Help programming IT8987 with vertyanov

[myth77]

The motherboard is HP Omen 17 G38D, ITE8987, i am getting error message that "motherboard not powered up?
i use this settings:
Quanta G38D KB_pins=32 LEFT DOWN 1MM PD0=26 PD1=22 PD2=20 PD3=15 PD4=19 PD5=23 PD6=16 PD7=18 BUSY=29 STB=21 AFD=32 INIT=25 SLIN=24 KSI4=28 KSI5=27

The board is not starting automaticly when i plug in adapter. When charger/adapter is plugged i have +3VPCU, +3VECACC and +3V_VSTBY, they are all around 3,3 V. I dont have on pin 11 +3v but i used lab power supply and injected 3.2V....and then tried to read.... but again i get error "motherboard not powered up?"


what am i missing? Any help appreciated.

1st pin location ok? Also check pin connections from programmer to mainboard, sometimes the flex cable has bad connections. GND connected?

yes, everything is properly connected...i checked several times with multimeter connections from programmer to mainboard. Gnd connected.
Also i used programmer on several other motherboards with success so the only problem is this one.
And the motherboard is fine..its working and i am trying to extract ITE from it to use it on some other motherboard but always message "not powered up"...
I didnt used programmer till now with IT8987, maybe there are some differences there...

Sadly can not help you there, i have used the programmer on G35D, ITE8987 and i did get a read and write there. Can not remember details - but read on programmer ver 2 and ITE8987 should be possible.
A few times i have had connection only when mainboard is powered on - not just connected to power adapter.
I see that Vertyanov has not answered to your post at ascnb1 also...

go to ascnb1.ru forum and ask Vertyanov directly?
