Hi , If you can try the compilation on Ubuntu 16.04 or 18.04 that would be helpful , since the issues of compatibility of GLIBC can be avoided. You can also check which version of GLIBC is currently installed in your system to cross verify. Thanks and Regards Anil Replies: Re: Why the following error has occurred when I try to program FPGA? I use Altera board DE1_SoC. OS Ubuntu 18.04 and IntelFPGA 18.1 standard version. Thank you very much!! I have great respect you. I have some issue. After I program FPGA with .aocx file it now successful configured. However, when I try to running host code the following error is generated. So,how I can fix it? /run: /lib/libm.so.6: version `GLIBC_2.27' not found (required by ./run) ./run: /lib/libm.so.6: version `GLIBC_2.29' not found (required by ./run) ./run: /lib/libc.so.6: version `GLIBC_2.17' not found (required by ./run) ./run: /lib/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by ./run) ./run: /lib/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ./run) unfortunately, Upgrade OS Ubuntu 18.04 to Ubuntu 20.04.

Hi You can check the following link on SD card image creation. https://rocketboards.org/foswiki/Documentation/BuildingBootloader#Cyclone_V_SoC_and_Arria_V_SoC Also if possible please use Ubuntu 16.04 and let us know , whether same issue exists. The following guide will be helpful to get info about jtagconfig https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_usb_blstr.pdf Thanks and Regards Anil Replies: Re: Why the following error has occurred when I try to program FPGA? I use Altera board DE1_SoC. OS Ubuntu 18.04 and IntelFPGA 18.1 standard version. Thank you!!! I have no idea creating SD card image with lower JTAG frequency configuration. If you have some note on this idea please share with me. Replies: Re: Why the following error has occurred when I try to program FPGA? I use Altera board DE1_SoC. OS Ubuntu 18.04 and IntelFPGA 18.1 standard version. Hi, If you are using an SD card with pre-built image and using minicom to login to it please let us know the same. In that case you can try creating the SD card image with lower JTAG frequency configuration. Also please try multiple OpenCL examples , like helloworld and simple programs, and let us know whether the issue is still coming.

Thanks I use URTA USB for reprogram the DE1_SoC board via minicom. So, How I can reduce the frequency of URTA or it not? I generated .aocx file by using offline compiler.

Hi Please set the MSEL to 01010 There is a similar issue observed in the following link https://software.intel.com/en-us/forums/opencl/topic/850597 as mentioned there , can you refer to https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/solutions/rd06242013_922.html and try to reduce the JTAG frequency and let us know the results.
