RE: NuttX config browser
Hi Maciej, Could you have an option to upload a defconfig to see the settings based on it?

Sure, I will add a side pane. Regarding online IDE. I was trying few times to switch to online development. The problem is that to debug or even to connect to nsh, one still needs local software and local copy of entire project. Which is against the basic reason why we would like to develop online.

RE: NuttX config browser
vscode may a good choice here: https://code.visualstudio.com/ It is totally free, open source and run on macOS/Linux/Windows Many 3rd party tool build around vscode(e.g. PlatformIO): https://platformio.org/platformio-ide And github announce a new IDE base on vscode recently: https://github.com/features/codespaces/?utm_source=announcement&utm_medium=blog&utm_campaign=satellite-product-recap The best thing is that online version has the full feature as the local version because vscode is built from JS, CSS, and HTML. > -Original Message- > From: Maciej Wójcik > Sent: Monday, June 1, 2020 11:23 AM > To: dev@nuttx.apache.org > Subject: Re: NuttX config browser > > Hello Alan, > > A suggestion: when the user click on the option it should be nice to > > see the Help for that option. > > > Sure, I will add a side pane. > > Regarding online IDE.

bug report
Hi, I found a bug at "pty.c" during ssh server implementation. When I turn on CONFIG_SERIAL_TERMIOS and OPOST|ONLCR on pty device for nsh console's stdin/stdout (ssh shell service), I've got system crash. Bugs at line 687 of pty.c, pty_write() ntotal++; when converting '\n' to '\r\n', pty_write() will return more than requested (+1, for example) length. and this will break caller lib_fflush(), line 150 of lib_libfflush.c. When she get (libfflush()) bytes_nwritten which is greater than nbuffer, nbuffer goes to negative at line 150 and eventually destroys *stream->fs_bufpos at line 163 of lib_libflush.c Removing ntotal++; line 687 of pty.c will fix this bug.
