内存加大,导致sample_venc_rtsp 运行报错

修改如下2个文件内容
smp/a7_linux/source/bsp/tools/pc/uboot_env/env_text/hi3516cv610/nand_env.txt
bootargs=mem=32m console=ttyAMA0,115200 clk_ignore_unused root=ubi0:ubifs rootfstype=ubifs rw ubi.mtd=3 mtdparts=nand:512K(boot),512K(env),4M(kernel),32M(rootfs)
改成

运行sample venc rtsp出现
open sys: No such file or directory
open err
:No such file or directory
open err
:No such file or directory
[sample comm sys init with vb supplement]-288: hi mpi vb set conf failed!
[sample venc sys init]-407:sample venc sys init failed!
[sample venc noral]-734: Init sYS err for 0xffffffff!
program exit abnormally!

这个分析是mmz设置的问题，看不出设置的问题
