| bunnie | <CarlFK "that was 2 years ago - is it sti"> I think they have finally absorbed the patch to deal with the drive strength issue on the drivers | 12:24 |
| bunnie | however, I have not tried a mainline openocd on the boards yet. what you'll see is when you go to do a firmware update, it'll stall because you get random bit corruption due to the signal integrity being terrible from the drive strength being wrong | 12:25 |
| bunnie | the patch I had tunes that. ideally, this would be the sort of thing you could specify as an argument to openocd but I tried doing a PR to them once and...let's just say it's not a welcoming crowd. | 12:26 |

| CarlFK | http://openocd.zylin.com/#/c/4721/ work around bcm2835 gpio hardware synchronization bug | 19:06 |
| tpb | Title: Gerrit Code Review (at openocd.zylin.com) | 19:06 |
| bunnie | ah right, that reminds me now exactly the issue. It wasn't a drive strength problem, it was a problem with the way the BCM2835 synchronizes reads across clock domains | 19:10 |
| bunnie | you'd lose reads occasionally the way it implemented at the time | 19:10 |
| bunnie | I think this was actually fixed, they eventually took some other approach to creating a read barrier across the clock crossing | 19:11 |
| bunnie | not by my PR but someone else went through the trouble of pushing it | 19:11 |
