<p>It's not an Arduino, it's a USB dongle to communicate with

<div>Thanks for explaining the situation to me. I'll get hold of
an Arduino and give this a shot.</div>

<p>Last attempt I saw was here <a

<p>but it was rejected.</p>

<p>I have some experience with the bootloader used in this
device, I can <br>
</p>
<p>provide more complete instructions to do the uboot fix
though.</p>
<p>TTL/serial access seems to be easy (there is a header as
you see in the photo),</p>
<p>and you need an inexpensive "arduino USB-TTL dongle" to
connect to this device.<br>
</p>
<p>Connect the pins as defined in the wiki, open up your
serial <br>
</p>
<p>communication program (Putty usually)</p>
<p>and set it for 115200 serial speed, others default.<br>
</p>
<p>Then boot the device, press a key to stop boot when you
see <br>
</p>
<p>"Hit any key to stop autoboot: 2 1 0"</p>
<p>It should stop and accept console commands.<br>
</p>
<p> then copy-paste this line <br>
</p>
<p>setenv sleep 1;nmrp;sf probe 0:3;sf read $loadaddr
0x30000 0x400000;bootm $loadaddr</p>
<p>This will alter the bootloader configuration that is
causing the issue. Now it will boot kernels up to 4MB big</p>
<p>Will still be able to boot stock firmware, we are just
increasing a size limit.<br>
</p>
<p>and then save the change by writing</p>
<p>saveenv<br>
</p>
<p>and then you can reboot the device by pulling the plug or
writing<br>
</p>
<p>reset</p>
<p>Now you can install OpenWrt as normal.<br>
</p>

<div>I was wondering if a patch enabling this device was

<div>The wiki suggests one can only install/boot into
OpenWRT by wiring up a JTAG/serial interface and
manually intervene... Which is far beyond my comfort
zone.<br>
</div>

</div>
<div>Am very eagar to make use of this equipment, so any
