Update Intel HLS compilar from 19.4 to 21.4 - Update Intel HLS compilar from 19.4 to 21.4 Hello, I have installed the latest Quartus version 21.4, I am working with the HLS compiler with a Stratix10 MX. With the Quartus 19.4, I never have problems with the device part number "1sm21bhu2f53e2vgs1", using the command: i++ ... -march=1sm21bhu2f53e1vgs1 .. But now, with the update to 21.4, I have a compiler error Error: Device information not found. Device not a legal family or part code (1sm21bhu2f53e1vgs1) Could you please help me with this configuration. Thanks in advance.

I checked your suggestions, then: Available devices in Quartus 21.4, the exact reference of my FPGA (included in Stratix 10 MX development kit -early version 1sm21bhu2f53e2vg s1 ) is not included in the Quartus device list. I removed the last two characters, according to the available names in the Quartus list, to: 1sm21bhu2f53e2vg. Thanks for your help.

Other than that can try install/re-install the specific Stratix 10 device support files under "Individual Files" tab from: https://fpgasoftware.intel.com/ Thanks. Regards, Aik Eu
