hi_vpss_chn_attr：定义 VPSS 物理通道属性。depth 用户获取通道图像的队列长度。取值范围：[0, 8] sample_venc_vpss_init是否需要设置depth?还是保持默认值0？

Hi,各位好，编译SDK的watch dog出现如下error，请问是何原因呢？/drv/interdrv/wtdg$ make—Compiling ‘hi3531dv200_wdt’… Configs as follow:—— CROSS=aarch64-himix200-linux-—— HIARCH=hi3531dv200, HICHIP=0x3531d200, CVER=.C02, DBG=, HI_FPGA=HI_XXXX—— CPU_TYPE=a53—— MPP_CFLAGS=-Wall -DHI_RELEASE -Wno-error=implicit-function-declaration -DVER_X=1 -DVER_Y=0 -DVER_Z=0 -DVER_P=0 -DVER_B=10 -DUSER_BIT_64 -DKERNEL_BIT_64 -Wno-date-time—— SDK_PATH=/home/xia/work/SDK_3531DV200/Hi3531DV200R001C02SPC003/01.software/board/Hi3531DV200_SDK_V2.0.0.3/drv/interdrv/wtdg/../../../mpp/.. , PARAM_FILE=../../../mpp/Makefile.param—— KERNEL_ROOT=/home/xia/work/SDK_3531DV200/Hi3531DV200R001C02SPC003/01.software/board/Hi3531DV200_SDK_V2.0.0.3/drv/interdrv/wtdg/../../../mpp/../osdrv/opensource/kernel/linux-4.19.y—— ARCH_ROOT=, ARCH_HAL= make[1]: Entering directory ‘/home/xia/work/SDK_3531DV200/Hi3531DV200R001C02SPC003/01.software/board/Hi3531DV200_SDK_V2.0.0.3/osdrv/opensource/kernel/linux-4.19.y’arch/arm64/Makefile:28: ld does not support —fix-cortex-a53-843419; kernel may be susceptible to erratumarch/arm64/Makefile:49: Detected assembler with broken .inst; disassembly will be unreliablearm-none-eabi-gcc: error trying to exec ‘cc1’: execvp: No such file or directoryarm-none-eabi-gcc: error trying to exec ‘cc1’: execvp: No such file or directory CC [M] /home/xia/work/SDK_3531DV200/Hi3531DV200R001C02SPC003/01.software/board/Hi3531DV200_SDK_V2.0.0.3/drv/interdrv/wtdg/hi_wtdg.o

请问谁有：Download trusted-firmware-a-2.0.tar.gz from https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/ before compiling the busybox.这个网址一直访问不了，其他出收索，出来的都是arm-trusted-firmware-2.0.tar.gz似乎跟SDK要求的不一样还请赐教

Hi，目前在做一个调研，Hi3559A,是否支持同时输入4路视频?如HDMI X 2（1080p@60） + SDI X 2(1280x720@50)，用对应Rx接收芯片转成bt1120
