RE: [EXT] Re: RPMsg FS on NuttX and Linux
Hi Bowen, It seems that the attachment didn’t come through. Could you send them again? For us it is sufficient that Linux can host the server side. The goal is to supply some storage space to Nuttx and our system (i.MX95) does not have any physical storage attached to the NuttX core.

When in doubt, report the message using the 'Report this email' button Hi Andre, The attachment is the patch for rpmsgfs, we only implement the rpmsgfs server side in linux for now, rpmsgfs client side in linux is still under development. So we can access the Linux‘s file system in NuttX, but in Linux, we can't mount the Vela's file system.

RPMsg FS on NuttX and Linux
Hi, I am searching for a solution to share a disk or directory on a Linux host and make it accessible in NuttX through RPMsg. It looks like CONFIG_FS_RPMSGFS is the feature I need. According to this NuttX channel video (https://www.youtube.com/watch?v=-YLAQlJR1vA) various RPMsg services in Nuttx are supported in Linux including RPMsg FS. So, I tried setting this up but couldn’t find the correct linux module that is able to interact with this service. When I try to mount a directory with nsh> mount -t rpmsgfs -o cpu=netcore,fs=/mnt /mnt Some interaction happens. See linux dmesg log: [ 61.086471] virtio_rpmsg_bus virtio0: creating channel rpmsgfs-0x2000c1c8 addr 0x401 But it seems no linux driver is listening to that channel. When I try to access the mounted directory in NuttX then nsh freezes. What do I need to do on Linux to support this service? Do I maybe need a patch or a different fork? Kind regards, Andre

Thanks! I got it to work on the imx8mp. Do you know if there are any plans to upstream this driver to mainline linux?

uart rpmsg driver compatibility
Hi, Does the NuttX uart_rpmsg.c driver have a Linux counterpart to interact with? I want to achieve a virtual uart connection through rpmsg on an imx8mp between NuttX (m7) and Linux (a53). The tty_rpmsg.c driver in mainline linux does not seem compatible as it read and writes the raw data directly from the rpmsg buffers. Whereas the NuttX driver uses a struct ‘uart_rpmsg_write_s’ which contains the raw data in one of its fields. Kind regards, Andre
