Omega2+: reboot and sd card fixed!
@B-T If your card is formatted with a supported filesystem it should be available under /tmp/run/mountd/mmcblk0p1 or similar automatically as soon as you insert the card. You can check free space on the card and where it is mounted simply by calling
dfon the command-line.
So I can see my SD card and I can write to/read from it but I'm still not sure if it can be used for installing packages etc
@WereCatf not showing the card when running
df, my card is 32 GB and the closes to it is
/dev/mtdblock6 25728. I did check the path you shared with me and it looked like there was something with the size of my card. Is this the path where I should be checking to get to my card?
@B-T What do
df -h|grep "mmcblk0"and
ls -l /dev/mmcblk*give you?
Setting up Omega2+ is more a frustration compared to Raspberry Pi or Arduino.
Anyone knows a workaround to get SD Card working (I already tried build 149)?
df : always doesn't show the card
dmesg shows me my card:

@Vinh-Tran Have you formatted the card? It's supposed to also spit out a line similar to
mmcblk0: p1after those lines you have there, if there is a partition on the card.
@WereCatf sorry, figured out that the latest system is too lazy. it didn't mount the sd card.
I solve it by creating a new folder and using mount command.
I also edited my previous post with the missing information
With v1.9 firmware, the SD is automounted at

We just released a quick tutorial on how to work with SD cards here: Using a MicroSD Card.

Using a MicroSD Card
I'm assuming that the card needs to be pre formatted to FAT 32 or something similar? The tutorial makes no mention of supported formats hence the question.
I use a Mac at home so if I format any cards I would need to ensure that I choose an appropriate option.

Mine was read/writable when i plugged in. It came Fat32 formatted.
If you want to use it as a boot able memory you need to format it to ext4.
Here's a tutorial of how I'm using the SDCARD on my device. My use-case is pretty specific, though you can modify my instructions to your own needs.
I applied the latest update, per your instructions, then decided I'd set up my SD Card per:
For some reason, while the "block detect" command did come up with a useful output, I couldn't redirect that output to /etc/config/fstab - So I did it manually!
However, despite working through all of that, on reboot the Omega 2+ I have doesn't remember there was an SD card in the slot! I have to eject the SD Card, and reinsert it, and then the OS sees it.
Which means that I can't boot from it....
I have the same problem that the last comment
