Ask questions and find answers on STM32 microprocessors, including hardware, power, DRAM, flashing, interfacing, device tree, and peripherals.
I found the pin of PG8 on the GPIO pin map on the board. So I connected to PG8 and GND to connect with oscilloscope.In the picture, the blue line is the oscilloscope's GND port.I connected the board and the oscilloscope like the picture above. And I ...
Our product has a STM23MP151D, no security features (signed stuff or fuses blown) and the same QSPI NOR as the EV1 board.We have run the microcontroller style DDR tester (STM32DDRFW-UTIL) which took a bit of bashing to run on the 151 but did show our...
Is possible to install ppp tools to connect internet using a GPRS modem ?We need pppd/chat and kernel support to get network interface, but I can't found them on OpenStLinux resources.
I am using DP83848 PHY RMII interface and 50MHz external oscillator and PA1 as ETH_RMII_REF_CLCK pin. I ignored 125MHz input pin.But when active ethernet, I see a problem similar to Stm32mp157 Ethernet problem, saying that there is no input clock.I c...
Hello, Using the stock image I've found I can manipulate the red LED on PA13 by using gpio commands:gpioset gpiochip0 13=0 gpioset gpiochip0 13=1I need to access Pin 38 and Pin 40 on the 40 pin header, which are PI6 and PF11.These are both tied to th...
Hi, we would like to change from 24MHz to 8MHz which is available in our stock, I see in device tree, file stm32mp151.dtsiclocks { clk_hse: clk-hse { #clock-cells = <0>; compatible = "fixed-clock"; clock-frequency = <24000000>; }; ...
I am trying to use the 40 pin GPIO, namely pin 48 and pin 40 which are PF11 and PI6. PI6 is assigned to sai2. I've disabled sai2. However, the DTB will not compile because there is still a reference to the sai2 pins here:sound:sound{ compatible = ...
Hello, I bought STM32MP157D-DK1 design kit. But I would like to buy the display board from ST. is it possible?Because I only saw that if you buy the STM32MP157F version.Many thanks,Mauricio
We modified the device tree file corresponding to our development board based on stm32mp157d-ev1.dts.We did not use a PMIC chip, so we added our own power node and modified the default serial port output.This is my device tree file:The following erro...
