| NuttX-9.0.0 |
| ----------- |
| |
| This is the first release of NuttX as Apache NuttX (Incubating) and represents our first major milestone as a Podling of the Apache Software Foundation's Incubator. This release is the culmination of nearly 6 months of hard work and includes several new architectures and drivers, and numerous improvements and bug fixes to the core RTOS, drivers, and networking subsystems. |
| |
| * Major Changes to Core OS |
| * Bugfixes |
| - nxsem_wait_uninterruptible() now returns if the task is canceled. |
| - Fix a bug in pthread_condwait() that was improperly re-initializing the mutex. |
| - In sched_setpriority(), fix functions called inside a DEBUGASSERT that were eliminated when assertions are disable |
| |
| * Compatibility Concerns |
| |
| - The configuration option CONFIG_CAN_PASS_STRUCT is now removed. Previously, it was used (at the cost of breaking standards support) to support older versions of the SDCC compiler that couldn't pass structs/unions as functions' parameters. A newer version of the compiler has resolved the issue. |
| |
| * Major Changes to Build System |
| - Add a post-build function that allows extending the build with CPU/board-specific logic. |
