I'm testing STM32MP157A for our new projects. The MPU VCC is 1V8, USB is 3V3. Debugger is connected to two SWD pins. One of first test is:boot into DFU loader, upload simple code to 0x2ffc2500:S_GPIO_ALT(GPIOA,13,2); S_GPIO_ALT(GPIOA,14,2); RCC->MCO1...
HiI plan to interface the MT9M001 CMOS sensor (Parallel Interface) with STM32MP135F-DK, but the development board comes with the MIPI CSI2 Interface. Please guide me as to the process of integration and using OpenCv. Thanks
We are using STM32MP!57A processor in our custom board. In this we are unable to read the internal ADC values in our cards. Actually, we initialize the internal ADC pins in cortex-M4 core with support of STM32CUBEMX and debug in CubeIDE...
Hello everybody,I am developing a custom board strongly inspired by the STM32MP157D-DK1, except that I use a parallel DPI RGB on 24bit display.I use openstlinux-6.1-yocto-mickledore-mpu-v24.06.26.The frequency of "LTDC_CLK" changes by itself after wa...
Hi,I tried to update the DTS to make use of the adapter but unfortunately without success. These are the change I made:hdmi-out { compatible = "hdmi-connector"; type = "a"; port { hdmi_con: endpoint { remote-end...
Hello,I have a STM32MP2 platform with A/B partitioning for TF-A, metadata and FIP.I'm looking for a way to generate a test FIP and install it in FIP-B bank, have TF-A load it, if this FIP contains a bad signature or other error that will prevent Uboo...
Dear,I'm starting with OP-TEE on STM32MP15x line. I bring-up the board as described here and built the optee_example_hello_world as described here. However, I got the error code below:TEEC_Opensession failed with code 0xffff0008 origin 0x3Checking th...
Hello,I am trying to generate output with adjustable pulse width using One Pulse mode.The output pin is in a Pull-Up state, with an initial state of High. When One Pulse mode is activated, it outputs a Low signal for the specified duration.However, t...
Even if I route the differential pairs, one pair will always be longer than the other.Should I route an extra path, like a sawtooth or tromebone on the shortest pair to make booth differential pair equal in length?I see that the STM32MP1 dev-kit does...
I created a st-image-qt image using the STM32MP Distribution package and X-LINUX-QT add-on for the STM32MP157F-DK2 board.I could flash this image using the dd command in Linux and my target board is running correctly.On the other side, I created a qt...
