of CircleOS v3.5 with USB mass storage integrated. USB MS can be activated using the 'OS' menu. (

 --> Can be used if you want to have USB mass storage as part of the OS and want to keep debug space for other applications.
