Using cryptech_upload i get a checksum of CRC-32 0x6f23447b. Using the alpha_fmc.bit from the same tarball cryptech_upload is extracting and generating a .mcs file as outlined in <a moz-do-not-send="true" href="https://www.xilinx.com/support/documentation/application.../xapp586-spi-flash.pdf"> <cite class="iUh30">https://www.xilinx.com/support/documentation/application.../xapp586-spi-flash.pdf</cite></a> I get "All Checksum calculations are performed on the address range spanned by the configuration file. '1': Calculated checksum matches expected checksum, 006303f92" when programming with this generated .mcs The FPGA ready led comes on green but gives core error message when trying to set masterkey. Re-flashed using the cryptech_upload --fpga --user wheel command. Once again this command resulted in a checksum of 0x6f23447b and core operations were back to normal. I then performed a "Get Device Checksum" in impact and got this "All Checksum calculations are performed on the address range spanned by the configuration file. ERROR:Cse - '1': The calculated checksum (0x063005bd) differs from the expected checksum (0x06303f92). PROGRESS_END - End Operation." <div class="moz-cite-prefix">On 05/04/2018 12:00 AM, Rob Austein wrote: </div> <blockquote type="cite" cite="mid:20180504050026.EC5EB2003E2BD5@minas-ithil.hactrn.net"> <pre wrap="">On Fri, 04 May 2018 00:00:10 -0400, Michael wrote: </pre> <blockquote type="cite"> <pre wrap=""> One curious thing, if I use the "firmware upload" command while in cryptech_console, I see the blue LED flash as described in the documentation indicating the bootloader is being accessed.
