Description
Hi all,
I am currently trying to add some HLS IP on kv260 with 2022.1 tool chain.
I have tried the basic vadd example, it could run properly on zcu104.
But with the same work flow on kv260 is not working with the same example code.
# ./vadd /lib/firmware/xilinx/app-vadd/app-vadd.xclbin
INFO: Reading ./app-vadd/app-vadd.xclbin
Loading: './app-vadd/app-vadd.xclbin'
Trying to program device[0]: edge
Device[0]: program successful!
Segmentation fault
The info of xrt & zocl from xbutil seems to be the same between zcu104 & kv260.
# xbutil examine

By comparing the difference between xclbin
I find out :
- The
xclbin
of kv260 is missing sectionCONNECTIVITY
&GROUP_CONNECTIVITY
.
- The
Address Size
inMemory Configuration
of thexclbin
for kv260 is all0x0
.
- The
Memory
inInstance
of thexclbin
for kv260 is allnot applicable
.
Is the failure of vadd example code caused by these reason?
Or there is something I have missed?
By the way I have also verify the function with a simple xrt code which works on zcu104 but out_of_range
on kv260.
