+

+ The release of NuttX-6.3 follows only a nines days after the release of version 6.2. + This special back-to-back release was made so that the current released version of + NuttX will correspond to the initial release from the RGMP project. +

+

+ This release adds architecture support and build configuration for RGMP. + RGMP is a project for running GPOS and RTOS simultaneously on multi-processor platforms. + See the RGMP Wiki for further information about RGMP. +

+

+ This release also includes support for STM32 FLASH, build improvements, and initial, incomplete support for the MicroChip PIC32MX MCU. + Bug fixes are included for some build problems, USB host class driver error handling, NX graphics color mapping, and problems with C standard I/O buffer flushing. + See the ChangeLog for further details. +

+

+ Release notes for version 6.2 are retained because they are still relevant. +
