Hi. I am using the Uart Bootloader from the ROM.I want to write my Programm to the Sysram at 0x2FFC3000. I don't know why, but the Software ignores my commands.It accepts the write Command, it accepts the adress. But when i write the Address it twic...
I've spent some time looking over the STM32MP15x hardware manual but cannot confirm that the FMC levels (in SRAM mode) are 1.8v. Can this be confirmed or corrected please?
I'm trying to develop an application that puts the A7 into a low power mode and only uses the M4 to do some basic processing. I'm starting with the OpenAMP_TTY_echo_wakeup example. In the example it says to issue the following commands:echo "*delay" ...
Hi,I've been trying to setup a cross compile environment using Docker for Windows, and I've run into a bit of trouble. I've setup the dockerfile so that during the build process of the image, I copy the SDK into the image and execute the .sh script.T...
Hello,I am reading a sensor on m4 side. And debugging in production mode for the target.I have called printf function in main.c but I cant see anything when I run the program.Is it normal that I cant see any console while the program running ?
Just wondering if I can edit the pinctrl.dsi file to change the pins to the Raspberry Pi header, rather than the HDMI encoder, so I can try DPI Raspberry Pi displays. In CubeMX the LTDC and most of the peripherals are locked, just wondering if it is ...
Hello,I am reimplementing the example application OpenAMP_TTY_echo in STM32MP157C-DK2.I want to exchange numerical data between M4 and dual A7. How can I do it ? which structure, channel or interface ?thanks in advance
Hi I use GT9147 touch IC on my stm32mp157 board. I found the stm32mp157c-ev1.dts use same chip. But the ev1 use GPIO14 of stmfx GPIO expander chip as TP_INT signal. The GPIO14 of stmfx configure as below code.486 hog_pins: hog...
Hi, I use system workbench to debug example project. The serial port and ethernet over usb are recognized by system workbench. Now, the debuger step is using openocd to connect target board. I follow the below link to setting the debug configuratio...
