NIOS2 filesystem support

We have a system running on NIOS 2 processor with Cyclone5 FPGA and ecos RTOS. We are planning to remove the OS dependency and convert the application to baremetal. Already JFFS filesystem and FIS filesystem are being used in the application. Is there any filesystem libraries that can be used in baremetal? Files are having read and write access. Any specifc links to some examples of the usage of the same in NIOS 2 processor?

    Hello, thank you for reaching out. Libraries for file system support are available from the Zephyr project, as separate libraries, such as FatFS and LittleFS. Altera does not provide support for specific filesystems such as JFFS2.

    Would those libraries be RTOS dependent? Is there any other baremetal supported filesystem libraries?

      Nothing that a Google search would turn up. Such a library would assume an interface to a flash/block device driver. Perhaps CMSIS is an option to explore.
