do you remember which distro/kernel worked for you? The accelerator example opens /dev/epiphany this way
int mem_fd = -1;
//############################################
//# Map Memory Using Generic Epiphany driver
//############################################
int e_map(unsigned addr, void **ptr, unsigned *offset) {
...
//Open /dev/mem file if not already
if(mem_fd < 1) {
mem_fd = open ("/dev/epiphany", O_RDWR);
if (mem_fd < 1) {
perror("f_map");
return -1;
}
}
but in these distros
parabuntu-2016.11.1-headless-z7010.img
ubuntu-15.04-esdk-2016.3-headless-z7010.img
/dev/epiphany is a folder with some content:
elink0
mesh0
I could not make work this one yet:
ubuntu-14.04-headless-z7010-20150130.1.img
Any hints?

hints:: you have to use the old version of vivado.. 15.2 or 15.4 i think...
else the ip will show as a black box (because it will be empty if you uses the script).
if you are using 15.4, again you have to change the script file to 15.4 from 15.2.
then in the program, you have to change to "dev/epiphany" to "dev/mem"
then only it will map to fpga memory.
thanks and regards
