| 07:35 | Ke> | topi`: what are the best wireless speeds you have gotten on linux |
| 07:43 | jnettlet[m]> | 500Mbps is stardard for me |
| 07:43 | jnettlet[m]> | that is with 2x2 mimo 802.11AC 5Ghz |
| 07:44 | Ke> | both ap and sta linux? |
| 07:44 | jnettlet[m]> | yes |
| 07:44 | Ke> | nice to hear |
| 07:44 | jnettlet[m]> | for sta, I have my xps 9350 with a killer wifi m.2 card in it |
| 07:45 | Ke> | I haven't particularly optimized, but I have never seen anything above 100Mbps |
| 07:45 | Ke> | I think I have only had 802.11n hw anyway |
| 07:45 | jnettlet[m]> | I have also tested intel's 2x2 802.11ac and it gets more like 500Mbps RX and 300Mbps TX. |
| 07:46 | Ke> | then again I would be more pleased to have nic that had fw security updates |
| 07:47 | jnettlet[m]> | which nic is that? |
| 07:49 | Ke> | I don't think manufacturers care about releasing updates |
| 07:49 | Ke> | broadcom released security updates for apple, but not for linux users |
| 07:50 | jnettlet[m]> | yes I know. Also for Google. |
| 07:50 | jnettlet[m]> | I have opened a support request with Cypress regarding this. |
| 07:51 | Ke> | in general I guess, the fw is probably the same, it would just need to be extracted |
| 07:51 | Ke> | well it varies from chip to chip |
| 07:51 | Ke> | but if you would happen to have one of the chips supported by ios or whatever google devices they support |
| 07:52 | jnettlet[m]> | unfortunately it isn't. the RPi firmware is newer so can't be used. the iPhone 4/4s uses the bcm4330 but I am not sure if they received the fix. |
| 07:54 | jnettlet[m]> | and google only fixed the bcm4343 firmware. https://android.googlesource.com/platform/hardware/broadcom/wlan/+/770dbc7d216289c0b93630899edd2f52aad780a5 |
| 16:10 | dgilmore> | hey all. has anyone seen the hummingboard-edge with an imx6 solo fail to load u-boot.img |
| 16:11 | rabeeh> | dgilmore: have a console dump? |
| 16:14 | dgilmore> | rabeeh: SPL: Unsupported Boot Device! |
| 16:14 | dgilmore> | SPL: failed to boot from all boot devices |
| 16:15 | rabeeh> | which rev of HummingBoard you have? |
| 16:15 | rabeeh> | 1.2 or 1.4? |
| 16:15 | dgilmore> | I am using the upstream u-boot as I can not build the solid run u-boot |
| 16:15 | dgilmore> | 1.2 |
| 16:15 | rabeeh> | hmm |
| 16:15 | dgilmore> | rabeeh: got it |
| 16:15 | rabeeh> | did you try the SR u-boot? |
| 16:16 | dgilmore> | had to add a jumper on pin 7 and 8 |
| 16:16 | rabeeh> | ? |
| 16:16 | rabeeh> | why? |
| 16:16 | rabeeh> | the 2x4 boot header? |
| 16:16 | rabeeh> | this is not functional on HB2 rev 1.2 |
| 16:16 | dgilmore> | I do not know why |
| 16:17 | dgilmore> | I added the jumper and SPL was able to laod u-boot |
| 16:17 | dgilmore> | rabeeh: https://paste.fedoraproject.org/paste/VPxGDC7n50qZqu~0TKHjzw |
| 16:17 | dgilmore> | first was without the jumper |
| 16:17 | dgilmore> | second was with |
| 16:18 | dgilmore> | I guess SPL is looking for it |
| 16:19 | rabeeh> | my guess is that your SOM efuses are not set to boot from the micro SD |
| 16:19 | dgilmore> | possibly |
| 16:20 | dgilmore> | I ordered the board in June 2016, but this is the first I have really sat down to try make it work |
| 16:20 | rabeeh> | oh; fedora 25 |
| 16:21 | rabeeh> | are you using the one that already has 50+ device trees? |
| 16:21 | rabeeh> | --> /dtb-4.8.4-301.fc25.armv7hl/imx6dl-cubox-i.dtb |
| 16:21 | dgilmore> | I am using the stock standard fedora images |
