Hi Nicolas L (ST Employee),I have read the past article that you provide sources and directives to allow building the Android 10 delivery for the STM32MP157C-DK2.Could you please send me the solution?I hope you will be able to reply to me.By the way,...
I am trying to create a custom board that boots from SDcard if an SDcard is plugged in, however, if the SDcard is not plugged in I would like the board to boot from the NAND. I want to do this programmable without the boot switch.Is this possible? Is...
I'm working with the DevBoard from Myir MYD-YA-157C which has the stm32mp157 MPU. I'm trying to chech the i2c from the M4 in the Engineering mode and have a problem.When I tied the I2C_TwoBoards_ComIT, it works. At least it generates the I2C5_ER_IRQ....
I've added OPENAMP through the middleware after enableing the IPCC interrupts, but now I'm getting the following error and an error in the actual OPENAMP source that's included!/opt/st/stm32cubeide_1.8.0/plugins/com.st.stm32cube.ide.mcu.externaltools...
Install the SDKSimple Hello World ApplicationI have followed all the steps for installing the SDK and verified the environment variables for the cross compiler. I use a make file and it generates a binary. The problem is it generates a binary for x86...
Hi all,I am using MPU ref. STM32MP153F, do you say me what is the time that elapsed between a tamper is detected and the backup resister are finishing erased?And the backup SRAM?Thank you in advance
Hi everyone!I want to use a hardware semaphore to access SRAM4 memory from both Linux and M4 firmware on STM32MP157A-DK1 board. There are no problems with the M4 firmware. But for Linux I have to create a driver. There is an example in this article: ...
HiWe are using stm32mp157a-dk1 board.We are writing code in bare metal.Its working fine when we run in SRAM.But when we jump to DRM its hanging.
The STM32MP157 demands a maximum time of 10 ms from reset command to boot partition data. According to JEDEC No 84-B51 the maximum time from reset command to the first data is up to 1 second (tBD):All data sheets of eMMCs that I found specify their b...
Hi,I want to make a bare-metal application (without Linux OS) on a STM32MP157C-DK2 Board.I need to use the usb host controller from this board (that why I choose it: multiples USB socket) but in the projects created with CubeIde, I can only assign US...
