New features include: + This release adds: <ul> - <li> - Improved reliably and additional drivers for the Eagle-100 board (LM3S6918 - ARM Cortex-M3). Additional drivers include Ethernet, SSI, and support for - the on-board LEDs and microSD cards. - </li> - <li> - The SPI-based MMC/SD driver was extended to support SDHC Version 2.xx cards. - </li> + <li> + Support for the Olimex STRP711 board. That board is based on the STMicro + STR711 MCU (ARM7TDMI). Integration is complete on the basic port (boot logic, + system time, serial console). Two configurations have been verified: (1) The + board boots and passes the OS test with console output visible on UART0, and + the NuttShell (NSH) is fully functional with interrupt driven serial console. + An SPI driver is available but untested (because the Olimex card slot appears + to accept only MMC cards; I have only SD cards). Additional needed: USB and + driver, MMC integration. + </li> + <li> + Support for the CodeSourcery and devkitARM Windows-native GNU toolchains. + Makefiles have been modified for the LM3S6918, LPC2148, and STR711 to support + these toolchains under Cygwin. + </li> </ul> </p> -<p> - In addition, this release includes several important bugfixes for the LM3S6918, the LPC2148, - the SPI-based MMC/SD driver, and to FAT32.
