hi experts i am not sure this is a right place to use and not good at English please be generousi am not good at linux , i read a wiki "STM32MP15 RAM mapping" and googled some informationi use kernel and u-boot from developerPackagei have no pl...
Hi there, I am working on an OSD32MP157F custom board inspired by STM32MP157F-DK and Octavo Red boards. The pinout is very similar to the stm32mp157f-dk with the main difference that the Murata LBEE5kL1BX-883 is connected to sdmmc3 instead of sdmmc2 ...
Hi, we need a buffer about 200KB on CM4 MCU (STM32MP153)We change the linker file as below, that allow 256KB heap (combine SRAM2 and SRAM3)But every time the buffer has more than 0x30000 (192KB) then it is failed, seem we can't combine SRAM2 and SRAM...
I would like to use the Murata Wi-Fi/BT combo module 2BC on STM32MP1.Is it possible?If it is possible, I would like to know how to integrate 2BC on STM32MP1. I understand following.- Murata 1DX are mounted on STM32MP1 evaluation board.- Murata has th...
Hello!I have a MP1 board (STM32MP157), and i was wondering if one can have control over which individual pins are used when it comes to FMC. I want to use FMC for PSRAM, 8-bit data mode, but the pin that corresponds to FMC_A2 is already in use (PF2),...
Hi ST Community,I am trying to flash a eMMC with STM32CubeProgrammer, in a STM32MP157F custom board. I am using a GPT partition file and a img.I can see the system is creating partitions and flashing, but the structure is wrong for eMMC, so it does n...
I have a board where a secondary CPU can select the STM32MP1's boot mode. On initial boot, the MP1 boots from NOR flash. I can then send a command to the secondary CPU which switches the MP1's BOOTx pins to enable engineering boot and resets the MP...
Recently for a design I had used STM32 MPU (part# "STM32MP157FAA1") with DDR3L (part# "NT5CC256M16ER-EK"). For simulating data & address lines from the IBIS model "ibis5_4gbddr3_e_1p35_0c~95c.ibs" in ANSYS for 500MHz frequency the source transmitter ...
Hi there, I am developing on an STM32MP157. We are trying to add two Linux virtual network interfaces that specify a VLAN ID using networkd. Specifically, we specify IDs 20 and 30. We do not specify VLAN ID 0. On boot, networkd successfully creates t...
I have a stm32mp135f board (I'm mainly interested in Linux capable SoC) and I am trying to learn something about trusted firmware a, optee, and secure boot solutions. Although the documentation is pretty decent I don't see how I could test the whole ...
