VoCore2 Ultimate - is microSD slot working?

Wed Sep 19, 2018 6:29 am

I picked up today my VoCore2 ultimate package.
Played with it and so far so good, works ok, I could cross compile successfully for it, ...
One thing I seem to be having issues with is having it see my extFAT 120GB microSD card.
As far as I can tell I inserted the card correctly in the slot, but nothing shows in the /dev when I do that, can't seem to be detected.

BTW, to insert the card in, I had to enlarge the hole in the case, made it probably 3 times wider than.
What is the deal with that super narrow slot in the case, there is no way in hell anybody can stick a microSD card through it ...

Is there something I need to do and I am not smart enough to figure out?
Is the microSD slot in the VoCore2 Ultimate supposed to be working out of the box?
Or is not yet operational, and that is the reason for the impossibly narrow (i.e. unusable) cut in the case?

Thank you in advance,
R.

Yes, it should be work out of box.
And the hole for TF card should be happen to enough....Should not need tp enlarge.
Are you using correct TF card? Please take a photo.

Once insert, you can find new device at /dev/mmcblk0p1
then call mount /dev/mmcblk0p1 /mnt/mmcblk0p1 you will finish the mount then it should work.
SD card is a strict tested part when out of factory, please let me know the tag number I can check the factory test log. :)

Please see the attached image.
You can also see there the enlarged' CF hole in the case.
The case received had a very narrow cut-out (the CF didn't even fit through the plastic), and that slot was above the internal CF slot anyway
(i.e. even if the CF would have fit through it), it was not aligned with the internal reader)

The CF I used is 120GB one, and last night I reformatted it again as extFAT (just in case), and used it from a different computer just fine.
Then put it in my VoCore2 and as before, 'ls /dev/mmc*' finds nothing.

Let me know how to get the 'tag number' and I'll send it.

Thanks,
R.

Emm, there are two possible problems.

1. your firmware do not have sdhci driver, please call "lsmod | grep mtk" check if there s a driver named mtk-mmc
2. hardware broken?

the serial number is the last four number of mac address, call ifconfig eth0 you can get mac address.

See below the output of the two commands, it looks like the driver is not there...
I've updated the firmware when I got it, as instructed in "https://vocore.io/v2u.html", with the latest firmware from the Download section.
Maybe that firmware is not up to date?
Is there a newer/better firmware that works better?

See the attachment, from https://vocore.io/v2u.html.
The firmware is dated May 2017, almost 1.5 years old ...
Do you have any newer one?

Since I got no answer I looked around and found newer firmware at http://vonger.cn/misc/vocore2/
I decided to flash the second last one (from April 2018), which was newer than mine.

Now, my VoCore2 doesn't show on WiFi at all, I am afraid that firmware might have bricked it ...

Connected to the device using TerraTerm (i.e. serial term, over the micro-USB).
Forced a restart of the networking, see below the results.
It seems the WiFi is not recognized with the April firmware I flashed on it.
Next I will probably try flashing the latest (August I think) firmware, and if that doesn't work, going back to Jul 2017 one which worked before (but didn't support CF ...).
Anyway, flashing firmware over serial it seems requires shorting 2 internal pins, which means taking apart the case for my VC2U...
Going to bed now ...

That was the one that I was using, I've updated the firmware with the one pointed in that page (the one from 2017), but the issue was that the SD slot was not working.
If you look at the output of lsmod, the driver doesn't seem to be there for that version.
With the other one it seems the driver works, but other things don't.
Is there a particular firmware version where everything works?
