  1. This document describes the board support for
  2. Dil/NetPC DNP/5370 (http://www.dilnetpc.com/dnp0086.htm) module.
  3. The distributor is SSV (http://www.ssv-embedded.de),
  4. The module used to develop the support files contains:
  5. * Processor: Blackfin BF537 Rev 0.3 (600 MHz core / 120MHz RAM)
  6. * RAM: 32 MB SDRAM
  7. Hynix HY57V561620FTP-H 810EA
  8. Connected to Blackfin via "Expansion Bus"
  9. Address range 0x0000.0000 - 0x1fff.ffff
  10. * NOR flash: 32 MBit (4 MByte)
  11. Exel Semiconductor ES29LVS320EB
  12. Connected to Blackfin via "Expansion Bus",
  13. Chip Selects 0, 1 and 2, each is connected
  14. to a 1 MB memory bank at Blackfin, therefore
  15. only 3 MB accessible.
  16. Address range 0x2000.0000 - 0x202f.ffff
  17. CFI compatible
  18. Exel Semiconductor was bought by Rohm Semiconductor (www.rohm.com).
  19. * NAND flash: 64 MBit (8 MByte)
  20. Atmel 45DB642D-CNU
  21. Connected to Blackfin via SPI
  22. CFI compatible
  23. * Davicom DM9161EP Ethernet PHY
  24. * A SD card reader, connected via SPI
  25. * Hardware watchdog MAX823 or TPS3823
  26. (other devices not listed here)
  27. To run it, the module must be inserted in a 64 pin DIL socket
  28. on another board, e.g. DNP/EVA13 (together: SSV SK28).
  29. The Blackfin is booted from NOR flash. The NOR flash data begins
  30. with the U-Boot code and is then followed by the Linux code.
  31. Finally, the MAC is stored in the last sector.
  32. You may need to adjust these settings to your needs.
  33. The memory map used to develop the board support is:
  34. Memory map:
  35. 0x00000000 .. 0x01ffffff SDRAM
  36. 0x20000000 .. 0x202fffff NOR flash
  37. RAM use:
  38. 0x01f9bffc .. 0x01fbbffb U-Boot stack
  39. 0x01f9c000 .. 0x01f9ffff U-Boot global data
  40. 0x01fa0000 .. 0x01fbffff U-Boot malloc() RAM
  41. 0x01fc0000 .. 0x01ffffff U-Boot execution RAM
  42. NOR flash use:
  43. 0x20000000 .. 0x0002ffff U-Boot
  44. 0x20004000 .. 0x20005fff U-Boot environment
  45. 0x20030000 .. 0x202effff Linux kernel image
  46. 0x202f0000 .. 0x202fffff MAC address sector
  47. NOR flash is 0x00300000 (3145728) bytes large (3 MB).
  48. Max space for compressed kernel in flash is 0x002c0000 (2883584) bytes (2.75 MB)
  49. Max space for u-boot in flash is 0x00030000 (196608) bytes (192 KB)
  50. The module is hardwired to BYPASS boot mode.
