Hello,

 

we are trying to use Arria 10 on Intel DevCloud to compile some OpenCL code, however the device status is "Uninitialized". This has worked before, however in the last two days it is not working. Please advise us what to do.

 

I'm providing the output of "aocl diagnose" command:

 

u172aaa@s005-n002:~$ aocl diagnose

/etc/OpenCL/vendors

 

Found 2 icd entry at that location:

/etc/OpenCL/vendors/Altera.icd

the following OpenCL libraries are referenced in the icd files:

libalteracl.so

checking LD_LIBRARY_PATH for registered libraries:

Trying to program the device also generates a problem.

 

u172aaa@s005-n002:~/A10_OPENCL_AFU/vector_add/bin$ aocl program acl0 vector_add_fpga.aocx

aocl program: Running program from /opt/a10/inteldevstack/a10_gx_pac_ias_1_2_1_pv/opencl/opencl_bsp/linux64/libexec

libopae-c reconf.c:450:fpgaReconfigureSlot() **ERROR** : PR incompatible bitstream error detected

Error writing bitstream to FPGA: reconfiguration error

Hi,


We are sorry for the delay. 


You can run the below command.


aocl initialize acl0


Since the BSP is properly installed this will initialize the FPGA and have it ready for programming.

 

Thanks,

Aayushi
