Hello everyone!I had an application that was originally designed to run on a STM32WB55 but found it didn't have the resources we needed for it. The STM32MP1 seems like it has the potential to be a good fit for us as we could do the sensor processing ...
I tried to probe g_multi to make sure that USB Composite was available.modprobe g_multi file=/dev/mmcblk0The log of the probe is as follows[ 501.458553] using random self ethernet address [ 501.461560] using random host ethernet address [ 501.4806...
Hello everyone,I am currently working with phyCORE-STM32MP1 which has a STM32MP157C mounted.It runs with OpenSTLinux, but it is a modified distribution by Phytec.I have very little experience with handling Device Tree and drivers and my problem is th...
I have found many tutorials for how to import the example projects into stmcubeide but have not seen much information on how to set up a new M4 project? I have been able to import the OpenAMP_TTY_echo example into stm32cubeide and debug fine but I am...
I am teaching a course in real-time embedded systems and in the past have used the STM32F4 MCUs running FreeRTOS, but would like to move to a microprocessor, specifially an STM32 MPU starter kit for students. So, does the STM32 MPUs support for a Re...
I want to control defined GPIO in DT in Applicatoin code. But I can't control this, please let me know how to control gpio with DT in applicatoin. 1) I can control GPIO in Application without DT . (unused at gpioinfo)2) I can't control GPIO in ap...
Hi,we have a custom board based on the stm32mp151c. It has on sdmmc3 a Silicon Labs WF200 Wifi Card attached. We tested this setup with the stm32mp157c-dk2 and it worked fine. Now, we do not see the message during bootup:mmc0: new high speed MMC card...
Dear Community,we are bringing up our own HW platform based on the STM32MP151A MPU. The use-case currently is that we obtain data permanently over several hours and store it on a sd card at a speed of max. 15MByte/sec. After the data acquisition we ...
This is might save someone the few hours I spent tracking this down. I am wondering if this is a bug. It would seem like a reason that you have m4 sections in the device tree. So linux can be aware not to touch an M4 resource. Linux shuts off the vdd...
