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_...
we want to read value of 1ch's adc evary 1ms by IIO. it it possible? (STM32mp151c)if it can not , how to does it read adc every 1ms. **********************************$ cd /sys/bus/iio/devices/trigger0/$ cat nametim6_trgo$ echo 10 > sampling_frequenc...
I have xfce running very well in the V1.2 Yocto Distribution system on the stm32mp157c disco board. The xfce desktop is very responsive and uses about 100M of memory. The xfce desktop using the latest V2.0.0 Distribution image however is very sluggi...
Hello,PLEASE GIVE SOME HELP.We made some boards based on MP157AAA and it ran good at first.BUT it can not boot anymore after someone turn off and on the power.No information comes from UART4 after turn on power switch.I change the boot-switch to '00...
Hello,I am new to Linux and just got a new DK2 board. I am attempting to go through the sample on the wiki site.Question 1:I have followed all the steps, but when I go to make the example, I get this error and am not sure how to address it (image mak...
