[flashrom] ENE KB9012 patches: new test results

Sat Oct 1 04:18:24 CEST 2016

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
