Hi all,I have small query around u-boot.How can i update my custom boot screen for the u-boot?How can add my custom application to start post boot?Thanks.

Hello,I am trying to get familiar with vitualUart between A7 et M4 side.The example OpenAMP_tty_Echo given in the wiki works well with my setup.Next step i would like to replace the "echo "msg" > /dev/ttyRPMG0" terminal commands" by a C linux user space application by using Read/Write file operations.Writing operations work OK but i am struggling to get the Echo with read operation.No change made on the M4 echo example.Below an extract of my GTK c programWhen read operation is reached the program blocks despite the timeout settings.But when I echo the M4 with a terminal M4 is still alive. And a very interresting thing is that this echo gives also the caracteres sent with my GTK c app.I did not find any example on the web for this task.Thank you by advance for any help.Regard serial_port = open("/dev/ttyRPMSG0", O_RDWR); struct termios SerialPortSettings;    tcgetattr(serial_port, &SerialPortSettings); SerialPortSettings.c_cc[VTIME] = 10; w

Hi, We have acquired this board called Audio Injector (in the image) that has a WM8731, it is a raspberry pi hat, but we want to use it with the STM32MP157D-DK1 but the drivers we have found on the internet seems to be not compatible with this board (we are using the base OpenSTLinux), despite the board has the pinout of raspberry. Someone has used it before? Another question, how can we manipulate the Cortex M4 from the Operating system? there is a way we can use it capabilities from the OS? because we noticed that for the Cortex A7 we cannot use the SAI ports as I2S but from the Cortex M4 is possible to use them as I2S. (we saw that on the STM32Cube IDE and CubeMX).Thanks for your answer.

1. Using a virtual machine in Windows, DOWNLOAD hangs when the virtual machine is turned off while downloading LINUX OS and BOOTLOAD to USB.2. Subsequent USB not recognized by Windows and LINUX.3. Hardware check confirms over current in PCB, overheating in USB recognition IC (USB2514B) - this circuit has no external connection other than MPU and power.4. Estimate, is it right to estimate that the internal program is incompletely downloaded and the MPU is abnormal operation as the OS downloading occurs?5. I want to reset the software to recognize USB again and download it again, what should I do?

Hi everyone,I'm working with OpenAMP on CM4 and I would like to increase the buffer size of RPMsg messages. When sending with VIRT_UART_Transmit() from CM4 to CA7, gives me an error when the message exceeds 496 bytes due to the RPMSG_BUFFER_SIZE value in rpmsg_virtio.h, which is set to 512 bytes.Aiming to reach 1024 bytes in size, when I set that value, RPMsg keeps giving the same error. Why?This is my simple code:void t0Task(void *argument) {   int i;   int count = 0x0, simulated_channels = 64;   const int SIZE_DATA = 7;   unsigned char msg[SIZE_DATA * simulated_channels], msg2[SIZE_DATA];   while (1) { strcpy(msg,""); for (i = 0; i < simulated_channels; i++) { sprintf(msg2, "%06X ", count); strcat(msg, msg2); count = (count + 1) % 0xFFFFFF; }   if(VIRT_UART_Transmit(&virtUART0, (uint8_t*)msg, strlen(msg)) == VIRT_UART_ERROR) { VIRT_UART_Transmit(&virtUART0, "Error size\n", 20); } osDelay(1); } }Note that messages

Hi,I want to communicate data between two cores i.e,cortex A7and cortex M4.Can anyone share IPCC example code for Both M4 and A7 in stm32mp157A

Is there no driver support for VBAT and VSENSE monitoring via ADC on Linux for STM32MP157C?

Hi,I am working with the STM32MP157c-DK2. All examples are working fine, but now I would like to use custom code. I generated some code using CubeMX for the development board. I used the default settings and enabled FreeRTOS additionally. I compiled the generated device tree file and pushed it to the board. Afterwards, I booted Linux on the A7 processor and launched my compiled FreeRTOS code on the M4 processor using remoteproc. The application crashed. I used the eclipse debugger to locate the problem: The application crashes, while trying to start the first RTOS task, when calling the function prvPortStartFirstTask( void ) in port.c. As an error message the deugger gives meError: stm32mp15x.cpu2 -- clearing lockup after double fault Polling target stm32mp15x.cpu2 failed, trying to reexamineI didn´t change a single line in the code generated from CubeMX. Any suggestions why my application crashes? Thank you for your help.Robin

Hello everyone I want to use external power for my STM32MP157A-DK1. I connect 5 volts directly to the Raspberry Connector. But the U-boot in the console tells me that I should use USB Type C. How do I change the U-boot so that I can use more than just USB Type-C

