TDA4VM: TDA4VM

请问是自己的板子还是TI的EVM板？能否发一下执行步骤和执行后的log信息？

您好，我这边使用的是TI的EVM板，型号为J784S4XG01EVM，我的执行步骤如下：

1. 准备好SDK 8.2和SDK 8.6的人脸关键点检测模型（PFLD）的bin文件和运行的cfg文件，bin文件为tidl_io_pfld_1.bin和tidl_net_pfld.bin，cfg文件为app_my.cfg，我已经上传到Google Drive里面了，分享链接如下

SDK 8.2 : https://drive.google.com/file/d/1ZSKoRsou3eC7-526ZADT2MKcRb0XOaIY/view?usp=drive_link

SDK 8.6 : https://drive.google.com/file/d/1mAoLMCnnGSjdvKkEUfxBxur28pCd6ny4/view?usp=drive_link

2. 修改vision_apps/kernels/img_proc/c66/vx_draw_box_detections_target.c为下面内容

3. 编译SDK

4. 我这边采用的例程是vision_apps/dl_demos/app_tidl_od，生成的可执行文件为vx_app_tidl_od.out，在EVM板上运行vx_app_tidl_od.out --cfg app_my.cfg

5. 在SDK 8.2 上得到的LOG信息如下，此时程序卡死，

屏幕上面显示的效果如下
