Hello, To have usbnsh working I used, as a workaround, the implementation done in this pull request: https://github.com/apache/incubator-nuttx-apps/pull/521
In my application I don't use nsh. And USB-CDC works fine accessing directly the device. Hope it helps, Best regards, Flavio Em ter., 20 de abr. de 2021 às 19:26, Alan Carvalho de Assis <acas...@gmail.com> escreveu: > > Are you getting this error: > > "nsh> nsh: nsh_session: readline failed: 9" > > Could you please share your .config file? > > BR, > > Alan > > On 4/20/21, Max Kriegleder <max.kriegle...@gmail.com> wrote: > > Strange..
