Honored ContributorHi,
--- Quote Start --- I get the following error : Using cable "DE5 Standard [2-1.7]", device 1, instance 0x00 Pausing target processor: OK Initializing CPU cache (if present) OK Downloaded 3523KB in 5.1s (690.7KB/s) Verifying C0000000 ( 0%) Verify failed between address 0xC0000000 and 0xC000FFFF Leaving target processor paused --- Quote End --- The downloader 'nios2-download' will verify whether the downloaded data is correct or not. The error means that the memory contents between address 0xC0000000 and 0xC000FFFF are different from those of your 'vmlinux' file. If you map your main memory from the address 0x00000000, please check the timing of those interface. About the question 'why and how does it reach to 0xC ?', please refer to the Table 2 of https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/nios2/n2cpu_nii51003.pdf Kazu
