Re: Latest FPGA code?

Can anyone (Greg?) confirm that FPGA 1.0.0 (which appears to be the image that accompanies the FRC_2009_v11.zip update, which itself part of the FRC Update 3a package) is really the latest image available? It seems that if a fix was ever implemented, the rev should have been bumped. Hence my wondering.

According to the FRC_ImageVersion.txt file on the cRIO, I've got:

Image: FRC_2009_v11.zip
Date: 1/23/2009
NetComm: 1712
FPGA: 1.0.0

Thanks in advance...
The image you were using did not include the fix in the FPGA. There was a workaround in WPILib that would adjust for the bug.

In the image for this year, the bug is fixed in the FPGA. Look for version 2010 and revision 1.3.0 of the FPGA. The corresponding workarounds in the library are also removed for 2010.

You can look here for a list of changes since 2009. It's still in progress, but the FPGA changes are all there.

Cheers!
