STM32 MPUs Products and hardware related

Good afternoon! I'm trying to use TSC2046 based touchscreen device on a STM32MP157C-DK2 based custom board. I get SPI transfer time-out when touching the screen. Does anyone have a similar problem ?

I'm using spi5 and my device tree settings are &spi5 { pinctrl-names = "default", "sleep"; pinctrl-0 = <&spi5_pins_a>; pinctrl-1 = <&spi5_sleep_pins_a>;    #address-cells = <1>;    #size-cells = <0>; num-cs = <1>; is-decoded-cs = <0>; cs-gpios = <&gp...

Level of Support for custom Operating System?

Hello,I'm writing to inquire if there is documentation/support for developing non-linux operating systems using the STM32 MPU discovery kits. So far I've only found Cube support and documentation for ST's custom linux distro. Obviously, a processor b...

The RGMII specification specifies a rise time of 0.75ns max. Looking at the STM32MP151A datasheet I can't select a speed setting to match this specification, they are all to slow. In the AN5031 a "High speed" selection is recommended. Do I miss something?

How to enable PWR_USB_SW in STPMIC?

Hello,I am working on a custom board based on stm32mp157 and I have the need to enable the PWR_USB_SW through the ST PMIC. So far, I identified the bit VBUSOTG_ON in register BST_SW_CR (0x40) but I had no success in configuring it via devicetree or v...

when i use STMCubeMX(version6.8.0) to generate the code about STM32MP157DAA1,i find whether i define the GPIO's user label,it just can't generate in the keil project.

i also find some people say this is a bug,repeatedly click the setting of user label can be solved,but i try it's can‘t figure it out.....By the way,GPT also not give the correct solution (this is why i am here)​this is my first question in this com...

OpenAMP_TTY_echo_wakeup can't manage to wakeup M4

Hi there, I'm developing on a STM32MP157 custom board. I'm trying to work with power modes, and I tried to import the OpenAMP_TTY_echo_wakeup example inside our M4 firmware. I already had the IPCC module set up and I use virtUart periperal without an...

How to make TFA redundant and how to make ROM code select different partitions of FSBL?

In stm32mp157, I need two partitions for FSBL, and it is working correctly, but I want to make TFA redundant meaning I should be able to update the second partition of FSBL and then shift it on the second partition on restart.I have made roofs redund...

Using sftp client on STM32MP1 Linux

I am having trouble how to setup the Linux system on the STM32MP1 so that I can use sftp to upload data gathered by the device to an external server.What happens is that once the connection is established it immediately closes again, so there is no t...
