I am using the SDMMC1 interface without an SD card, utilizing only the data lines. Therefore, the CMD line is not needed, and I have deactivated the CMD pin. However, the HAL_SDMMC library sends CMD data and expects a response from the SD card, causi...
HelloI wrote the following code to activate the display.The code below is written in kernel/stm32mp157a*.dts and u-boot/stm32mp157a*.dts.panel_rgb: panel-rgb { compatible = "panel-dpi"; label = "lcd"; power-supply = <&vdd_panel>; status =...
Hello all,The startup of the M4 core is easy enough, echoing "start" to the state enables the core.Shutdown is also simple, echoing "stop" to halt the coprocessor. However on shutdown, peripherals such as the PWM sometimes end in a high state. For my...
Hello, I am in the process of planning and testing the STM32mp13 Line.We have equipped our project board with the STM32mp13 CPU, but we encountered an issue when trying to connect it via St-link; it did not establish a connection.The St-Link version...
I downloaded the STM32MP151AAC3 example model (.zip file) that routes traces to the DDR3L memorySTM32MP151A - MPU with Arm Cortex-A7 650 MHz, Arm Cortex-M4 real-time coprocessor, TFT display - STMicroelectronics Then I measured DDR_Q1 to DDR_7, DQM0,...
Hi!I noticed this.The FC-135 32.768 kHz crystall with CL = 12.5 pF, ESR max = 70 kOhm and C0 = 1.0 pF is suitable for MP1 products.The gmcrit is 2.1631 uA/V.When I do the math, i found out that gain margin is below 5.C0 = 1.0*10^-12;CL = 12.5*10^-12;...
Hi there, I'm trying to configure a CubeMX project, starting from scratch, for a custom board based on a STM32MP153CAC3. And I'm having an issue with the MPU clock setting. In particular, I can't select any MPU Clock Mux option and see the PLL1 tree ...
Hi!I was recommended to use the pre-built basic start-up projects for the STM32MP series, instead of buildning my own from scratch.Solved: Re: Why are the DDR_DQ signals mixed in unsorted o... - STMicroelectronics CommunityThe project files are Altiu...
I am trying to build a custom board for the stm32mp151A using the STM32MP15 Evaluation boards as a reference.U-BOOT starts, but the kernel won't start, and I'm at my wit's end.1. When the device starts up, the console displays "CPU: STM32MP151AAC Rev...
