not now best wishes ben bin.w...@qkmtech.com From: ThomasDörfler Date: 2018-01-30 15:02 To: bin wang; rtems-us...@rtems.org Subject: Re: jffs2 summary problem Hello Ben, the RTEMS community is always happy to see the functionality growning, especially with additions, which are useful to real life applications.In general I think there are three options to add missing functionality to the RTEMS ecosystem: 1.) invest your own expertise and time to get it done and to get it integrated 2.) find someone who has spare time to do it 3.) fund the corresponding work with the money required If a faster startup of the existing jffs2 RTEMS port is crucial for you, option 3 may be interesting for you. Among others, we at embedded brains can create a quote for you for commercial support, with the goal to get the corresponding functionality ported and integrated. Please let me know if this is interesting for you. Kind regards, Thomas.
