It seems like a useful feature to have. An 351 Naik (16) Author Affiliations 16. Injecting the Error with quartus_jli Executable A JAM file was created called inject.jam. I can't believe that Altera announce its partial reconfiguration support when there is a such obvious bug, although not many people use it in product environment.
Make sure your memory write addresses (when the MAC is receiving data) are 32-bit word aligned. Scripting Information Keyword:crc_error_open_drain Settings:on | off *default Enable internal scrubbing: If this option is Have you tried another board? Using the JTAG programmer to do the partial reconfiguration instead of using PCIe to transfer the rbf file.
Gad (16) Rajendra S. Under certain circumstances (combination of loading and varying byte sizes), an incorrect amount of data gets transferred from the MAC. An 357 Pill IEEE Transactions on Computers 57(11), 1550–1560 (2008)MathSciNetCrossRef21.Nguyen, G.D.: Fast CRCs. Cricinfo Conf.
I can't promise any of these will help but they are issues we had trouble with. 1 - Memory alignment. IEEE Transactions on Computers 52(10) (2003)24.Albertango, G., Sisto, R.: Parallel CRC Generation. IEEE Trans. Details on the Serial Flash Loader are here: http://www.altera.com/literature/an/an370.pdf The design uses CLKIN_50, pin AN6, on the devkit, which is a 50 MHz clock.
Have you made a change to software, firmware, or hardware?

Enable error detection CRC: If turned on, enables error detection CRC and CRC_ERROR pin usage for the targeted device. The Serial Flash Loader is not required to use the CRC_ERROR feature and was simply in the design to illustrate another feature. This caused a lot of issues (like occasional CRC errors). I changed the settings of the MAC to forward packets to the application even if a CRC-32 error is detected.
The system returned: (22) Invalid argument The remote host or network may be down. When you use a FIFO, and/or a shift-RAM in the reconfigured region, you have 99% probability to get that problem. I don't think it is associated with any of the problems you highlighted above unfortunately. The data that I receive looks somewhat correct, but some bytes are repeated.
Tampere University of Technology Authors Vinaya R. The latest sv boards have the fix for it. Your cache administrator is webmaster. You'll notice in the Altera InterNiche driver that they use the 16-bit shift feature of the MAC to accomplish this. 2 - Known bug.
Cyclic Redundancy check Codes (CRCs) are used in embedded networks for effective error detection. Register Help Remember Me? You know it is really bad for me because the machine is shared by a lot of people (that's why I want partial reconfiguration online), I have to email to every I wrote a custom driver for it (though it is very similar to the Altera driver) to support a different stack.
