Happened to me sometimes as well, doesn't seem to be smth severe. At least the devices keeps functioning without side affects.

423

I want to test this driver for stability, but i can't compile LEDE with 4.4 kernel...

Compilation fails at ".../dtc/dtc No such file or directory". :frowning:

I have no such a problem with 4.9.

424

Has somebody tried samba on this router? I have bad performance especially write speeds are slow (about 20MB/s) over GbE. Reads are normal (about 50MB/s). CPU isn't overloaded, it is about 20% load. Also I cannot manage to use my JMS567 USB3.0 UAS SATA adapter. It is found by lsusb, but not in /dev/sda1. So I must use another USB 3.0 SATA adapter. What do you recommend to do?

425

There are 2 cores with 4 threads, so when it says 25% you're maxing one core. I think that's the limiting factor.

426

Format to ext4. Must be Read 80/ Write 30MB/s

427

Do you have any special configuration for mount or samba? Which protocol will be faster? Maybe ftp or a protocol that uses multicore

428

Can someone please help me. I can't manage to mount a fat32 usb stick. Where can i find a guide?

I see that now on GitHub there are two branches :smiley:
Do I have to change the feed
src-git mtk https://github.com/Nossiac/mtk-openwrt-feeds;lede-17.01
to
src-git mtk https://github.com/Nossiac/mtk-openwrt-feeds;master ?

Thanks

431

i can't see the device under /dev/sdaX, even though the usb is plugged in and recognised

usb 2-1: new SuperSpeed USB device number 2 using xhci-mtk

432

I had the same problem. Do you use JMS567 or any UAS controller? Because I have to use another controller to work.

433

where can i check?

434

you must install usbutils with command opkg update & opkg install usbutils. Then you can check with command lsusb. You will see your devices.

this is what i get, but if I run ls in /dev, i can't see anything like sda0 or something.:scream: please help i am still a noob with lede

436

I cannot find this in LEDE trunk. Do you happen to have a link to this particular commit?

437

Did you install all packages? Little tip: https://medium.com/openwrt-iot/lede-openwrt-setting-up-usb-storage-support-adec9c0d484e

439

Still it recognise the usb stick but i don't see it under /dev/sd*

I have installed the pakages with the--force-depends option, because they required a newer version of the kernel. Maybe that is the problem?

--edit
thank you all guys, solved by updating the kernel

440

is it possible to flash original firmware or padavan with this method ? I have no backup...
