ContributionsMost RecentMost LikesSolutionsUnexpected reboot during programming of Arria 10 I'm following the document AN-807 to try and bringup Arria 10 for OpenCL FPGA use. I'm on Windows 10. When executing "quartus_pgm -c 1 -m JTAG -o "p;top.sof", I got an unexpected reboot. This worked for me previously but is suddenly not working anymore. So I went to the troubleshooting section that tells me to execute "aocl flash acl0" - the document says I should get "flash.cof" and "flash.cdf" files after executing that command but I don't get any files at all. So now I'm stuck and can't proceed. Please help. @BoonBengT_Altera aocl install failed Re: aocl install failed Thanks @BoonBengT_Altera . Disabling signed driver verification was the necessary missing step. Re: aocl install failed Hi @BoonBengT_Altera, I do not have Ubuntu installed. I'm using Windows 10 version 1909. There is no mention anywhere that we have to work in non-Windows environment. I've attached screenshots of all the steps that I've performed until I encountered 'aocl install failed'. Best regards aocl install failed I recently bought the Intel Arria 10 GX FPGA and wanted to use it with OpenCL. My system is Windows 10 and I inserted it into an ASUS RS720-E9-RS8-G server. I was able to follow AN807's "Initializing the Intel Arria 10 GX FPGA Development Kit for use with OpenCL" completely without any error. However, when I tried to run "aocl install" (with admin privelages) as described in the next section "Installing the OpenCL Runtime Driver", I got an install failed. I am using the Arria 10 reference BSP that comes with Quartus Prime Pro release 19.2. Solved
