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.
