GZip : Segfault when no awsxclbin or xclbin is present
It makes sense that the execution does not work when no AWSXCLBIN nor XCLBIN is found, but, in my case, this situation causes a segfault on the call to cl::Program
, which is difficult to diagnose.
Maybe find_binary_file
in xcl2.cpp
should at least specify whether we found an .awsxclbin, an .xclbin, or neither and at least warn that finding neither may cause errors?
HW run fails on 326MB compress
Testing this code I tried to feed the generated SDAccel_Kernel.tar file into the app and it generates an error
./xil_gzip -i Developer_SDAccel_Kernel.tar
result:
ERROR: Failed to sync 652124160/-5 bytes
terminate called after throwing an instance of 'xrt::error'
what(): event 3 never submitted
Aborted
Is the sample code constrained in max size?
WebP & fpga dev ami version
is WebP buildable with any of the current (1.4.0+) fpga developer ami's?
More Information
Do you have more information on the compression ratio?
SDaccel segfault when executing GZip from Xilinx Applications (HW emulation)
Hello everyone,
I am trying to build the GZip example from Xilinx Applications
I was able to successfuly generate the awsxclbin following these steps but I encountered an issue.
My executable will only work one out of several trials resulting in a segfault when failing with output:
root:/home/centos/Git/Applications/GZip# ./xil_gzip -i xocc_gZip_app.hw.xilinx_aws-vu9p-f1-04261818_dynamic_5_0.log
xclProbe found 1 FPGA slots with xocl driver running

Segmentation fault
I used gdb to debug it and found where the segmentation fault was coming from:
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff6697511 in xocl::device::allocate_buffer_object(xocl::memory*) () from /opt/xilinx/xrt/lib/libxilinxopencl.so
I am kind of lost as to why this would be happening.
Does anyone have an idea ?
I am using an f1.2xlarge instance from aws.
Best regards.
LZ4: where can I find the top-level project file?
Hi,
I'm using the LZ4 compression core for my custom logic.
However, after running the bitstream generation with tcl, it is hard to reconfigure the ports due to the unclear Verilog code generated from the high-level synthesis.
So, I want to open the project file right before the bitstream generation and add my code.
Is there any other way to add my code and generate the bitstream file?
Thanks in advance.
Best regards,
vitis
well, i am using vitis running a networking example,and there shows error below
Makefile:158: /home/fyf/Desktop/common/includes/opencl/opencl.mk: No such file or directory
Makefile:159: /home/fyf/Desktop/common/includes/xcl2/xcl2.mk: No such file or directory
can i use the code in this repository to solve it?
Cannot find the correct device in emulation mode using JNI
I have already mentioned the issue in the xilinx community, please refer to this link:
https://forums.xilinx.com/t5/SDAccel/Cannot-find-the-correct-device-in-emulation-mode-using-JNI/m-p/885044/highlight/true#M2423
@heeran-xilinx @fengx-xilinx Can you help me solve this issue? Thanks in advance.
Best Regards.

WebP: Make flow is broken, too many Xilinx internal path references
The compilation scripts for WebP (xocc.sh, Makefile.xocc) reference a lot of Xilinx internal paths. In their current states, the scripts are unusable and require significant modification on the user-side just to get this app up-and-running. Users of your WebP accelerator would greatly appreciate if you could update the scripts and remove the internal references. Thank you!
