(picture part 4) 7. if everything ok, press "Process". 8. normally it will take 2~3 minutes, please wait until it is ready. note: if power cut off during the upgrade process, your VoCore2 will brick, check "Fix Bricked VoCore2" Compile OpenWRT for VoCore2 video tutorial: youtube (https://youtu.be/ocl6yFtKSNs) 1. install Ubuntu 14.04 64bit Server to Virtual Machine. 2. in virtualbox, we will need install some packages to compile openwrt: sudo aptget install gcc g++ binutils patch bzip2 flex bison make autoconf gettext texinfo unzip sharutils subversion libncurses5dev ncursesterm zlib1gdev libssl dev python 3. download openwrt at "Sources" section in this page, software part. 4. call "tar jxvf openwrt.tar.bz2" to uncompress the package. 5. call "make menuconfig" in the openwrt folder, configure openwrt in menu, choose MT7688/28/VoCore2 in menu. 6. call "make" in the openwrt folder, start the make process Compile your App for VoCore2 1. compile openwrt for VoCore2, it will create toolchain or download it at Downloads/Toolchain(for Ubuntu 14.04 64bit). 2. make a simple code in C, compile it in command line. /path.to.your.toolchain/bin/mipsel‐openwrt‐linux‐gcc ‐g yourcode.c ‐o yourcode 3. after this, you will get an executable file named "yourcode", use scp, copy it to your VoCore2 4. in VoCore2, call chmod +x yourcode , after that, you can run it in VoCore2, call ./yourcode Upload Firmware http://vocore.io/v2.html 8/11 VoCore2 | Coinsized Linux Computer Upload Firmware 1. upload firmware through luci, please read "Upgrade Firmware" section. 2. upload firmware through console, connected to VoCore hotspot. (1) copy from pc to VoCore[operate in PC]: scp [your firmware].bin root@192.168.61.1:/tmp/vocore2.bin here is two choices, 2.a will erase all data/config you write to VoCore, 2.b just upgrade the firmware but keep them. (2.a) write to VoCore nor flash[operate in VoCore]: mtd e firmware write /tmp/vocore2.bin firmware (2.b) system upgrade VoCore nor flash[operate in VoCore]: sysupgrade /tmp/vocore2.bin firmware (3) wait until mtd done, reboot your VoCore. note: if you want set your VoCore back to first time boot up, call "firstboot" in console. Fix Bricked VoCore2 (uboot alive) 1. connect your VoCore2 to computer through USB2TTL(UART2 RXD2+TXD2+GND). 2. open tty tools(must have kermit protocol), such as kermit, ckermit. 3. power up your VoCore, once you find: "0: Load system code then write to Flash via SERIAL.", press '0'. note: VoCore will show "## Ready for binary (kermit) download to 0x80100000 at 115200 bps..." note: kermit: press Ctrl and '\' same time then press 'c', you will switch to kermit command console. 5. send upgrade firmware to VoCore, after that, back to VoCore uboot console. note: kermit: call "send path/to/your/upgrade/file/on/pc.bin" to send firmware, around 10 minutes, once it finished, call 'c' back to console. 6. wait around 20~30 seconds, firmware uploaded, your VoCore will reboot. Fix Bricked VoCore2 (uboot dead) 1. You must have another VoCore/VoCore2 or one flash loader and six wires. 2.1 using another VoCore/VoCore2 to recover your bricked VoCore2. 2.1 check blog http://vonger.cn/?p=8054. 2.2 using flash loader to recover your bricked VoCore2. 2.2.a disconnect VoCore2 from power; 2.2.b connect VoCore2 GND to flash loader GND; 2.2.c VoCore2 +3.3V to flash loader +3.3V; 2.2.d VoCore2 SPI MISO > flash loader SPI MISO; 2.2.e VoCore2 SPI MOSI > flash loader SPI MOSI; 2.2.g VoCore2 SPI CS0 > flash loader SPI CS; 2.2.h VoCore2 SPI CLK > flash loader SPI CLOCK; 2.2.i VoCore2 RST > VoCore2 GND; (keep VoCore2 in reset mode) note: if not work, swap MISO/MOSI. 2.2.j now, download then send "Flash Image" to VoCore2.2. 2.2.k remove wires, connect VoCore2 back to power, everything should back normal. 3. option: better to upgrade your firmware after recover, Flash Image is out of date. Recover factory setting Sometimes, we might mess the factory setting section on VoCore2 flash(address can be find by "cat /proc/mtd"), that will cause wifi driver failed to start. To recover it, we need the following steps: http://vocore.io/v2.html 9/11 VoCore2 | Coinsized Linux Computer 1. get into VoCore console, by ehternet or serial port(TTL). 2. copy mt7628.sh (http://vonger.cn/misc/vocore2/tools/mt7628.sh) to your VoCore2 /tmp, or directly copy the txt in the script and run in console. 3. run mt7628.sh by "sh /tmp/mt7628.sh", then reboot. note: your mac address will be fixed to b8:d8:12:67:01:73, you can change this to modify your VoCore2 mac address. Update UBOOT from serial port 1. reboot vocore2 at serial console, check "Connect to VoCore through USB2TTL" 2. once reboot, it will show "7: Load Boot Loader code then write to Flash via Serial.", now we are ready to send the data. 3. use kermit or compatible tools send uboot.bin, uboot.bin can be get from from Download section. 4. wait until it reboot. Directly write to memory/register We made a simple tool for this, download here (http://vonger.cn/misc/vocore2/tools/mem.zip), its name is "mem", put the executable file into /bin/ in VoCore2. 1. read from register/memory, for example: 0x10000060, pin control register example: mem 0x10000060 2. write to register/memory, must in 32bits(4bytes) example: mem 0x10000064 0x05540555 here is an example bash script flash the LED every second on VoCore2 mem 0x10000064 0x05540555; mem 0x10000604 0x1000; while [ 1 ]; do mem 0x10000634 0x1000; sleep 1; mem 0x10000644 0x1000; sleep 1; done Mount VoCore2 onto customized PCB(ASMT) 1. on customized PCB, suggest keeping 16mm x 16mm rectangle clearance(no copper) for better signal on board antenna. 2. suggest using hot air instead of iron, DDR2 is a ESD sencetive part, might cause permanent damage. 3. must use middle level temprature paste(180C, SnBiAg) or lower one, VoCore2 is using hightemprature paste(220C, SnCuAg), same temprature level might cause damage to VoCore.
