【AM5728 OpenCL】AM5728的OpenCL和OpenCV例子运行错误

运行所有的OpenCL例子的时候出现了如下的错误：

TIOCL FATAL: OpenCL needs 1 CMEM blocks to operate – one each for off-chip (DDR) and on-chip (MSMC SRAM or OCMC RAM) memory

求指点迷津！！！

Jian Zhou：

你是在TI的AM5728 demo板上测试的么？

linux-4.4.19版本内核

我使用的是J6，也出现了这个问题，求解答

回复 Jian Zhou:

在使用J6上编译的opencv库，然后用了cv::cvtColor(color, bgr, CV_GRAY2BGR);这个函数就会出现上面的问题

J6是啥/?
