Updating the Hardware Image on the FPGA
If applicable, before you execute an OpenCL kernel program on the FPGA, ensure that the flash memory
of the FPGA contains a hardware image created using a current version of the OpenCL software.
Remember: If your Custom Platform requires that you preload a valid OpenCL image into the flash
memory, for every major release of the Altera Complete Design Suite, program the flash
memory of the FPGA with a hardware image compatible with the current version of the
software.
Querying the Device Name of Your FPGA Board
Some AOCL utility commands require you to specify the device name (<device_name>). The
<device_name> refers to the acl number (e.g. acl0 to acl15) that corresponds to the FPGA device. When
you query a list of accelerator boards, the RTE produces a list of installed devices on your machine in the
order of their device names.
• To query a list of installed devices on your machine, type
aocl diagnose
at a command prompt.
The software generates an output that resembles the example shown below:
aocl diagnose: Running diagnostic from ALTERAOCLSDKROOT/board/<board_name>/
<platform>/libexec
Verified that the kernel mode driver is installed on the host machine.
Using board package from vendor: <board_vendor_name>

Programming the Flash Memory of an FPGA on Linux
By default, you configure an FPGA using the hardware image stored in the flash memory of the device.
When there is no power, the FPGA retains the hardware configuration file in the flash memory. When
