Hi, I've been pointed out to STM32 to get a low latency HDMI input (splitted) receiver that can render the input into a video stream and process a neural network on it before sending the computed processed outcome (python or similiar) to another hard...
Hello everyone, I would like to connect the stm32mp157c-dk2 card with the wm8960 audio codec,here is the device tree configuration I made./* sound card*/ snd_i2s2: snd_i2s2 { compatible = "audio-graph-card"; widgets = ...
I have an STM32MP1-DK2 and have tried to install pip using several python mechanisms, but there are missing modules. The notable ones that I found missing are runpy and xmlrpc. Even when I go into python and type help() it spits out an error about py...
hi,i updated STM32CubeIDEto Version: 1.4.2Build: 7643_20200813_1322 (UTC)and now the debug session doesn't send the compiled firmware to the target and just starts the gdb connection :Open On-Chip Debugger 0.10.0+dev-g30d1303 (2020-06-18-09:13)Licens...
Hello,I have been trying to work with the BSEC and write some data to the upper OTPs, where I managed to successfully write only to the words containing the MAC address. Then I realised, that the device tree needs to be modified to allow other OTP wo...
Hi,I want to update the boot chain (basic mode) for a "custom" device tree.Following the wiki page below, I understood how to update the boot chain (trusted mode) for a "custom" device tree.https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_devi...
Hello Everyone.I am using stm32mp157c DK2 and EV1 for my project.I thought that the board suitable for my project purpose is DK2 for the following reasons, and EMMC is required in addition to this.In the current DK2 configuration, removing HDMI, DSI ...
Hi,I'm using Avenger96 Board using Build-Sytem through Yocto.I want to increase Rootfs Partition Size to 2Gb.Changes done so far:1)Edited /meta-st/meta-st-stm32mp/conf/machine/include/st-machine-common-stm32mp.inc--ROOTFS_PARTITION_SIZE = "2097152" -...
I am designing a board using STM32MP1, STPMIC1A and LPDDR2. I want to use 3.3V VDD not 1.8V as most of peripherals are 3.3V. I am following example in AN5031 Figure 32 LPDDR2 VDD1 is powered from LDO3 in bypass mode which is powered by VDD 1.8V. I pl...
