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. |
