Release Notes: This release adds support for the Shenzhou and Wildfire STM32 boards, a new granule-based allocator for DMA memory management, and new devices drivers for the ENC28J60 and Windbond W25 FLASH. New applications include a UDP network discovery tool and an XML RPC server. Two critical bugfixes are also included which affect FAT and networking performance. Upgrading to version 6.22 is recommended for these changes.
Release Notes: A new audio subsystem includes graphical and command line media players and a VS1053 audio CODE driver. Additional Atmel SAMA5D3x drivers: Ethernet (bot EMAC and EMAC), RTC, /dev/random, watchdog, timer/counter, ADC, touchscreen, LCD, and CAN. Support for the Olimex STM32 P207 board, the Spark core, and the Motorola C139 phone.
Release Notes: This release includes extensive new support for the Atmel SAMA5 chips: DMA, SPI, high speed SD card drivers, PIO interrupts, USB host (both OHCI and EHCI), high speed USB device, Two Wire interface (TWI), and SDRAM. New networking features include drivers for the Microchip ENCX24J600 and for the TI CC3000 wireless module. Board support for the LeafLabs Maple and Maple Mini boards was also contributed.
Release Notes: New board support: Atmel SAMAD5D3x-EK and Arduino Due. Extended board support: SAM4L Xplained I/O1, LCD1, and OLED1 modules; SAM4S Xplained on-board 1MB SRAM; SAM3U-EK Touchscreen. Freedom KL25Z SDI and TSI. New applications: Zmodem file transfers.
Release Notes: A new SMART FLASH file system, new drivers for segment LCDs, wireless modules, and LCDs, and support for lots of new boards: Atmel SAM4L Xplained Pro, Atmel SAM4L Xplained, MikroElektronika Mikromedia for STM32F4, the STMicro STM32L-Discovery, the STM32 Tiny boar, and the Pirelli DP-L10 phone.
Release Notes: This release adds verified kernel build support. In this (optional) buildmode, NuttX is built as a monolithic kernel. NuttX is built as a separate kernel mode "blob", and the applications are built as a separate user mode "blob". Extended platform support includes support for the WaveShare Open1788 (NXP LPC1788) with the LCD frame-buffer driver, SDRAM, and DMA SD card support, and support for the Kinetis L Cortex-M0+ family and a (minimal) port for the Freedom KL25Z board. Architecture support for the STMicro STM32F4727/737 has been added.
