 +====== Pogoplug v4/​mobile======
  
 +The Pogoplug Series 4 (POGO-V4-A3-01) and Pogoplug Mobile (POGO-V4-A1-01) are low-cost backup and media sharing devices based on the Marvell Kirkwood (ARM) CPU. The Pogoplug Mobile is notable for its low cost (< $10 USD).

 +Don't mix up the POGO-V4-**A1**-01 (blue-ish logo, see above) with the POGO-V4-**A3**-01 (redish logo), which is shown here:\\

 +
 +Case may be opened by removing screws beneath two rubber feet at back of device, then lifting while prying the sides of the upper part out to unhook a latch on each side about 2/3rds of the way toward the front.

 +
 +Serial connection is at J11, left of SD as you face SD opening. Pins are 0V, Rx, Tx (moving right to left from SD). Do not connect +V pin. Make sure your serial device is 3.3V, not 5V. Baud rate is 115200.
 +
 +===== GPIO =====
 +There are at least 12 usable GPIO on this board excluding the serial console pins. Below is an image with the ones I've found so far.
 +
 +{{media:​pogoplug:​pogoplug_mobile_gpio_large.jpg?​600}}
 +
 +In addition to these the two LEDs can also be repurposed. The green LED is GPIO22 and the red LED is GPIO24. There are also two unpopulated LEDs on the bottom of the board close to the 6192 processor marked LED7 and LED8. LED7 is GPIO23 and LED8 is GPIO21. The pad closest to the processor is tied to the pin.
 +Here is the hardware peripheral mapping (http://​free-electrons.com/​kerneldoc//​latest/​devicetree/​bindings/​pinctrl/​marvell,​kirkwood-pinctrl.txt). Can anyone verify this? Seems strange to have MISO as output only, could be other errors?

 +===== Installation =====
 +**Warning**:​ This information has been compiled from various sources and has not been verified. Proceed with caution as you risk bricking your device.
 +
 +OpenWrt installation for the Pogoplug Mobile uses the [[http://​downloads.openwrt.org/​snapshots/​trunk/​kirkwood/​|image for the (older) Pogoplug E02]] and largely follows the procedure for the [[:​doc:​howto:​dockstar_sandbox|Seagate Dockstar]]. ​
 +
 +==== Steps ====
 +
 +According to [[https://​forum.openwrt.org/​viewtopic.php?​id=51769|this forum thread]], the steps for installing OpenWrt on the Pogoplug Mobile (and booting from USB) are:
 +
 +  - Follow [[http://​blog.qnology.com/​2014/​07/​hacking-pogoplug-v4-series-4-and-mobile.html|this guide]] **up to** (and including) the step "Boot default Pogoplug OS when USB/SD Card not attached (optional)"​
 +  - Follow the section "​Installing OpenWRT onto a USB stick or HDD" in [[:​doc:​howto:​dockstar_sandbox#​additional.resources|this guide]] to install onto USB **but**:
 +    * use ext3 (not ext2)
 +    * place the uImage file in the /boot folder.
 +Note that if you have serial console, you don't need the ssh access which the above instructions call for.
 +==== Not working/​tested ====
 +
 +  * Eject button
 +
 +[[https://​forum.openwrt.org/​viewtopic.php?​pid=186323#​p186323|NAND installation for the E02]] works, and the same process works for the Pogoplug Mobile. [[http://​wiki.beyondlogic.org/​index.php?​title=GuruPlug_Building_Kernel|This link]] has some good information on writing the kernel to the nand, and [[:​toh:​cloudengines/​pogoplug#​installing.rootfs.including.kernel.and.devicetree|this link]] shows how to write a ubifs image from u-boot. Don't forget to add ${mtdparts} to your bootcmd, excluding this and an errant ubiattach -p /dev/mtd0 meant I had the pleasure of figuring out JTAG on these devices.
 +
 +Another link for nand installation of ubifs: http://​blog.qnology.com/​2015/​02/​openwrt-on-pogoplug-mobile.html ​ The instructions are for Trunk, but also work for CC 15.05
