Re: VoCore2 Ultimate - is microSD slot working?
Posted: Tue Oct 02, 2018 4:06 am
In case somebody else does what I did, and needs some hints as to what to do, see below how I managed to solve it in my case.
First the problem.
From what I can tell, it seems I flashed 20170527V.bin (instead of 20170527.bin)
That had issues for me, SDCard was not working.
So then, I flashed a newer one from that webpage (http://vonger.cn/misc/vocore2/).
The issue with that one was that while now the SDCard was working (but for some reason only for cards formatted with FAT, but not exFAT), the wifi didn't, and could not connect over IP (SSH) to it anymore.
To fix it, I had to first find a small SD card formatted FAT (surprisingly hard to find in my house nowadays...)
I copied on it the correct firmware (20170527.bin)
Then, connected my VoCore2, using a micro-USB-to-USB cable, to a computer.
It registered there as COM5 in my case (a W10 PC).
Using TeraTerm, I connected it on that COM5, and set it up with:
- Setup/Serial Port ... ==> 'Speed' set to 115200
- Setup/Font... ==> set to Terminal (that is the name of the font I picked on my PC)
After all that, and after pressing ENTER, I got a root console into my VoCore2.
From there:
mkdir /mnt/sdcard
mount /dev/mmcblk0p1 /mnt/sdcard
cp /mnt/sdcard/20170527.bin /tmp/vocore2.bin
mtd -e firmware write /tmp/vocore2.bin firmware
That last command wiped the firmware and installed the one I specified.
When mtd finished running, I stopped my VoCore2:
poweroff
Then I removed the USB cable, then powered the box back on, and all was once again good with the world.
