STM32 MPUs

In AN5031 Rev4,Figure 49. Gigabit Ethernet 2-port switch example with VDD = 3.3 V (RTL8363NB-VG)There is the RTL8363NB used, but I can't find the driver anywhere.Can you provide the driver file or tell me where it is?

Hello!I am trying to replicate the workshop STM32MP1 - 11 Inter-Processor Communication Lab Example. I create a new STM32 project and copy all the data from the lab example. Then I connect the device (STM32MP157C-DK2) but the /dev/ttyRPMSG0 does not initialize (so I can´t send message between processors):My programSTM32MP1 - 11 Inter-Processor Communication Lab Example I create my program in STM32CubeIDE version 1.10.1.How can I initilize ttyRPMSG0 and ttyRPMSG1?Thanks!

We quite recently learnt of the move from U-Boot SPL to STM32DDRFW-UTIL and that the MX too would not longer work with the former. That wasted a decent amount of time.The problem is although the code for STM32DDRFW-UTIL is available our PMIC is on I2C6 and the code for the DK2 board doesn't abstract the connection of its PMIC to I2C4 cleanly.For example there's a function called BSP_I2C4_WriteReg that calls I2C4_WriteReg. Elsewhere it says#define DISCO_I2C4_CLK_DISABLE() __HAL_RCC_I2C4_CLK_DISABLE()and there are a load more defines that DISCO_I2C4 is I2C4_something. I feel a lot more of this could have been done making better use of pre-processing to reduce the repetition of things of the form#define <w>_I2C<n>_<x> <y>_I2C<n>_<z> .It should be that the disco's STPMU1_Register_Write calls I2C4_WriteReg and that's the board abstraction.Is there a guide to the simplest way to change the I2C port the PMIC is connected to in STM32DDRFW-UTIL ?Thanks,Jon

We are trying to read an analog value from a sensor (PF14 pin - A0 on Arduino connectors) and send it over UART (UART7 - PE7 for RX, PE8 for TX) for reading in the terminal of computer. We use M4 for this aim. Our final goal is to read the analog value over OPENAMP to be used on A7 side. But we want to be sure about the data integrity, and correctness of analog output as a first step. That's why we use UART7 through FTDI. We can read only "enclosed question marks" in the terminal. We are able to correctly read and graph analog readings with NUCLEO-STM32L432KC, using the same sampling rate and using USART1 and FTDI (although data resolution seems to be decreased significantly, compared to reading data over ST-LINK). Since ST-LINK is dedicated to A7 in STM32MP157F-DK2, it seems that it can not be used on M4 side (in Engineering Mode) for our aim.The pin configuration in A7 dts file is as follows.m4_uart7_pins_mx: m4_uart7_mx-0 {   pins {      

In engineering mode (BOOT0:off, BOOT2:On) I want to update my cortex-m4 firmware from CMD, not an IDE. What is the command to do so?Thank you!Note: I tried using the STM32_Programmer_CLI executable but it keeps seeing the a7 only, I cant communicate with the m4.Note: I think the IDE uses OpenOCD to do so but I can't find how to extract the command line it uses.

Next problem with my board is the RS485. I can send bytes, but can't receive because after sending once the DE stays always high. Without sending receive of course works.&uart5 { status = "okay"; pinctrl-names = "default", "sleep","idle"; pinctrl-0 = <&uart5_pins_a>; pinctrl-1 = <&uart5_sleep_pins_a>; pinctrl-2 = <&uart5_idle_pins_a>;   rts-gpios = <&gpioc 6 GPIO_ACTIVE_HIGH>; rs485-rts-delay = <0 0>; linux,rs485-enabled-at-boot-time; };uart5_pins_a: uart5-0 { pins1 { pinmux = <STM32_PINMUX('B', 6, AF12)>; /* UART5_TX */ bias-disable; drive-push-pull; slew-rate = <0>; }; pins2 { pinmux = <STM32_PINMUX('B', 5, AF12)>; /* UART5_RX */ bias-pull-up; }; };   uart5_idle_pins_a: uart5-idle-0 { pins1 { pinmux = <STM32_PINMUX('B', 6, ANALOG)>; /* UART5_TX */ }; pins2 { pinmux = <STM32_PINMUX('B', 5, AF8)>; /* UART5_RX */ bias-pull-up; }; };   uart5_sleep_pins_a: uart5-slee

