CloudEngines Pogoplug v4/mobile

The Pogoplug Mobile (POGO-V4-A1-01) and Pogoplug Series 4 (POGO-V4-A3-01) 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).

You need u-Boot 2020.04 from snapshot repository. U-Boot from 19.07 have broken usb and ethernet.

1. Run serial console and go to u-boot.

2. Copy u-boot via tftp and write to NAND:

Pogoplugv4> mw 0x0800000 0xffff 0x100000
Pogoplugv4> nand erase 0x0 100000
Pogoplugv4> setenv ipaddr 192.168.1.2
Pogoplugv4> setenv serverip 192.168.1.4
Pogoplugv4> tftp 0x0800000 openwrt-kirkwood-pogoplugv4-u-boot.kwb
Pogoplugv4> nand write 0x0800000 0x0 0x100000
Pogoplugv4> reset

3. Run new u-Boot, repair bootcmd and restore MAC address from sticker

pogoplugv4> setenv ethaddr AA:BB:CC:DD:EE:FF
pogoplugv4> setenv bootcmd 'ubi part ubi; ubi read 0x800000 kernel; bootm 0x800000'
pogoplugv4> saveenv

4. Copy and run initramfs image

Pogoplugv4> setenv ipaddr 192.168.1.2
Pogoplugv4> setenv serverip 192.168.1.4
pogoplugv4> tftpboot cloudengines_pogoplugv4-initramfs-uImage
pogoplugv4> bootm 0x800000

5. Download sysupgrade image and perform sysupgrade

You need u-Boot 2020.04 from snapshot repository. U-Boot from 19.07 have broken usb and ethernet.

1. Prepare usb fat32 drive with u-boot.kwb and initramfs image. Stick it to USB 2.0 port. 2. Run serial console and go to u-boot. 3. Copy u-boot from usb and write to NAND:

pogoplugv4> mw 0x0800000 0xffff 0x100000
Pogoplugv4> nand erase 0x0 100000
pogoplugv4> usb start
pogoplugv4> fatload usb 0 0x0800000 u-boot.kwb
pogoplugv4> nand write 0x0800000 0x0 0x100000
pogoplugv4> reset

4. Run new u-Boot, repair bootcmd and restore MAC address from sticker

pogoplugv4> setenv ethaddr AA:BB:CC:DD:EE:FF
pogoplugv4> setenv bootcmd 'ubi part ubi; ubi read 0x800000 kernel; bootm 0x800000'
pogoplugv4> saveenv

5. Copy and run initramfs image:

pogoplugv4> usb start
pogoplugv4> fatload usb 0 0x0800000 initramfs-uImage
pogoplugv4> bootm 0x800000

6. Download sysupgrade image and perform sysupgrade.

Eject button

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.

JTAG access points are available on the back side of the board.

TDI	TP19
TDO	TP20
TCK	TP18
TMS_CPU	TP21
RSTn	TP17

There is also TMS_CORE on TP22 but I didn't need this. Instructions for the dockstar devices worked for me.

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.

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?
