[参考译文] TDA4VEN-Q1：在 TDA4VEN SDK11.01 中使用 OpenCL 调用 GPU 时发生错误

我的 TDA4VEN-Q1 电路板上的 HLOS 是 Linux  （具体包括 TDA4VEN SDK 11.01 的 Yocto Linux 版本）。 根据您的建议、我们已经尝试了这些步骤：

  1.在运行我的应用程序之前:

pvrdebug -loggroups main,mts,hwr

      这些命令的控制台输出如下所示：

root@spartan_a:/# cd data/270test/
root@spartan_a:/data/270test# pvrdebug -loggroups main,mts,hwr
----------------------- Start -----------------------
Set FW Log type to TRACE ( main mts hwr )
Connecting to first (0) default pvr device
------------------------ End ------------------------

     此日志中的错误不是由 tiovx 导致的、而是因为内核代码调用行“clGetPlatformIDs (0、NULL、&num_platforms“）“。 这行代码旨在检索 CL 的执行平台 (GPU)。由于未找到执行平台、因此它会在/data01/shijuechuangan/tda4/PSDK0703_ISP/Workspace/tianlib/tda4_traton/vision_apps/kernels/270 缝线/mpu_0/avm_app_demo_cl.c：29“中报告“OpenCL 错误–1001。

  2. 执行过程中遇到 OpenCL/GPU 错误后,我运行:

pvrlogdump

pvrlogdump 的控制台输出如下：

这可能是由于电路板图像中没有 GPU 驱动程序造成的、还是有其他可能的原因？
