Re: [casper] Failed to build Casperfpga

Hi Bishnu, It looks like the culprit is progska - which is a c program included in the library for programming the SKARAB boards. You could manually remove the dependency (you won't need it for rfsoc work) but it may be easier to install the required os packages. You will almost certainly need

Re: [casper] Error in Matlab running startsg

Hi Ben, I just took a look and this seems to an issue with the model. - Some of test models in that folder appear to be out of date, and this particular test file used a custom bit of code to test the crc of the packet that looks like it was not checked in along with the model, so the model can't
