| 07:44 | wumpus | "ultra low power always on audio processing" ahh, that :-) |
| 07:45 | wumpus | GC7000Lite isn't familiar to me, we'll see |
| 07:54 | jnettlet | wumpus, looks like their next-gen chips |
| 08:23 | topi` | hopefully with vulkan support |
| 08:25 | jnettlet | they claim vulkan support |
| 08:26 | topi` | it seems we need an EMC shielding for the HB2... to pass some EMC tests. Any ideas whether there are somewhere vendors which create EMC shieldings? I know they exist since many products have small emc cages |
| 08:28 | jnettlet | topi`, for which parts? |
| 08:32 | topi` | jnettlet: I don't know. My colleague says that it might not pass the EMC tests, so it needs a metal case |
| 08:33 | topi` | but the metal case won't fit into the small space available |
| 08:33 | topi` | so I was thinking of a EMC cage |
| 08:33 | jnettlet | topi`, we have passed EMC testing in Israel and specifications for the EU |
| 08:48 | topi` | the Certificate of Compliance doc states: EN 55024: 2010, 55022:2010:2011, AS/NZS CISPR 22: 2009+A1:2010 |
| 08:48 | topi` | are these compliances with or without the Alu Case? |
| 09:00 | jnettlet | those are without |
| 09:11 | SYS64738 | hi |
| 09:35 | topi` | btw I'm moving the rootfs from jessie to stretch |
| 09:35 | topi` | stretch has entered feature freeze and I need newer libdrm :) |
| 09:59 | topi` | it seems that some guy at pengutronix.de is working on etnaviv DRM |
| 09:59 | topi` | I wonder if he's paid or just a hobbyist .) |
| 10:10 | jnettlet | topi`, yes there are people working on it. However nouveau had up to 5 paid developers working on it fulltime and it still took about 5 years to get something usable. |
| 10:11 | topi` | NVIDIA wasn't very helpful... |
| 10:21 | jnettlet | and Vivante is less helpful |
| 11:04 | topi` | is the i2eX SOM with 4GB or 8GB emmc? |
| 11:08 | malte__ | 8 |
| 11:10 | topi` | great |
| 11:10 | topi` | don't have to shoehorn a distro into such a cramped space :) |
| 13:38 | topi` | if we need to change the antenna from the "small" version on the HB2 into a "normal" antenna which goes outside of the box, how can the antenna be detached? is it necessary to take out the entire SOM to access the antenna? |
| 13:39 | topi` | I have the older SOMs and it seems the antenna goes under the big heatsink |
| 13:39 | topi` | what is the type of the antenna connector? |
| 13:41 | jnettlet | topi`, it is a standard hirose u.fl connector |
| 13:42 | jnettlet | same as pretty much all mini pcie wifi cards |
| 13:49 | topi` | I ran into trouble wit the old uboot 2013.10 and my newfangled Debian Stretch rootfs |
| 13:50 | topi` | it seems that debian defaults to mkfs'ing with the new option metadata_csum which is incompatible with e.g. 3.4 kernels |
| 13:50 | topi` | 3.14 does support it |
| 13:51 | topi` | unfortunately, neither does UBOOT understand it. So when I tried to boot with my stuff in /boot, it refused to read /boot/zImage |
| 13:53 | topi` | jnettlet: is there anywhere a document about the process of fusing the SOM to boot from emmc? |
| 13:53 | topi` | we cannot ship products with SD cards, so everything has to work from emmc |
| 13:59 | jnettlet | topi`, yes wiki.solid-run.com |
| 14:00 | topi` | we ordered the stuff unfused, if it is unfused, then from where does it boot? |
| 14:02 | topi` | ok, so it seems you can do the fuses from a buildroot'ed disk that can be uploaded via a linux pC? |
| 14:02 | topi` | I'm happy with that, I was afraid for some windows software. I just gave away my corporate windows machine for a macbook pro :) |
| 14:07 | jnettlet | topi`, you need to make a usb-a male to usb-a male cable with a resistor on VCC and boot it over usb-otg |
| 14:07 | topi` | yes, we'll take care of that |
| 14:08 | topi` | we probably need to "flash" the eMMC contents at the same moment, before fusing |
| 14:08 | topi` | if something goes wrong, is there a way to "unbrick" a device? |
| 14:09 | topi` | but basically if it can boot to UBOOT, then we already have all the necessary sw to boot from e.g. SDcard |
| 15:40 | topi` | UBOOT is behaving realy odd here |
| 15:40 | topi` | usually, uboot's console is pretty fast and if I try printenv, it scrolls out faster than I can read |
| 15:40 | topi` | now it prints like 2-3 lines per second, what's going on? |
| 15:40 | topi` | also does not recognise my mmc :( |
| 15:41 | topi` | odd, second printenv was really fast |
| 15:41 | topi` | wtf |
| 15:41 | topi` | ext4ls mmc 0 boot return nothing. nada. |
| 15:41 | topi` | the directories are there but they're all empty |
| 15:43 | topi` | I can load a file,that sits in the root dir, though. |
| 15:44 | topi` | I'll try another HB. |
| 15:45 | topi` | it seems ext4ls no longer works with this ext4 filesystem created by recent tools |
| 15:46 | topi` | what can I do? |
| 15:47 | topi` | I mount it on another box and everything is there |
| 15:47 | topi` | maybe I'll just have a small vfat partition in the beginning for uboot to do its stuff |
| 15:54 | topi` | the sad thing about vfat is that there are no symlinks... |
| 16:03 | topi` | maybe uboot could work with ext2... |
| 16:08 | jnettlet | topi` just remove those options from the extra filesystem |
| 16:08 | jnettlet | ext4 filesystem |
| 16:11 | topi` | I don't know for sure which options are those responsible for the misbehavior |
| 16:12 | topi` | I already created the ext4 without that damn metadata_csum, but it didn't seem to help |
| 16:12 | topi` | time is of essence, thus vfat |
| 16:12 | topi` | I still have to figure out how to flash the whole thing into the target eMMCs via that USB-OTG loader... |
| 16:13 | topi` | well not today, the boards won't ship until next week for sure |
| 16:13 | topi` | is there a reason you're still using an uboot from 2013? |
| 16:13 | topi` | just curious... |
| 16:47 | vpeter | topi`: There is one file in /etc which has some defaults about filesystems. Let me find it. |
| 16:48 | vpeter | and you can change options with tune2fs. |
| 16:49 | vpeter | file is /etc/mke2fs.conf |
| 16:59 | ngochai | How do I make uboot detect usb thumb drive connected to USB connector on my Hummingboard pro? |
| 21:11 | topi` | not sure whether uboot support usb drives... |
| 21:11 | topi` | it does support usb keyboards, though :) |
| 21:24 | ngochai | topi`, uboot can detect my usb drive if I connect it to the USB pin header, but not when connected to the USB connector |
| 22:15 | topi` | they are two different usb controllers, that's why |
