Ethernut 5
This is the first Ethernut Board based on an ARM9 CPU. Beside Nut/OS it is capable of running Linux.
Status
24th of February, 2009.
Software
Ole Reinhardt just finished the Linux Board Support Package (BSP), consisting of the following components:
- U-Boot bootloader, which can boot Linux and NutOS.
- Linux kernel 2.6.28 supporting NAND flash, Dataflash, Ethernet, MMC, RTC, I2C and SPI interfaces, etc...
- Ångström Linux distribution, based on OpenEmbedded supporting a full featured Linux userland.
Hardware
Four prototypes had been build, out of which three are working, more or less. First production will be done by egnite GmbH, but is waiting for delivery of Atmel's AT91SAM9XE512. So far, no delivery date had been confirmed.
egnite didn't published any price information, but the single quantity price is expected being below 200 Euro.
