When running my design in SDAccel, I see the following errors:
In 2018.3 and prior releases, if the buffer could not be allocated on the designated bank, XRT would try to allocate a random buffer for the application.
Starting in 2019.1, if the buffer cannot be allocated on the designated bank, it will return an error. If the xclbin does not contain proper connectivity information, then some applications might fail.
Please check kernel connections to global memory in the .xclbin and modify the host code to use clSetKernelArg before any enqueue operation on the buffer.
