Hello,
I've acquired a Ravpower RP-WD02 and will try to have OpenWrt working on it.
I've started recognition phase and before going further, I'll wait for my USB2Serial adapter to arrive in order to have full view on the uBoot logs.
Many information have been gathered already and have been written down to the wiki : http://wiki.openwrt.org/toh/ravpower/rp-wd02
Waiting for the missing hardware to arrive, I'm trying to find a way to identify the GPIO ports but I'm stuck at this step. I've checked the existing doc which recommend to check through /sys/class/gpio the various gpio available and their behaviour.
I do not have such /sys/class/gpio on my device. I've search through the various class on sys and dev but did not found any gpio related one.
What I've found is the /bin/gpio command line utility which got the following documentation :
Usage: gpio w - writing test (output)
gpio r - reading test (input)
gpio i (<gpio>) - interrupt test for gpio number
gpio l <gpio> <on> <off> <blinks> <rests> <times>
- set led on <gpio>(0~24) on/off interval, no. of blinking/resting cycles, times of blinking
Unfortunately, when I try to leverage this tool to identify the gpio, I got either no output or an error message (/dev/gpio: No such device or address).
Looks like this is related to the current kernel of the device which does not provide access to gpio (no gpio driver message seen in the boot log) and potentially, required module are not part of the kernel build.
Potential missing part is related to :
Sysfs Interface for Userspace (OPTIONAL)
========================================
Platforms which use the "gpiolib" implementors framework may choose to
configure a sysfs user interface to GPIOs. This is different from the
debugfs interface, since it provides control over GPIO direction and
value instead of just showing a gpio state summary. Plus, it could be
present on production systems without debugging support.
I'll update this post depending on my progress or any help given by this great community.
One interesting information found in the existing firmware is about the list of vendors/models that looks similar based on RT5350 :

Updated on 02/01/2015 :
I used binwalk on the various mtd backups I've made.
Here is the content :
MTD8 (RootFs)
DECIMAL HEXADECIMAL DESCRIPTION

and more interestingly :
MTD1 (u-Boot)
DECIMAL HEXADECIMAL DESCRIPTION

104736 0x19920 U-Boot version string, "U-Boot 1.1.3 (May 14 2014 - 12:33:39)"
This provide the info about U-Boot 1.1.3.
I've then extracted uboot and run strings on it and I gathered some information (that I will need to confirm when my USB2Serial will arrived) :
Please choose the operation:
%d: Enter IOVST ui menu.
%d: Load system code to SDRAM via TFTP.
%d: Load system code then write to Flash via TFTP.
%d: Boot system code via Flash (default).
%d: Entr boot command line interface.
%d: Load Boot Loader code then write to Flash via Serial.
