- This release adds support for two new MCU architectures in various states of development: + This release completes the verification of the basic port for the NXP + LPC3131 MCU + on the Embedded Artists EA3131 board. + This basic port includes basic boot-up, serial console, and timer interrupts. This port + has been verified on the using the NuttX OS test and includes a working + implementation of the NuttShell (NSH). +
++ An extended release will follow and should include SDIO-based SD card + support and device USB.
-- This release adds support for the SAM3U-EK development board with the - AT91SAM3U4E. - As with most NuttX architecutre releases, the release will be rolled out in - two parts: A basic port and an extended port. -
-- NuttX-5.1 includes the basic port for the SAM3U-EK board. This release - passes the NuttX OS test and is proven to have a valid OS implementation. - It supports the basic boot-up, serial console and timer interrupts. A - configuration to support the NuttShell is also included. -
-- The extended port will also include support for SDIO-based SD cards and - USB device (and possible LCD support). These extensions may or may not - happen by the Nuttx 5.2 release as my plate is kind of full now. -
-- This release also adds the complete implementation of the basic port for - the NXP LPC3131 MCU on the - Embedded Artists EA3131 - board. That port, unfortunately has stalled due to tools issues. Those tool issues have - been resolved and I am confident that the verified basic port will be - available in NuttX-5.2. -
