cudaMemcpy - 收到错误：cudaErrorInvalidValue 11

Question

这是我的代码：

unsigned char *d_eCB[9];
unsigned char eCB[9] = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };
err = cudaMalloc((void **)&d_eCB,9*sizeof(unsigned char));
err = cudaMemcpy(d_eCB, eCB, 9*sizeof(unsigned char), cudaMemcpyHostToDevice);

错误发生在以下行：

err = cudaMemcpy(d_eCB, eCB, 9*sizeof(unsigned char), cudaMemcpyHostToDevice);

错误如下：cudaErrorInvalidValue 11

Answer 1

我改变了

unsigned char *d_eCB[9];

到

unsigned char *d_eCB;

谢谢。
