Hi Marc,
/dev/roach/mem exists but I'm not sure what the correct numbers are.

So if you go cat /proc/devices there should be an entry for the roach
driver which should tell you the major number, if there isn't such a line
This is what comes up.

Ok, so then /dev/roach/config should be c 252 0 and mem c 252 1. When the
programming
fails, does dmesg tell you anything interesting ?

I do that by running tftpkernel at the R2 bootup instead of tftproot,
correct?
Is there any cleanup I need to do after the reset like when updating
tcpborphserver3?

I am now running the newest kernel on github.
I tried again with progdev and it failed, but I tried
fpga.upload_to_ram_and_program('qdr_err_check_2015_Mar_16_1247.fpg') and it
succeeded.
Could fpga.upload_to_flash('qdr_err_check_2015_Mar_16_1247.fpg') be
exhibiting errors?

yep - printenv will show you what these macros do in case you want to know
more

That looks like you have a kernel which doesn't have the roach2 mmap
Hi Casperites,
I'm trying to program an fpg file onto the Roach2, but I can't seem to get
it to program the fpga.
I keep getting this error:
