OpenCL + Cyclone V SoC

--- Quote Start ---

Having RTFM more carefully I've made a bit of progress. I've added this:

export AOCL_BOARD_PACKAGE_ROOT=$ALTERAOCLSDKROOT/board/c5soc

which results in this:

$ aoc --list-boards
Board list:
  c5soc
$ make
/usr/bin/ld: skipping incompatible /home/jim/altera/13.1/hld/board/c5soc/host/arm32/lib/libalteracl.so when searching for -lalteracl
/home/jim/altera/13.1/hld/board/c5soc/host/arm32/lib/libalterahalmmd.so: could not read symbols: File in wrong format
collect2: ld returned 1 exit status
make: ***  Error 1
$ cd device
$ aoc hello_world.cl --board c5soc
Error: aoc: Can't find a valid license for the Altera SDK for OpenCL

I've also now read about the LM_LICENSE_FILE environment variable, but since I'm using the web edition of Quartus I don't have a license.dat. Is there any way of experimenting with this stuff on a Cyclone V without buying a Stratix V license?

Hello Jim

You are trying to compile/link arm code using x86 tools. First of all you have to install linaro tool chain for cross-compiling arm apps in x86. Mine is in /opt/altera-linux.

1) Modify your PATH environment

export PATH=$PATH:/opt/altera-linux/linaro/gcc-linaro-arm-linux-gnueabihf-4.7-2012.11-20121123_linux/bin/

2) Modify Makefile to use arm toolchain

...

# OpenCL compile and link flags.

AOCL_COMPILE_CONFIG := $(shell aocl compile-config)

AOCL_LINK_CONFIG := $(shell aocl link-config)

# Cross compiling stuff

CROSS_COMPILE = arm-linux-gnueabihf-

...

$(ECHO)$(CROSS_COMPILE)g++ $(CXXFLAGS) -fPIC $(foreach D,$(INC_DIRS),-I

$(AOCL_COMPILE_CONFIG) $(SRCS) $(AOCL_LINK_CONFIG) \

$(foreach D,$(LIB_DIRS),-L$D)

$(foreach L,$(LIBS),-l$L)

...

Just make and that's all.

This is the easy part. There are some steps missing

1) Generate FPGA kernel .aocx using aocl (I don't have an AOCL lic yet :-( )

2) Get a working device driver running in arm host. I can compile and insmod the host driver (arm) but it cannot pass the tests (see my last post)

I think we need support from Altera people (Dimitry Denisenko is the author of the host side driver ...)

Good luck
