Hello. We have IMX8MP HummingBoard Pulse kit, and downloaded latest Yocto imagies from GitHub. Prob both Zeus and Gategarth. The kit does not play video. Gstreamer cant use VPU. Atached the log file. It seems that the same problem was on NXP forum. and The solution was: > Yes with official bsp it is working. My issue come from my integration in my yocto env. > > I found the issue and for other user I will try explain my issue. > 1 - What was my problem : > VPUdec gstreamer module failed to malloc memory > 2 - My fix : > I must to synchronised all these recipes to same bsp version (me i synchronized with warrior version) > linux-imx > inux-imx-headers > imx-vpuwrap > imx-vpu-hantro > > And in [conf/machine/include/imx-base.inc](https://gerrit.oplv-france.pro/c/opensource/yocto-meta/freescale/+/50920/3/conf/machine/include/imx-base.inc)check var MACHINEOVERRIDES\_EXTENDER\_mx8mq, imxvpuhantro should be inside it. > > 3 - Why I met these issues > > My yocto env was created for raspberry board, and more later I had support for nxp board. > My reference was poky version thud. But I met an issue with nxp tee with this version so I upgrade kernel, optee-os, optee-client to warrior version for fixed it. > linux-imx and inux-imx-headers was not more synchronised and vpu didnt work anymore What does it means? I am new to linux and Yocto, what should i do? How to fix images of Yocto? the full log-\>U-Boot SPL 2020.04-5.4.70-2.3.0+gdb466e3f9b (Apr 01 2021 - 12:27:02 +0000) Training for 3GByte Micron DDRINFO: start DRAM init DDRINFO: DRAM rate 3000MTS Training FAILED Re-training for 1GByte Samsung memory DDRINFO: start DRAM init DDRINFO: DRAM rate 4000MTS DDRINFO:ddrphy calibration done DDRINFO: ddrmix config done Normal Boot Trying to boot from BOOTROM image offset 0x8000, pagesize 0x200, ivt offset 0x0 NOTICE: BL31: v2.2(release):rel\_imx\_5.4.70\_2.3.0-0-gf1d7187f2 NOTICE: BL31: Built : 12:26:03, Apr 1 2021 U-Boot 2020.04-5.4.70-2.3.0+gdb466e3f9b (Apr 01 2021 - 12:27:02 +0000) CPU: i.MX8MP[8] rev1.1 1800 MHz (running at 1200 MHz) CPU: Commercial temperature grade (0C to 95C) at 33C Reset cause: POR Model: NXP i.MX8MPlus LPDDR4 SolidRun board DRAM: 992 MiB MMC: FSL\_SDHC: 1, FSL\_SDHC: 2 Loading Environment from MMC… \*\*\* Warning - bad CRC, using default environment [\*]-Video Link 0probe video device failed, ret -2 ``` [0] lcd-controller@32e80000, video [1] mipi_dsi@32e60000, video_bridge [2] adv7535@39, panel ``` probe video device failed, ret -2 In: serial Out: serial Err: serial BuildInfo: - ATF f1d7187 - U-Boot 2020.04-5.4.70-2.3.0+gdb466e3f9b switch to partitions #0, OK mmc1 is current device flash target is MMC:1 Net: Warning: ethernet@30bf0000 (eth1) using random MAC address - b6:4b:26:51:24:b5 eth1: ethernet@30bf0000 [PRIME] Fastboot: Normal Normal Boot Hit any key to stop autoboot: 0 switch to partitions #0, OK mmc1 is current device Scanning mmc 1:1… Found /extlinux/extlinux.conf Retrieving file: /extlinux/extlinux.conf 218 bytes read in 15 ms (13.7 KiB/s) 1: NXP i.MX Release Distro Retrieving file: /extlinux/../Image 28078592 bytes read in 1206 ms (22.2 MiB/s) append: root=/dev/mmcblk1p2 rootwait rw console=ttymxc1,115200,115200 Retrieving file: /extlinux/../imx8mp-hummingboard-pulse.dtb 57894 bytes read in 20 ms (2.8 MiB/s) ## Flattened Device Tree blob at 43000000 Booting using the fdt blob at 0x43000000 Using Device Tree in place at 0000000043000000, end 0000000043011225 probe video device failed, ret -2 Starting kernel … [0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd034] [0.000000] Linux version 5.4.70-2.3.0+g1658dcd44915 (oe-user@oe-host) (gcc version 9.2.0 (GCC)) #1 SMP PREEMPT 1 [0.000000] Machine model: NXP i.MX8MPlus SolidRun board [0.000000] efi: Getting EFI parameters from FDT: [0.000000] efi: UEFI not found.

Can you provide information regarding the video you are trying to decode? The iMX8MP only supports decoding video up to 1080p60 H264 or HEVC. If you are trying to decode a video larger than that then the pipeline will fail with an out of memory error. ---
