Connect USB - flash memory

I'm trying to connect the flash memory to the device. But I fail. :face_with_head_bandage::roll_eyes:

Have you installed everything needed?

https://openwrt.org/docs/guide-user/storage/usb-drives-quickstart

What version of OpenWrt are you running?

@reza00021 -- If you would let us know which device you're using, we could guide you to a current version of OpenWrt, if available for your device.

version of OpenWrt = 14.07
version of Kernel = 3.10.14
MT_7688

Because I use the kernel 3.10.14, I can not install these packages(block-mount e2fsprogs kmod-fs-ext4 kmod-usb-storage kmod-usb2 kmod-usb3).

But I think there should be no problem:

root@OpenWrt:/lib/modules/3.10.14# ls | grep usb
usb-storage.ko

root@OpenWrt:/lib/modules/3.10.14# lsmod | grep usb
usb_storage            37928  0

MT7688
Open Wrt 14.7
version of Kernel = 3.10.14

The MT7688 chip was not supported in official 14.7 releases. You must have some manufacturer's custom built firmware.
For support of that firmware, contact the manufacturer.

There isn't much about the HLK-MT7688. Maybe it is similar enough to the LinkIt MT7688? https://openwrt.org/toh/seeed/linkit7688

Looks like the source might be available at https://github.com/MediaTek-Labs You should confirm that it is the proper software for your board, perhaps from the vendor of your board.

"Best" would be confirming with that source that the hardware and flashed firmware is the same as what mk24 linked and moving to current, supported OpenWrt.

Building from that source might also be possible.

Note : LinkIt Smart 7688 uses the MediaTek proprietary Wi-Fi driver. While OpenWrt Chaos Calmer is evolving, only selected Linux kernel versions of it are supported by the Wi-Fi driver (3.18.21 ~ 3.18.44). If you are looking for a non-proprietary Wi-Fi driver, the mt76 project would be a reference of the choice.
