| This document describes the board support for |
| Dil/NetPC DNP/5370 (http://www.dilnetpc.com/dnp0086.htm) module. |
| The distributor is SSV (http://www.ssv-embedded.de), |
| |
| The module used to develop the support files contains: |
| |
| * Processor: Blackfin BF537 Rev 0.3 (600 MHz core / 120MHz RAM) |
| |
| * RAM: 32 MB SDRAM |
| Hynix HY57V561620FTP-H 810EA |
| Connected to Blackfin via "Expansion Bus" |
| Address range 0x0000.0000 - 0x1fff.ffff |
| |
| * NOR flash: 32 MBit (4 MByte) |
| Exel Semiconductor ES29LVS320EB |
| Connected to Blackfin via "Expansion Bus", |
| Chip Selects 0, 1 and 2, each is connected |
| to a 1 MB memory bank at Blackfin, therefore |
| only 3 MB accessible. |
| Address range 0x2000.0000 - 0x202f.ffff |
| CFI compatible |
| |
| Exel Semiconductor was bought by Rohm Semiconductor (www.rohm.com). |
| |
| * NAND flash: 64 MBit (8 MByte) |
| Atmel 45DB642D-CNU |
| Connected to Blackfin via SPI |
| CFI compatible |
| |
| * Davicom DM9161EP Ethernet PHY |
| |
| * A SD card reader, connected via SPI |
| |
| * Hardware watchdog MAX823 or TPS3823 |
| |
| (other devices not listed here) |
| |
| To run it, the module must be inserted in a 64 pin DIL socket |
| on another board, e.g. DNP/EVA13 (together: SSV SK28). |
| |
| The Blackfin is booted from NOR flash. The NOR flash data begins |
| with the U-Boot code and is then followed by the Linux code. |
| Finally, the MAC is stored in the last sector. |
| You may need to adjust these settings to your needs. |
| The memory map used to develop the board support is: |
| |
| Memory map: |
| 0x00000000 .. 0x01ffffff SDRAM |
| 0x20000000 .. 0x202fffff NOR flash |
| |
| RAM use: |
| 0x01f9bffc .. 0x01fbbffb U-Boot stack |
| 0x01f9c000 .. 0x01f9ffff U-Boot global data |
| 0x01fa0000 .. 0x01fbffff U-Boot malloc() RAM |
| 0x01fc0000 .. 0x01ffffff U-Boot execution RAM |
| |
| NOR flash use: |
| 0x20000000 .. 0x0002ffff U-Boot |
| 0x20004000 .. 0x20005fff U-Boot environment |
| 0x20030000 .. 0x202effff Linux kernel image |
| 0x202f0000 .. 0x202fffff MAC address sector |
| |
| NOR flash is 0x00300000 (3145728) bytes large (3 MB). |
| Max space for compressed kernel in flash is 0x002c0000 (2883584) bytes (2.75 MB) |
| Max space for u-boot in flash is 0x00030000 (196608) bytes (192 KB) |
| |
| The module is hardwired to BYPASS boot mode. |
