I've been trying to reduce power consumption of the STM32MP157C-DK2 board and have a very low power linux platform. But the power consumption seems somewhat agnostic of power rails and clock rates. For example, I removed the LCD, I boot to u-boot, th...
I added nand flash to stm32mp157aac, but the nand startup mode is always DFU mode, may I ask what configuration is needed?Nand boot has been selected on the hardware
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
