[Bug 865266] [NEW] [SRU] Ethernet library: read from Socket broken

[Launchpad Bug Tracker]

SRU proposal for Arduino in 11.10 (oneiric)

[Impact] When using the ethernet library and the version of gcc-avr in
oneiric, the ethernet shield (i.e. ethernet port on an arduino) doesn't
work. This is a very heavily used package in Ubuntu, and many of the
users have the ethernet shield

[Development fix] Fixed in Debian Experimental, requestsync for precise.
They use the same patch as posted here. Upstream has this bug report and
pull request, but hasn't applied it yet.

[Stable fix] See below debdiff

[Test case]: requires specific hardware, but just try compiling the
sample webserver for arduino and use it, it won't work. I (showard314)
don't have the ethernet shield, but this has been reported in the forums
for arduino and the proposed fix in PPA form has been confirmed by two
users below.

[Regression potential] Patch only affects ethernet library, and it
doesn't work now - so it can't get any worse.

original report below:

Using the Ubuntu version of arduino-core and avr-gcc makes it impossible
to get the example Arduino Webserver working.


Reading from the Socket returns garbled output.

The Arduino forum has found as solution, which works for me:

I've attached a patch for /usr/share/arduino/libraries/Ethernet/utility/w5100.h
