| 16:55 | ngochai | Hi, I have a hummingboard SOM with wifi, which module should be loaded for the wifi interface to show up? |
| 16:55 | cbxbiker61 | brcmfmac |
| 16:58 | ngochai | cbxbiker61, I loaded that but ifconfig only shows eth0 and lo |
| 16:59 | ngochai | dmesg show this: brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50 |
| 17:00 | cbxbiker61 | brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: Oct 25 2011 19:34:12 version 5.90.125.104 |
| 17:01 | cbxbiker61 | make sure you have appropriate firmware installed |
| 17:02 | Gluino | yep you need to install linux-firmware |
| 17:02 | ngochai | where do I get the firmware? |
| 17:02 | Gluino | it's on you package manager |
| 17:03 | Gluino | for debian like i think it's "apt-get install firmware-linux" |
| 17:06 | ngochai | I install linux-firmware and rmod and modprobe brcmfmac again, still not showing up |
| 17:07 | Gluino | what's your distro ? |
| 17:07 | ngochai | ubuntu |
| 17:08 | ngochai | I'm using aizu's kernel though |
| 17:08 | cbxbiker61 | try the xilka kernel, it works |
| 17:08 | ngochai | https://github.com/n-aizu/linux-linaro-stable-mx6 |
| 17:09 | Gluino | my problem was the missing .txt file with the firmware |
| 17:09 | Gluino | it was not included in linux-firmware package |
| 17:09 | Gluino | so i downloaded it separatly |
| 17:10 | ngochai | this file: brcmfmac-sdio.txt? |
| 17:10 | Gluino | the file is : /lib/firmware/brcm/brcmfmac4330-sdio.txt |
| 17:10 | Gluino | yep |
| 17:26 | ngochai | ok got it working, it's the txt |
| 17:26 | ngochai | thank you guys |
| 19:25 | ngochai | when I connect a USB device (which has a USB Y cable connected to powered USB hub) to the hummingboard, the board is powered by the USB port so even if I unplug the micro USB power cable, the board is still running, is this intended? or it's a hardware problem? |
| 19:31 | jnettlet | ngochai, a side effect of the power circuit. It is normal. |
| 19:33 | jnettlet | the 5volt circuit is very simple, and the SOC doesn't need a lot of power to keep running, so the back feed from a USB hub is generally enough to keep the 3.3v rail powered |
| 19:38 | ngochai | jnettlet, it confused me when I unplug the main micro USB power cable |
| 19:39 | jnettlet | :) it is the ghost in the machine |
| 19:39 | ngochai | :) |
| 19:55 | ngochai | jnettlet, does the xilka kernel has the ov5647 camera driver as aizu's one? |
| 19:55 | jnettlet | ngochai, no idea sorry |
| 19:57 | ngochai | the latest official kernel for hummingboard is still here: https://github.com/SolidRun/linux-imx6-3.14 right? |
| 20:07 | jnettlet | yep. a new one is coming very soon |
| 20:11 | ngochai | beside that PiCam ov5647, what camera can be used with the hummingboard MIPI CSI connection? |
