sure I will report :)

for now, I don't have the device appearing in /dev/

probably bad wiring right ? I don't have any soft or lib to install on raspbian to have it recognized ? (flashrom runs fine)

also, my raspi-blacklist.conf is empty (rpi3b with latest raspbian). and the modprobe commands doesn't work

edit:
found my answer. SPI have to be enabled manually via raspi-config command

https://www.raspberrypi.org/documentatio...i/spi/README.md

but still not working, despit modprobe spi-bcm2835 (this changed also) chip is not detected :'( any idea ?

I did wiring again, same problem. I think the wiring on my jspi1 is different.

I could find some pics on russia/chinese forums...

I'm totally lost now... should I put gnd on 9 ? is CS on 9 ? should I gnd 11 or 12 ? :/

probably this is the issue, especially that I have MSI Z97 1150...

not sure I understood the solution but it's about variation of tension from 3.3 to 3.6 to enable which seems too complicated...

I usually have multimeter yes, but I'm not home right now. I'm on the way to get an old one from friend, not sure it works good tho, but I should be able to test continuity.

I compiled the flashrom myself. I don't know if it is compiled with linux_spi support ? How do I know ? I enabled SPI after compiling it.

What do you think about the wiring shown on russian forum, with 12 pin, a transistor linked to CS pin and gnd ? is there a way to bypass transistor or keep it open ? (i did some electronic studies but it's faaarrr ahah...)

which pinout on link 2?

so, just connecting CS on 11 instead of 5 ?

Hi Pacman!


I am now back home and was able to do testing with a proper multimeter.

So I am exactly in this situation for all pins except 9:


I have a transistor next to JSPI1 and bios, but it does not make contact between 5, 9 from JSPI1 to any of the transistor pin.
Maybe it's not this one, but it's the only one around.

So, i'm thinking of asking a friend (without parkinson's disease) to old one multimeter pin on CS pin directly on bios, and link it to my raspberry while flashing. that should be doable.

And I will connect 11/12 to VCC.