Hi All -I was attempting to build the Qt example images for the DK2, following the wiki directions here:https://wiki.st.com/stm32mpu/wiki/How_to_build_and_use_an_SDK_for_QTI got to the step where it's building the SDK, after compiling the image successfully.PC $> bitbake st-example-image-qt -c populate_sdkAnd got a compile error:arm-ostl-linux-gnueabi/9.3.0/ld: .obj/moc_qgeotiledmaplabs_p.o:(.data.rel.ro+0x70): undefined reference to `QGeoTiledMap::setCopyrightVisible(bool)'| /home/mtd/STM32MPU_workspace/STM32MP15-Ecosystem-v3.0.0/Distribution-Package/openstlinux-5.10-dunfell-mp1-21-03-31/build-openstlinuxweston-stm32mp1/tmp-glibc/work/cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi/qtlocation/5.14.2+gitAUTOINC+feb604c326_d9577fdebe-r0/recipe-sysroot-native/usr/bin/arm-ostl-linux-gnueabi/../../libexec/arm-ostl-linux-gnueabi/gcc/arm-ostl-linux-gnueabi/9.3.0/ld: .obj/moc_qgeotiledmaplabs_p.o:(.data.rel.ro+0x80): undefined reference to `QGeoTiledMap::clearScene(int)'| /home/mtd/STM32MPU_wor

hi, I have been working on compiling an openstlinux image with yocto, when compiling the image with bitbake it does not show me any error, but when mounting the image on the SD card it shows me the error that it cannot find "uInitrd", check in the bootfs partition and indeed the file cannot be found, however, if I first mount the partitions using the started package and then mount the generated image ignoring the bootfs partition, the operating system boots.I have not found a reason why the uInitrd file is not generated, I would greatly appreciate the help.

Hi there!   I just purchased an STM32MP157D-DK1 discovery board, and noticed that in STM32CubeIDE there are no definition files for this model, only a subset of the other MP1 discovery boards (but curiously not all of them).   Is this product unsupported by ST or can I obtain board definition files from elsewhere?   Thanks.

Hi all,What is the most correct and easiest way to generate dtb for the STM32MP1?I tried following this : https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_PackageLooks way complicated and I get below error :/opt/st/stm32mp1/3.1-openstlinux-5.10-dunfell-mp1-21-03-31/sysroots/x86_64-ostl_sdk-linux/lib/libc.so.6: version `GLIBC_2.33' not found (required by /usr/lib/gcc/x86_64-linux-gnu/10/liblto_plugin.so)post that came across workshop video which does it in few steps.https://www.youtube.com/watch?v=XhB0rGLjl_Q&list=PLnMKNibPkDnFeV4sBarnsAtFTg7h6V-9_&index=9I couldn't seem to get it up and compile file in any case? I mean it exists cleanly but not dtb gets generated?What i might be missing here?

Hello,I try to make a simple PWM work on PD15 with TIM4_PWM4, wich normally output the PWM on D6, the 6th pin of CN14. I followed example of https://wiki.st.com/stm32mpu/wiki/PWM_overview as I only need two PWM controlled with sysfs (the first beeing PE9 like in the example).For a reason I don't understand doing the same with TIM4CH4 don't work. Do someone have any idea what is laking in my configuration of TIM4CH4 ?Here is my device tree : stm32mp157c-dk2.dts/* PWM DT provider on TIM1: "pwm1" */ &timers1 { status = "okay"; /* spare all DMA channels since they are not needed for PWM output */ /delete-property/dmas; /delete-property/dma-names; /* define pwm1 label */ pwm1: pwm { /* configure PWM pins on TIM1_CH1 */ pinctrl-0 = <&pwm1_pins_a>; pinctrl-1 = <&pwm1_sleep_pins_a>; pinctrl-names = "default", "sleep"; /* enable PWM on TIM1 */ status = "okay"; }; };   &timers4 { status = "okay"; pwm4: pwm { pinctrl-0 = <&pwm4_pins_a

I am using STM32MP157C and as part of the project i am trying to configure the hardware by enabling and disabling certain security features(tamper detection,trust zones,rd and wr protection etc)I would like to know if there is a way to access the system registers for these features and write to them using the A7 in the Stm32.

i followed the setup procedure described in the youtube video https://www.youtube.com/watch?v=qEzfqKt3exE.i checked the path that is displayed in the error message and it does exist. the file the debug session is trying to write to is the name of the executable and it does exist.any help in understanding what this error means would be appreciated.thanks,vince
