Arria 10 encrypting split FPGA bitstream


I’m working with an Arria 10 that’s part of a product in development. We want to split the SOF into its core and periph parts and encrypt both. Has anyone done this? I can create a single RBF and encrypt it, set the volatile key, and see early release come up.

However, encrypting core and periph RBFs with qcrypt (17.1.0) results in qcrypt complaining about “Unexpected end of file” and technical support has been less than stellar.

If I’m wasting my time and we have to use the single SOF and put up with the increased boot time it would be good to know!
