Hi ST Team,We are working on product built around STM32MP157C. We are trying to generate the trusted image with Yocto. However, somehow the Trusted Firmware Arm (TF-A) is not getting generated. We have added following options in machine.conf file:BOO...
Is this processor capable to drive by parallel interface an RGB666 LCD display?What could I set in the device tree?
Hi,I have tried to migrate from ST Ecosystem 3.1 to 4.0.2 but I am unable to flash the image into the eMMC memory. My issue is similar to this one but I am using the Octavos SiP OSD32MP157c. As suggested by the original poster, the issue is probably...
In our custom board which uses STM32MP153C, right when TF-A is about to launch u-boot it displays PSCI power domain map logs and MPU reboots with MPSYSRST reason. Any idea what is the root cause? We are using the device tree based on the dk2 sample d...
I am asking because I want to remove some of them, how can I find out what are the names and what they do? What is the best way to do this?
We are trying to verify the signature generated by the STM signing tool. From this link, in the table for "On STM32MP15x lines", we need to know what data type is used for each field when the signature hash (sha256) is created so we can replicate it.
Currently our custom board powers up in two cases, one when you press the power on button, and another when you plug in the USB cable. We would like to disable PMIC from powering on when USB cable is plugged in. We see that the STPMIC specification d...
I was analyzing stm32mp15 disco and eval board schematics for my project. I noticed that DDR pinning are not the same between them. Disco boards have 512MB and EVAL boards have 2x512MB. My project also going to have two variants. I wanted to know why...
Hello we are using STM32mp153 for multiple products, and I'm considering buiding a generic TF-A bootloader with one device tree with all the clocks enabled for all the peripherals. I would like to do this in order to make it more generic across our p...
