  1. Intel Platform-CalpellaIntroduction Chini Yang 21 .Sep. 2010

  2. Agenda • Calpella Platform Block Diagram. • CPU(Clarksfield/Arrandale) & PCH(Ibex Peak-M) & EC(IT8570E) Features Introduce Briefly. • N71Ja Power On Sequence Illuminate for Detail. • Common Bugs Analyze on N71Ja/Jq. • Q & A.

  3. CalpellaPlatform • Calpella vs. Montevina

  4. Calpella Platform

  5. Calpella Platform

  6. Calpella-N71Ja Block Diagram

  7. Calpella CPU • Clarksfield(C) vs. Arrandale(A)

  8. Calpella CPU

  9. Calpella PCH

  10. Calpella CLK

  11. An Important Component Platform Needed - EC • Keyboard matrix/Touchpad control • Power/Charger… etc, LEDs instruct • Fan tachometer control • Power management (sleep/hibernate/wake up/Lid switch) • Power sequence control with PCH • Battery charger/Cell capacity/Temperature monitor • GPIO control PS: If the system cannot power on, we can snatch LPC_FRAME# to make known that whether EC has worked.

  12. Power Sequence Provision - ACPI Power State • G0/S0:Full on • G1/S1:CPU sleep ----PCH has the option toassert the CPUSLP# signal to further reduce processor power consumption. • G1/S3:Suspend to RAM ----The system context is maintained in system DRAM,but power is shut off tonon-critical circuits. Memory is retained, and refreshescontinue. All clocks stop except RTC clock. • G1/S4:Suspend to Disk ----The context of the systemismaintained on the disk. Allpower is then shut off to the system except for the logic required to resume. • G2/S5:Soft off ----System context is not maintained. All power is shut off exceptfor the logic required to restart. Afull boot is required when waking. • G3:Mechanical off ----Power failure Because the system does not have any power.

  13. Power Sequence Types on Notebook • Five types of power sequence • G3S5 • S5S0 (Power on) • S0S5 (Power down) • S3S0 • S0S3

  14. Power on---AC/DC Block Flow • Difference: • AC mode (plug in adaptor): G3S4/S5 , • have VSUS power. (to save power) • DC mode (only plug in battery): G3S4/S5 , • have no VSUS power.

  15. Power on---AC Sequence CPU 2.A/D_DOCK_IN MB39A132 18.H_CPUPWRGD 19.PLT_RST# 20.H_CPU_RST# 4.+3VA 3.AC_BAT_SYS PCH RT8206AGQW 16.VRM_PWRGD 5.VSUS_ON RTC BAT 6.+3VSUS/+5VSUS 1.RTCRST# 17.PM_PWROK 12.PM_SUSB# 11.PM_SUSC# 8.PM_RSMRST# 10.PWRBTN# 9.PWR_SW# EC ITE8570 7.VSUS_GD 4.AC_OK=1 13.SUSC_ON MEMORY POWER(+1.8V,0.9V) 14.SUSB_ON OTHER MAIN POWER(+1.5V,+1.05V etc.) Vcore Controller 16.VRM_PWRGD 15.CPU_VRON (110ms)

  16. Power on---DC Sequence CPU 2.BAT_CON MB39A132 18.H_CPUPWRGD 19.PLT_RST# 20.H_CPU_RST# 4.+3VA 3.AC_BAT_SYS PCH RT8206AGQW 16.VRM_PWRGD 6.VSUS_ON RTC BAT 7.+3VSUS/+5VSUS 1.RTCRST# 17.PM_PWROK 12.PM_SUSB# 11.PM_SUSC# 9.PM_RSMRST# 10.PWRBTN# 5.PWR_SW# EC ITE8570 8.VSUS_GD 4.AC_OK=1 13.SUSC_ON MEMORY POWER(+1.8V,0.9V) 14.SUSB_ON OTHER MAIN POWER(+1.5V,+1.05V etc.) Vcore Controller 16.VRM_PWRGD 15.CPU_VRON (110ms)

  17. N71Ja Power on Sequence(1)

  18. N71Ja Power on Sequence(2)

  19. N71Ja Power on Sequence(3)

  20. N71Ja Power on Sequence(4)

  21. N71Ja Power on Sequence(5)

  22. Power Down---General Sequence

  23. Power Down---General Sequence • Power down---General Sequence

  24. Common Bugs • 1.The system can not be powered on, and the adaptor LED indication flicker. Here is somewhere short, check all power rails whether have been short to GND. • 2.The system can not be powered on, and power LED not lighten. Maybe The BIOS ROM content has been wrecked. +3VA powered? Why not VSUS power? Power IC or MOSFET or Diode burnout? • 3.The power LED lighten, but the system can not bring up to DOS. plug in debug card, view the 80 post code, for example: 80 code no motion, show 00 –> CPU not work –>measure power sequence black screen, show d0~d5 –> memory plug failed or memory broken black screen, show F0~F2 –> one DIMM slot failed show 38 –> check USB port and USB device If not mount LPC debug & New card debug card because of cost down, try to flash BIOS by JIG board or measure sequence. • 4.The system often show blue screen suddenly in OS un-install drives (even enter safe mode), find whether a device driver installed wrongly cause it un-plug device to check BIOS updated? Care for BIOS release note check FAN status/thermal module –> over temperature? and so on……

  25. RMATraining Request • How to judging the CPU’s function when it on board? • Debug Card -> Reset -> Power, CLK ->Visual Inspection (Impurities, PIN Broken, curving, Error Component ) • Do not boot up, How to do? • Check Debug code • Debug code:00 -> Reset , Power, CLK , Visual Inspection. • Debug code: OK -> GPU, CRT/LVDS • The Voltage and CLK is OK, but no display. How to do? • Remove all Device, Check DIMM, Flash EEPROM, Reset COMST, Check all reset nets, Check Debug code. • Blue screen, Hung up, How to do? • Remove all Device, Check DIMM, Flash EEPROM, Change HDD , Check FAN & Thermal Module, Check Windows error code. • The Difference with EC ChipITE8510、8511、8752 、8512 、8502 、8570. • ITE8510、8511 -> SantaRosa platform -> ISA ROM • ITE8752、8512 -> Montevina platform -> SPI ROM • ITE8570 -> Calpella platform -> SPI ROM

  26. THE END THANKS