Hi i want to access remotely my stm32mp157c-dk2 with graphical interface. I am running openstlinux-20-02-19 from starter package. I installed tigervnc (apt-get install tigervnc and apt-get install xauth) and start it by typing "vncserver". But when i connect to it (from vncviewer) only terminal shows up, nothing else. I tried to start some desktop session from this terminal by typing (weston / weston-start / dbus-launch weston-start / weston-launch) but nothing works. I also tried to modify ~/.vnc/xstartup and changed to :#!/bin/shunset SESSION_MANAGERunset DBUS_SESSION_BUS_ADDRESSexec dbus-launch weston-startBut after this change, only black screen shows up : /I am new to wayland/weston and vnc configuration. I hope somebody with more experience can help me with this.

Hello!I am trying to replicate the workshop STM32MP1 - 11 Inter-Processor Communication Lab Example. I create a new STM32 project and copy all the data from the lab example. Then I connect the device (STM32MP157C-DK2) in production mode to send message between processor but the following message appears in the terminal:/dev/ttyRPMSG0: no such file or directory Can somebody help me?Thanks!

Hello,I have a STM32MP157F-DK2 and I'm planning to develop some python applications to run on the A7 processor. I have some questions related to python development for this platform, as I have not found too much documentations regarding this:Software package: Which ST software package do you recommend for python dev? Given that I will not need to cross-compile any C/C++ application with an SDK, can I use the Starter package, or do I need to use the dev package?Will the default starter of dev packages contain the python modules that I will need to connect and read data from Bluetooth devices?Will the default starter of dev packages contain the python modules that I will need to create GUIs for the TFT display?If I need to install a python module that is not present by default on the image, can I do it at run time, or do I need to create a custom distribution package? how?If you have any examples or tutorials for python development for the STM32 they are very welcome.

Hi, I'm trying to leverage the capability of lower words to be programmed once to one bit by bit to implement a sort of "forever growing counter", not sure if there is a proper naming for this.In the lower OTP zone, if I understood correctly, word 10 and word 11 are for OEM, does that mean that they are totally free to be used?Best regards,Charles

I have problem to get USB to work. I'm using custom board but I know that USB works because if I boot the board with the delivered image (MyIR) the USB works. I'm using buildroot with the 5.10 kernel and the linux kernel configuration from bootlin git.

I would like to clear up some confusion regarding the DSI VIO, the stm32mp157a datasheet mentions "1.2 V I/O for DSI interface" but in the EV1 kit the LCD used (the RK055AHD042-CT, for which it's impossible to find a datasheet for, could that be shared too?) uses the RM68200 driver which seems to require 1.8V for IO.The LCD I would like to use also requires 1.8V so I'm wondering if I need a high-speed voltage translator or will the STM32MP1 support my LCD?

I just spent a day trying to configure a gpio with internal pullup using gpiolib. Could not get it configured. Then spent 2 days with device drivers and device trees, and got it working. Seems insane to me that configuring gpios should be this complex. Is there an easier way?

Hi I am working on a drivers for the various peripherals on the STM32. Let me take the GPIO as an example. GPIO BSRR is a write only register that I want to read and I need to read back always 0x00000000. Why?I made a bit-field struct on the whole GPIO block. That struct is accessed based on Register name and specific bit field. The processor can not operate on individual bits so the compiler translates the Bit field instruction in to a register read followed by mask and shift operations ending with a Register write. It's the compiler that manipulates individual bits in a register in this way.So the value of the write only register like a BSRR when it is read is important and needs to be 0x00000000 for a bit set operation.Here is my question, is the read back of a write only register like the BSRR well-defined in the design of the STM32 chip or is that value undefined.Question:Can someone tell me if the read back of Write only registers is well-defined as 0x0000000 for the STM32 family
