The 90th release of NuttX, Version 6.23, was made on November 5, 2012,
|
||
|
|
and is available for download from the SourceForge website. Note
|
||
|
|
that release consists of two tarballs: nuttx-6.23.tar.gz and
|
||
|
|
apps-6.23.tar.gz. Both may be needed (see the top-level nuttx/README.txt
|

|
|
|
||
|
|
This release corresponds with SVN release number: r5313
|
