Hi Paul, very happy to read your reply! I confirm that: 1) grounding pin 42 to go into test mode - OK, all the grounds were connected together: programmer's, mainboard's and KB9012's 42 pin 2) powering the mainboard - OK, but only by power adapter, battery was not plugged in. if I do not connect a power adapter, KB9012 cannot be detected at all, which is expected behavior. Maybe you are connecting the battery while doing this; there should be some reason why your results are different. In any case, this 50% detection issue is just a minor inconvenience at the moment. What surprising me more is that reading time difference between BPv4 and CH341A
I have some questions for you regarding Origami, but since they are not directly related to flashrom I separate them into another private message without CC'ing a list (you will receive it in less than a hour) Best regards, mikeb On Fri, Sep 30, 2016 at 11:20 PM, Paul Kocialkowski <[email protected]> wrote: > Hi, I got your emails just fine, I just didn't have time to sit down and > write a proper reply but I'm very enthusiasic about working with you ! > > Cheers, > Paul Kocialkowski > > Le vendredi 23 septembre 2016 à 03:16 +0300, mikeb mikeb a écrit : > > Good day!
