Possible to use STM32MP1 for smart wearable device?
Hi everyone,I am thinking about using STM32MP1 for a smart wearable device, like a smart watch to run some machine learning algorithm. is it possible? is the battery able to support MPU?Does anyone know any product already used STM32MP1? it would be ...
Unable to get Spread Spectrum working on STM32MP157
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...
Cannot access LPDDR3 memory from a STM32MP153AABxx
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...
Resolved! Regarding Ethernet Ping Issue in stm32mp157a
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...
Resolved! secure secret provisioning (SSP) without HSM question
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...
Resolved! Not able to access eMMC from u-boot on STM32MP157C device
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...
