DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details. 1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation. This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now. 2) OpenWrt support for this device will end after 2019. 19.07 will be the last official build for 4/32 devices. After 19.07, no further OpenWrt images will be built for 4/32 devices. See OpenWrt on 4/32 devices what you can do now. VoCore is an open hardware device which runs OpenWrt by design. It includes WiFi, USB, UART (serial), SPI, and more than 20 General Purpose IOs (GPIO) in a small, one inch package. It can be used for automation projects and is an excellent tool for learning about and implementing embedded systems.

I did not try to do an upgrade. It booted properly the first time but after doing a uci commit from the commmand line it would not boot . It gave a out of memory kernel panic.

OEM installation using the TFTP method →generic.flashing.tftp Basic configuration The board comes preflashed and ready to run. It is accessible over open wifi (SSID Vocore) or the ethernet port. The IP address for the alpha and beta releases is 192.168.1.1 The IP address for release version 1 is 192.168.61.1 The default address from images downloaded from OpenWrt is 192.168.1.1 For security reasons wifi access should be changed to limit/protect using WPA. Specific Configuration Interfaces The default network configuration is: Interface Name Description Default configuration br-lan LAN & WLAN 192.168.1.1/24 vlan1 (eth0.1) LAN None radio0 WLAN Disabled Switch Ports (for VLANs) Only 2 of the 5 ethernet ports have been exported: 0 and 4 (1, 2 and 3 are not exported). For using port 0 a separate dock is needed (like VoDock). However, port 4 is not avaiable on VoDock and needs a custom dock. Port Switch port LAN 1 0 LAN 2 4 Failsafe mode → failsafe_and_factory_reset To enter Failsafe mode you need to manually pause OpenWrt booting, since this board doesn't have any button. Buttons → hardware.button on howto use and configure the hardware button(s). This board doesn't come with any button. However, new buttons can be added using one of the unused GPIOs.

On the production run though there where no 8MiB chips available and therefore (not only buyers of the 16MiB version but) everyone got 16MiB flash. So if the VoCore is labeled as v1.0 it probably got 16MiB flash, but better make sure by looking at the flash-chip (8 pin Winbond chip): Flash chip Flash size 25Q64 8MiB 25Q128 16MiB The default configuration for OpenWrt is 8MiB flash (which can also be used on the 16MiB version, with less available space of course). To create a 16MiB image compiling yourself is necessary. In target/linux/ramips/dts/VOCORE.dts there's a section partition@50000. Change the second value of reg from 0x7b0000 (=8MiB config) to 0xfb0000 (=16MiB config).

However, don't forget to remove the GPIOs you want to use as buttons from the LEDs/GPIOs sections, since a specific GPIO can only be used for one purpose at a time. gpio-keys-polled { compatible = "gpio-keys-polled"; #address-cells = <1>; #size-cells = <0>; poll-interval = <20>; reset { label = "reset"; gpios = <&gpio0 0 0>; linux,code = <0x198>; }; }; Bootlogs OpenWrt Bootlog [ 0.000000] Linux version 3.10.32 (vonger@debian) (gcc version 4.8.3 (OpenWrt/Linaro GCC 4.8-2014.01 r39957) ) #3 Thu Mar 20 21:56:24 HKT 2014 [ 0.000000] SoC Type: Ralink RT5350 id:1 rev:3 [ 0.000000] bootconsole [early0] enabled [ 0.000000] CPU revision is: 0001964c (MIPS 24KEc) [ 0.000000] MIPS: machine is VoCore v0.3 [ 0.000000] Determined physical RAM map: [ 0.000000] memory: 02000000 @ 00000000 (usable) [ 0.000000] Initrd not found or empty - disabling initrd [ 0.000000] Zone ranges: [ 0.000000] Normal [mem 0x00000000-0x01ffffff] [ 0.000000] Movable zone start for each node [ 0.000000] Early memory node ranges [ 0.000000] node 0: [mem 0x00000000-0x01ffffff] [ 0.000000] Primary instruction cache 32kB, VIPT, 4-way, linesize 32 bytes.
