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.
