Honored ContributorHi all again
I have managed to make /dev/acl to pop up. I thought the driver created it dynamically (alloc_chrdev_region->class_create->device_create) but aclsoc_load script showed me I was wrong. After "mknodding" the entry /dev/acl was ready. Then I run "user" program and it segfaults during mmap test. This is "user" program output ... root@socfpga:~/AOCL/host/driver# ./user Opened the device: file handle# 3!
