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...
Hi,i have done some Benchmarktest via Rpmsg and iam getting following results:Maximal datarate sending data from M4 to A7 4.359 MB/s.Maximal datarate sending data from A7 to M4 9.16 MB/s.Now iam not sure why reading from A7 side is so much slower tha...
Hello everybody,i have a problem booting the SD card. The problem occurred after I copied the device tree (.dtb) from my project from STM32CubeMx to the STM32MP157A under / boot. When booting, the U-Boot and the start kernel run endlessly. How can I ...
I see that the OpenAMP_TTY_echo example uses the stm32mp15xx_retram.icf file in the EWARM. But thereis also an stm32mp15xx_sram.icf file. Can someone please point out the differences between the two ic files and why the OpenAMP example used the retra...
