cudaMemcpy(&worker1_d, worker1, 512*sizeof(unsigned char), cudaMemcpyHostToDevice);
Hi I have an unsigned char array that is added to worker1 using the simple for loop above, I then want to copy worker1 to worker1_d for cuda processing but the cudaMemcpy is causing an error, I have re-wrote it many times but cant get the syntax right.
any idea’s appreciated.
