found the solution for now:

opkg update
opkg install kmod-sdhci-mt7620

now i have another module listed: mtk_sd
sd-cards are detected properly

Here's the output:

# lsmod | grep mmc
mmc_block              28144  0
mmc_core               92224  2 mmc_block,sdhci

# cat /etc/config/fstab

config global
        option anon_swap '0'
        option anon_mount '1'
        option auto_swap '1'
        option auto_mount '1'
        option delay_root '5'
        option check_fs '0'

@crispyoz said in sdCard slot for Omega2 O2:

When you insert the sdcard is there any entry in the syslog?What firmware version are you using?

Ω-ware: 23.05.3 b20240807
logread and dmesg doesn't change when inserting and ejecting cards

i've compared mmc kernel modules with:

lsmod | grep mmc
lsmod | grep sd

the output looks similar on both systems.

also i've checked the OMEGA2.dtsi in docker buildroot and in openwrt, they also looks the same.

here is my linux knowledge ends

I also tried beta 22, it doesn't see cards either.

@crispyoz, you've given me the idea to try another firmware.
I was on beta OpenWRT 23.05.
I've flashed b258, and ---drum roll--- sd-card is recognized and mounted automatically!
That's a relief.
But, what should I do to enable it in beta fw? How can I help?

Hello, Onioneers!
I have two Omega2 boards from early bird batches with that wierd labels. It's Omega2 without '+', but model is O2P.

I need sd-card slot for my pet project. I have found and purchased Molex 503398-0891 (also Molex 503398-1892 can be used).

So, I've soldered:

• the slot
• five 10k resistors on bottom
• one 10k resitor on top
• two capacitors (4.7uF and 0.1uF) on top.

I've tried to compare inside photos from FCC. But quality is not good.

And as a result - no luck, so far. Inserting sdCard doesn't trigger anything in system.
What am I missing? Is the difference between O2 and O2P firmware right about SDIO interface? Should I insmod something, or reflash another bootloader?

I've looked through the community but didn't find much. And sadly there is no O2/O2P schematics.
Has anyone been able to do what I'm doing? Thanks for any help.
