about Memory
hi there I have a question about Memory 。Are the memory regions starting at 0x10000000 and 0x30000000 part of the same mapped area?Are these addresses written the same way in the device tree, or is there a difference between them?thanks，csm
Resolved! HSP051-4M10 on STM32MP257-DK board?
Hi,just a quick question to understand the hardware of the STM32MP257 development kit board: there are several ESD-protection components of type HSP051-4M10 used.What is the exact purpose of them, are they therea) because the DK-board is intended to ...
Boot Failure on STM32MP157C: Secure Mode Issues (smc execution failure)
Hi, I am working with an STM32MP157CAA Rev.Z on a custom STM32CubeMX board running OpenSTLinux 6.6 (Yocto Scarthgap MPU v24.11.06). I have successfully integrated and bootstrapped various boot components.I first got the TF-A and OPTEE to boot the sys...

Resolved! Using Only the M33 on the STM32MP2: Feasibility and Peripheral Support
Hello everybody.On STM32MP2, is it possible to operate only the M33 like a microcontroller, without booting the A35? Also, if only the M33 is operated, can major peripherals such as I2C and Ethernet be controlled from the M33? (I assume that PCIe wou...
Resolved! Wiring between STM32MP257 and RAM?
Hi,on the STM32MP257-DK board, the wires between the MPU and the RAM have an interesting shape:What is the reason for these non-direct wires? Have the same length for all the wires? Shielding? Some noise-thingy?Thanks!
