sbl2e dualserial factory image web pages are corrupt

Just got my SBL2E kit, and the learning curve is kinda steep, so I don't know what to make of this.

The code ran just fine out of the box, and the configuration web pages are as expected.

I modified dualserial, loaded it up, and of course it didn't work as I expected. All non-trivial programs contain bugs....

I went to the factory original image of the dualserial app, and loaded it with MTTTY (because my sbl2e disappeared from NBFIND and AutoUpdate.) After rebooting, all the served up web pages are odd, to say the least.

For example, here's what's in the examples/sbl2e/dualserial/html/index.htm, near the top:

<html>

<script type="text/javascript">
...

but here's what get's served up:

�>

� type="text/javascript">
...

In fact, except for the passwordgroup, every instance of <anything is replaced by �. "<html>" becomes "�>", while "<body bgcolor...>" becomes just "� bgcolor...>". No current values of ip_Addr/MyIpAddr or ip_Mask/MyIpMask are served up:

working:

<tr>
<td>
<font size="2">Device IP address:</font>
</td>
<td>
<input name="v02DeviceAddress" size="20" value="0.0.0.0" type="text">
</td>
<td>
<font size="2">192.168.1.115</font>
</td>
</tr>

not working

�>
�>
� size="2">Device IP address:�>
�>
�>
� name="v02DeviceAddress" size="20" value="" type="text">
�>
�>
� size="2">
�>
�>

My hex editor shows the "�" to be 0xEFBFBD sequence.

It sort of looks like the code that's supposed to serve up the web page, while stripping things like PASSWORDGROUP, and filling in VARIABLE values, is...well, I don't know what it's doing. The VARIABLE fields are getting removed, but they're not being filled in with the variable values.

Any ideas? Anyone?

Thanks,
jmh

update--I loaded SBL2E-AppR1P65/SBL2E-App_APP.s19 and the problem isn't there. I assume there is some kind of version mismatch between the NNDK 2.6.4 "original" dualserial code and the update monitor running in my SBL2e. If anyone has a better idea I'd love to hear about it, but I'm moving on.

In your first post, where did you get the image from? You're running into a compression issue I believe. (The L2E doesn't have enough RAM to decompress webpages, and so they must be stored raw, unlike other platforms; it's a flag for comphtml).

The first "factory original" image I flashed came from C:\nburn\SBL2E\original\dualserial_APP.s19. I did not try dualserial.s19. These are in the NNDK 2.6.4 release.

The second "factory original" I flashed was SBL2E-AppR1P65/SBL2E-App_APP.s19, downloaded from NetBurner site. see http://www.netburner.com/support/docume ... e/349-50-2.

It turns out that the makefiles for SBL2E projects were missing the "no compression" flag on the call to comphtml. Therefore the 'original' app image was being built wrong. This image is different than the version loaded onto the devices as that image is fully constructed including the bootloader and is a more manual procedure. This issue has been corrected.