| 16:22 | dgilmore> | entirely upstream bits |
| 16:22 | rabeeh> | great !! |
| 16:22 | dgilmore> | not sure that is the right dtb though |
| 16:22 | rabeeh> | it is not |
| 16:22 | dgilmore> | ass I am not getting any kernel output |
| 16:22 | dgilmore> | as |
| 16:23 | rabeeh> | should be imx6dl-hummingboard2.dtb |
| 16:23 | rabeeh> | this is probably because u-boot didn't detect HB2 correctly |
| 16:24 | dgilmore> | likely |
| 16:25 | dgilmore> | rabeeh: cheers booting now |
| 16:26 | dgilmore> | will work on some patches to u-boot |
| 16:26 | dgilmore> | having only gcc7 available makes the solidrun sources not very useful |
| 17:35 | dgilmore> | rabeeh: you should see an email from me soon |
| 17:41 | jnettlet[m]> | dgilmore: I have u-boot patches for mainline, that allow fedora 26 to boot with no configuration. |
| 17:42 | jnettlet[m]> | although I am still working on getting overlay support for everything working. Since your board is so old that won't effect you. |
| 17:43 | dgilmore> | jnettlet[m]: it works just fine with no configuration |
| 17:44 | dgilmore> | upstream u-boot currently has no logic to detedt the hummingboard2 |
| 17:44 | jnettlet[m]> | dgilmore: for sdhc yes, but not for other boot methods, and not with overlay support. |
| 17:44 | jnettlet[m]> | yes I know |
| 17:44 | jnettlet[m]> | or handle 4GB soms. |
| 17:44 | dgilmore> | jnettlet[m]: okay |
| 17:45 | dgilmore> | apparently the hummingboard-edge changes mac every boot |
| 17:46 | dgilmore> | [ 13.071542] fec 2188000.ethernet (unnamed net_device) (uninitialized): Invalid MAC address: 00:00:00:00:00:00 |
| 17:46 | dgilmore> | [ 13.081586] fec 2188000.ethernet (unnamed net_device) (uninitialized): Using random MAC address: a2:16:b0:1f:ed:00 |
| 17:46 | jnettlet[m]> | your som is unfused |
| 17:46 | jnettlet[m]> | you can use the fuse command in u-boot to set it to whatever you would like. |
| 17:50 | dgilmore> | nice |
| 18:06 | dgilmore> | jnettlet[m]: is there a doc somewhere that lays out what banks and words to program? |
| 18:07 | jnettlet[m]> | dgilmore: https://wiki.solid-run.com/doku.php?id=products:imx6:microsom:imx6-fuse-developers&s[]=fuse |
| 18:07 | jnettlet[m]> | got down to the MAC address section in u-boot |
| 18:46 | dgilmore> | jnettlet[m]: there is no MAC address section in u-boot |
| 18:46 | dgilmore> | the mac address section only has |
| 18:46 | dgilmore> | echo 0xd063 > /sys/fsl_otp/HW_OCOTP_MAC1 |
| 18:46 | dgilmore> | echo 0x12345678 > /sys/fsl_otp/HW_OCOTP_MAC0 |
| 18:47 | dgilmore> | the only u-boot section is to boot from microsd |
| 18:48 | jnettlet[m]> | wonderful. |
| 18:48 | jnettlet[m]> | fuse prog 4 3 is the upper bits |
| 18:48 | jnettlet[m]> | fuse prog 4 2 is the lower bits |
| 18:48 | dgilmore> | okay thanks |
| 18:53 | dgilmore> | jnettlet[m]: done thanks |
| 23:14 | jnettlet[m]> | For anyone interested here is a mainline branch for the clearfog a38x. https://github.com/SolidRun/u-boot/tree/master-a38x |
| 23:16 | jnettlet[m]> | it adds fun things like working support for usb, sata, spi-nor, rtc. |
| 23:16 | rabeeh> | \o/ |
| 23:16 | jnettlet[m]> | to come soon are a proper comphy driver so you can configure the mini-pcie ports on demand |
| 23:16 | jnettlet[m]> | will start pushing to mainline this weekend |
| 23:17 | jnettlet[m]> | and it supports the distro boot. So grab Fedora 26 image an SDHC write u-boot, and boot right up. |
