My build is finally nearing completion...still some tidying up to do.
Next the software side of things...🙂

Curious: Why didn't you just use the breadboard area on the Hermes-BBB?

ichiban · 2015-05-05 8:36 pm

Ok, so I'm giving V4 flash a try again,
supposed to use /opt/scripts/tools/eMMC/generic-eMMC-flasher-12mb.sh

but, when I do a ls -l it's not there!?

miero · 2015-05-05 9:36 pm

bern: it seems that the source package was not properly cleaned before packaging. please try following:

Code:

cd /usr/src/linux-headers-4.0.0-botic5
rm -f ./scripts/genksyms/genksyms ./scripts/selinux/genheaders/genheaders ./scripts/selinux/mdp/mdp ./scripts/kallsyms ./scripts/sortextable ./scripts/mod/mk_elfconfig ./scripts/mod/modpost ./scripts/kconfig/mconf ./scripts/kconfig/conf ./scripts/unifdef ./scripts/dtc/dtc ./scripts/conmakehash
make -k scripts
# some errors will be printed by previous command, ignore them

Then you can build mt7601u without errors 🙂

Code:

cd mt7601u
make -C /lib/modules/`uname -r`/build M=$PWD
make -C /lib/modules/`uname -r`/build M=$PWD modules_install

miero · 2015-05-05 9:58 pm

bern: oops, but the module will not load because of missing symbols ieee80211_*

I think I will need to rebuild kernel with other options for this...

miero · 2015-05-05 10:23 pm

bern: after loading mac80211 module, the mt7601u can be loaded too... but it immediately crashes system with oops. I've already reported this to author.

Duffy Moon · 2015-05-06 12:22 am

miero, are there currently any wifi dongles which can be used without modifying Botic? If not, do you plan to integrate wifi drivers into Botic?

miero · 2015-05-06 6:05 am

There are standard wifi drivers compiled in the Botic kernel. For example the USB Wifi Edimax EW-7711UMn works, but it is much slower than Ethernet.

Check this site for more compatible devices: RPi USB Wi-Fi Adapters - eLinux.org

Beware of these that are not in the list or requires external drivers!

miero · 2015-05-06 6:17 am

bern: try this... it works for me also with Wifi dongle 🙂

Code:

apt-get install gcc-4.7
cd mt7601u
make -C /lib/modules/`uname -r`/build M=$PWD CC=gcc-4.7
cp mt7601u.ko /lib/modules/$(uname -r)/
depmod -a
modprobe mt7601u

I've opted for stacking, saves a bit of wiring.

Thank you miero🙂
New module build with gcc-4.7 was successful. However I suspect that not all from old/prevoius build was cleared. When I plug usb wifi dongle I see:

Also when i want to see loaded modules and type: lsmod
nothing appears in the putty....
Mayby I need more powerfull power supply for BBB+WIFI dongle? Currently, temporarily I use 1A USB charger...

miero · 2015-05-06 8:10 am

bern: it seems it is not cleared well, you have to execute "make clean" in the mt7601u directory first

It seems like new modules have been loaded but system did not recognize new wifi interface..

miero · 2015-05-06 10:14 am

And now it is possible that you do not have enough power for this. You can check last lines of dmesg command for some USB errors.

Miero should I do something with /lib/firmware/mt7601u.bin (move to other directory or something) :scratch1:

yes, there were instructions on driver page you should follow... 🙂

Code:

wget https://github.com/porjo/mt7601/raw/master/src/mcu/bin/MT7601.bin
mv MT7601.bin /lib/firmware/mt7601u.bin

Yep. I downloaded improper firmware (vendor instead of modified) version.
After firmware replacement wlan0 interface is available 😎
So far so good.

I've had no luck with miero's remote storage settings in /etc/fstab. Manual mounting with the command

mount -t cifs //<MachineName>/<SharedFolder> /data/remote -o username=<DomainName>/<username>,password=<password>

works, but saving that in /etc/fstab doesn't.

Commands to be executed at the boot can be written into file /etc/rc.local

After activation hostname DHCP in the wicd-curses for the short time I saw list of wifi networks (including mine). I guess I could not connect for longer because I lost connection due to insufficient current. Driver will be probably working when I replace PSU from 1A to 2A.
But what to do to load mac80211 and mt7601u modules automatically/dynamically?

miero · 2015-05-06 9:43 pm

Duffy Moon: the /etc/fstab uses different format, check the example on http://bbb.ieero.com/

bern: It should be enough to write line with "mt7601u" into /etc/modules
