Hi STM-Team,I am working with STM32MP157F-Eval board. I have enabled and tested secure-boot flow as per https://wiki.st.com/stm32mpu/wiki/STM32MP15_ROM_code_secure_boot.Now, I am looking for next security part for singing-verification of kernel & DTB...
Looking at the code, i see file sf_probe.c with .id = UCLASS_SPI_FLASH, that performs the id reading. How can i use stm32_spi.c with .id = UCLASS_SPI, driver instead? and send "raw" spi data?
I noticed that after I flash the ST starter package root filesystem, at first boot there is a check on bad blocks and a resize of the partitions, while when I flash the exported root filesystem, there is no checks and some partitions are not resized ...
Hi,I am designing a product which requires RGB interface length matching. For that I want Pin Delay/ Pin Length from die to ball for STM32MP157CAC3 MPU.If possible please provide Pin Delay/ Pin Length from die to ball for all available pins in STM32M...
If I'm interpreting Table 13 correctly (datasheet p 128), VDDA can be set to 0 volts provided VREF is not used. Similarly power pins related to USB can also be set to 0 volts. Looking in the datasheet p29,I just need to star-connect VDD_ANA, VDD_PLL...
HelloI am using Distribution Package and st-image-core.I had to use sftp while testing my board, so I tried it, but it doesn't seem to be installed in the default package.So, after adding the following to st-image-core.bb, I tried bitbake, but an er...
Hello.I developed my own board based on A-DK1 board using STM32MP157CAC and MicroSD, PMIC, Ethernet and DDR periphery. When I connect my plate to the usb with sd-card (st-link 2.1) I always receive the message:PANIC at PC : 0x2fff2d17Exception mode=0...
I've been trying to build-time reserve a 64KiB memory region anywhere between 0xC0000000 & 0xDFFFFFFF for the Cortex-M4 core using a device tree reserved-memory node. I've tried 0xC0000000, 0xD0000000 & 0xDFFF0000 but each time U-Boot fails either du...
Hello. I have used the STM32MP157A-DK1 this year and I have learned to work with it. Now I develop my own PCB with STM32MP157CAC3. There is a 12-V external power supplier in it. I do't use USB Type-C. Can I do like this? I care about pins USB_PWR_CC1...
