Has anyone in this thread experienced not being able to read the TB3 flashrom chip?
I can't get past:
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.
I'm not having luck flashing the chip.
I've followed all the guides/mini guides for the flashing procedure. Even tried two different CH341A usb programmers - low voltage 3.3v and the original 5v version (tested with multimeter and only 3.3v for pins 4 and 8) I've tried eliminating any possible issues. Used different USB ports/extension cables. I've tried both Windows ASprogrammer, CH341A miniprogammer (both can see CH341A device/driver, but read out is "unknown"), and flashrom via home-brew in terminal gives the No EEPROM/flash device found.
From everything I read it has to do with a bad connection to the chip and clip. I've swapped the the different clips from both usb programmers and still same result.
When I attach the thunderbolt chip and usb programmer the Red LED illuminates on the programmer. When I then plug into the USB port the Red LED becomes brighter.
Is it possible that something is physically wrong with the chip prohibiting me from getting a connection for the programmer to read it? I don't have another TB3 card to test to verify this, but was wondering if anyone else had similar issues.
And lastly, shout out to
@CaseySJ for the thorough guide. you've clearly helped hundreds making a super stable and reliable hackintosh. I used this guide to upgrade my z370 Maximus x code with the Z490 Vision D with i9 10900k and 5700xt. Pretty happy with the results and now have thunderbolt as an interface. Main reason I'd like to flash is for thunderbolt bridge between two hacks.
