Now we already have the firmware, I also upload it to http://vonger.cn/misc/vocore2/20190127.bin How to use upgrade to this firmware? Connect to VoCore2 by network: ethernet or wifi both is good. Open browser by 192.168.61.1, username root, password vocore. In the top menu, select System -> Backup/Flash firmware -> Uncheck ‘Keep settings’ -> Click ‘choose file’ […]

Final puzzle piece for the firmware, the sound. I spend some time to clean up my last patch, its works perfect now. It is still all in http://github.com/vonger/vocore2. patch openwrt first to enable sound setting in DTS(default it is off), and 810 patch is for linux kernel sound driver. patch -p1 < ./package/kernel/es8388/openwrt/000-*.patch cp ./package/kernel/es8388/openwrt/810*.patch […]

1,2,3 is enough for VoCore2, for VoCore2 Ultimate, we still missing a lot of drivers and app. sound driver, such as madplay, asound, arecord can be download from openwrt by opkg, so we do not imply them. camera driver, we include it this time. sdcard drive, this is necessary. file system driver, support vfat. tools […]

OK, now install luci for noobs 🙂 install LuCI for openwrt. ./scripts/feeds update luci ./scripts/feeds install -a -p luci note: if you download speed is slow from openwrt.org, you can modify ./feeds.conf.default, change its ‘https://git.openwrt.org/feed/’ to ‘https://github.com/openwrt/’, then do it feeds update/install again, github should be much faster. After this we have LuCI, as usual, […]

And point 1,2,3, openwrt do not allow me submit patch, because it will broken other device. Point 3 is pretty important, use official mt76 driver, wireless […]

Actually there is a lot of tutorials already, but maybe we need to restart a full version.

If […]

I think we need a stable version based on 18.06 for beginner 🙂 So this week I am going to work on a firmware. And I will also write how I do this to help beginner of openwrt. Targets: 1. port mt7628 driver for 18.06. 2. port sound driver for 18.06. 3. fix possible SD […]

OpenWrt 21.02.2 is pretty stable, the even better part is it supports WPA3. Official OpenWrt 21.02.2 release directly work with VoCore2 SBC version, but for VoCore2 Ultimate version, we have some external devices need to be supported, so this blog and following blogs I will write down the process I patch OpenWrt 21.02. There are […]

Because current 4inch screen(based on driver board v10a) is designed for very low power usage and intend to be long life time, so we have to limit its backlight brightness to save power. But currently maybe people do not care about the power usage and backlight lifetime, so I write this blog to provide a […]
