| U-Boot port on the LEOX's ELPT860 CPU board |
| ------------------------------------------- |
| |
| LEOX.org is about the development of free hardware and software resources |
| for system on chip. |
| |
| For more information, contact The LEOX team <team@leox.org> |

| 1) Get the last stable release from denx.de: |
| o ftp://ftp.denx.de/pub/u-boot/u-boot-0.2.0.tar.bz2 |
| 2) Get the current CVS snapshot: |
| o cvs -d:pserver:anonymous@cvs.u-boot.sourceforge.net:/cvsroot/u-boot login |

| ============================================================================= |
| |
| The ELPT860 CPU board has the following features: |
| |
| Processor: - MPC860T @ 50MHz |
| - PowerPC Core |
| - 65 MIPS |
| - Caches: D->4KB, I->4KB |
| - CPM: 4 SCCs, 2 SMCs |
| - Ethernet 10/100 |
| - SPI, I2C, PCMCIA, Parallel |
| |
| CPU board: - DRAM: 16 MB |
| - FLASH: 512 KB + (2 * 4 MB) |
| - NVRAM: 128 KB |
| - 1 Serial link |
| - 2 Ethernet 10 BaseT Channels |
| |
| On power-up the processor jumps to the address of 0x02000100 |
| |
| Thus, U-Boot is configured to reside in flash starting at the address of |
| 0x02001000. The environment space is located in NVRAM separately from |
| U-Boot, at the address of 0x03000000. |
