[PATCH 1/4] Obtain correct virtual address for 32-bit BARs on PPC
by Timothy Pearson 13 Oct '16

Re: [flashrom] ENE KB9012 patches: new test results

Hi, I think I may have an explanation for this behavior. Since EDI is enabled via clock detection, it is possible that the first request cannot be served (as it is received concurrently with clock detection) and so gets lost. I have added a dummy read before any required transaction, so that the chip can detect EDI and enable it priori to serving any useful request. This change is available on my git repository[0]. Feel free to try and it and report back, so that I can decide whether to send it to upstream flashrom.

To figure that out, I could give you the spare board that I put out to first write flashrom support while traveling. I know for sure that it works 100% of the time with my setup. > There are four main types of G505S motherboards that I am > aware of: > *) LA-A091P rev.1.0 - discrete graphics is 8570M <-- my case > *) LA-A091P rev.1.A - discrete graphics is 8570M > *) LA-A091P rev.1.A - discrete graphics is R5 M230 > *) LA-A092P rev.1.A - no discrete graphics <-- your case The one I have is marked with LA-A091P rev: 1.A, which has discrete graphics too. I'll order more boards (more or less) soon as I need them for development (both EC and Coreboot), so hopefully I'll get one that has a similar bug. > Also it could be that there was a group of KB9012 with buggy EDI > interface, and both me and Joerg got one :P (but that is less likely) Indeed, but could be possible. I think the best way to figure it out is that I send you one that is known to work reliably with my setup and see if the issue still occurs. > In any case this detection problem is minor, it takes just a couple of > seconds to retry the last console command... Yes indeed, but I'd like to know why it's happening at all. Also, perhaps we can do something about it in the code (IIRC Joerg had sent a change in that direction). I'd be happier if flashrom support for it was reliable for all users :) > On Fri, Oct 7, 2016 at 11:08 AM, Paul Kocialkowski <contact(a)paulk.fr> wrote: > > > > Hi, > > > > Le samedi 01 octobre 2016 à 05:18 +0300, mikeb mikeb a écrit : > > > > > > Hi Paul, very happy to read your reply!

Re: [flashrom] ENE KB9012 patches: new test results

Hi, Le samedi 01 octobre 2016 à 05:18 +0300, mikeb mikeb a écrit : > 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 Sounds good then! Note that the proprietary firmware explicitly disables EDI (the protocol used to access the memory), so grounding pin 42 is the only way to access it. > 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.

What surprising me more is that > reading time difference between BPv4 and CH341A I do not have the battery plugged when flashing the device, and plugging it in doesn't change anything here. How long are your wires? I am using short ones (the likes of 10 cm). For high -speed signals, this can have an influence. Also, you should try to reduce the SPI clock speed: if the "works 1 out of 2 times" issue is caused by a clock speed that is slightly too fast for the KB9012, lowering it could bring the required stability. However, it worked directly with CH341A here. The different read times are likely due to different SPI clock frequencies. I don't know what CH341A uses but it seems to be a good compromise. FTDI programmers tend to use a clock frequency that is too fast for the KB9012, so it has to be divided with divisor=8. However, this makes the read slower than 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) Indeed, let's keep this discussion about flashrom-related topics only. Origami-EC will get its own infrastructure eventually anyway (I hope soon).
