Dear All,We are designing a custom board based on STM32MP1. In some ST documents we can read "if no external battery is used, it is mandatory to connect this pin [VBAT] to VDD." If I check the developpement board schematic VBAT is simply connected to...
The handshake sequence looked a bit odd too. [STMdemo1] (08:07:40): {"state": {"reported": {"Device_Type": "STEVAL-IPD005V1", "Features": [], "Firmware": ""}}}Update request with token "40d4c70c-ec71-4946-9f7b-b6ad2719d965" acceptedI have also tried ...
Hi guys,I'm designing a custom board with STM32MP157C using the MB1263 board as reference.The MB1263 reference design shows the VDD_OTP pin tied to VDD, which is 3V3 for that particular board. My custom board uses VDD = 1V8 instead of 3V3. Should I t...
Good afternoon. I tried to check your example OpanAMP_TTY_echo together with the ssh-t ttyRPMSG0 command after trying to execute the ssh-t ttyRPMSG0 command, the terminal responds Error resolving ttyRPMSG0 port 22 Temporary failure in name resolution...
We would like to build the TF-A image with a different muxer settingfor i2c4. The usual setting is:i2c4_pins_a: i2c4-0 { pins { pinmux = <STM32_PINMUX('Z', 4, AF6)>, /* I2C4_SCL */ <STM32_PINMUX('Z', 5, AF6)>; /* I2C4_SDA */ bias-dis...
Good day, I solved one problem how to connect to stm32mp157a-dk1 over tcp. In the console, you need to write ifconfig eth0 192.168.1.5 ; net data-P ttyRPMSG0 ; net data-p8888 but I do not see data in the buffer ttyRPMSG0. in my program OpenAMP_TTY_ec...
Hello Everyone I wanted to Install Buildroot on my STM32MP157-DK2 according to this website:https://bootlin.com/blog/building-a-linux-system-for-the-stm32mp1-basic-system/Unfortunately as a beginner with OpenST-Linux and Yocto I got stuck at that ste...
I am trying to get this board up and running again after being away from it for a while, but I've been running into problems trying to boot from the SD card. I followed the instructions from the wiki here: https://wiki.st.com/stm32mpu/wiki/STM32MP15_...
