  1. Freescale MPC8610HPCD board
  2. ===========================
  3. Building U-Boot
  4. ---------------
  5. $ make MPC8610HPCD_config
  6. Configuring for MPC8610HPCD board...
  7. $ make
  8. Flashing U-Boot
  9. ---------------
  10. The flash is 128M starting at 0xF800_0000.
  11. The alternate image is at 0xFBF0_0000
  12. The boot image is at 0xFFF0_0000.
  13. To Flash U-Boot into the booting bank:
  14. tftp 1000000 u-boot.bin
  15. protect off all
  16. erase fff00000 +$filesize
  17. cp.b 1000000 fff00000 $filesize
  18. To Flash U-Boot into the alternate bank
  19. tftp 1000000 u-boot.bin
  20. erase fbf00000 +$filesize
  21. cp.b 1000000 fbf00000 $filesize
  22. pixis_reset command
  23. -------------------
  24. A new command, "pixis_reset", is introduced to reset mpc8610hpcd board
  25. using the FPGA sequencer. When the board restarts, it has the option
  26. of using either the current or alternate flash bank as the boot
  27. image, with or without the watchdog timer enabled, and finally with
  28. or without frequency changes.
  29. Usage is;
  30. pixis_reset
  31. pixis_reset altbank
  32. pixis_reset altbank wd
  33. pixis_reset altbank cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio>
  34. pixis_reset cf <SYSCLK freq> <COREPLL ratio> <MPXPLL ratio>
  35. Examples;
  36. /* reset to current bank, like "reset" command */
  37. pixis_reset
  38. /* reset board but use the to alternate flash bank */
  39. pixis_reset altbank
  40. /* reset board, use alternate flash bank with watchdog timer enabled*/
  41. pixis_reset altbank wd
  42. /* reset board to alternate bank with frequency changed.
  43. * 40 is SYSCLK, 2.5 is COREPLL ratio, 10 is MPXPLL ratio
  44. */
  45. pixis-reset altbank cf 40 2.5 10
  46. DIP Switch Settings
  47. -------------------
  48. To manually switch the flash banks using the DIP switch
  49. settings, toggle both SW6:1 and SW6:2.
