Hello,I tried to enable spread spectrum for PLL1 by adding a csg line to the TF-A DeviceTree:pll1:st,pll@0 { compatible = "st,stm32mp1-pll"; reg = <0>; cfg = < 1 49 0 1 1 PQR(1,0,0) >; csg = < 60 600 SSCG_MODE_CENTER_SPREAD >; };I tried several d...
Hi,on a custom board with a STM32MP153AABxx and a W63AH6NBV 1Gbit LPDDR3 memory I am failing to initialise the DDR properly. I made the required changes to the upstream u-boot device tree files, added support for UART8 debug console and some minor th...
HiWe are using stm32mp157a processor in our custom board.we have an 3 port Ethernet switch(KSZ9893RNXIA) with spi interface to processor.We enable Ethernet switch using spi.Read and write to switch is working properly.But we when we connect Ethernet...
Hi,During the actual production of our stm32mp157c products we do intend to use the HSM flow.But for now I am simply trying to test the SSP flow with some debug (development) keys and without access to an HSM.I went over:https://www.st.com/resource/e...
Hi STM-Team,We have the custom board based on the STM32MP157C-Eval board.In that, we are not able to access the eMMC from u-boot command prompt. Currently, we are booting from SD card and able to access it from u-boot command prompt.We are able to se...
Hello I created own machine based of seeed module. at the strartup there is info NOTICE: CPU: STM32MP157CAC Rev.B NOTICE: Model: STMicroelectronics custom STM32CubeMX board - openstlinux-5.10-dunfell-mp1-21-03-31 WARNING: VDD unknown INFO: Res...
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...
