Omega2+: reboot and sd card fixed!

[D R]

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

[B T]

@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?

[WereCatf]

@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: p1 after those lines you have there, if there is a partition on the card.

[Vinh]

@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

[Paul Kourany]

With v1.9 firmware, the SD is automounted at /tmp/mounts/SD-P1

[Costas Costas]

and if you have a second partition it will be mounted at /tmp/mounts/SD-P2 etc

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

Using a MicroSD Card

Gabriel,

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.

[Lisa Lyons]

I applied the latest update, per your instructions, then decided I'd set up my SD Card per:

https://docs.onion.io/omega2-docs/boot-from-external-storage.html#boot-from-external-storage-mounting-the-external-storage-device

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
