forced_mode of boot_ctx is always set to 3
Hello ST team,I came across issue here.The force_mode of boot_ctx is always set to 3, which force the MPU to boot over USB, rather than MMC. I tried to set TAMP_BKP20R(BOOT MODE) to 0, but the behavior is the same after reset.Aslo, I have another boa...
Resolved! STM32MP157A-DK1 Enabling and reading STGEN.
Hi, I am working with STM32MP157A-DK1 board with Yocto build system.I am trying to build synchronised system, that means I want to synchronise both CortexA7 and CortexM4. Basically I want to have the same time at both of them. I want to use STGEN for...
STM32MP1 CM4 SRAM cleared after WWDG reset
Hi,i want to store some flags, bytes, at the end of my SRAM. This RAM section should preserve the information in case of a Reset e.g. WWDG1 Reset.Before WWDG1 Reset is executed some program states should be stored in RAM and after Reset could be read...
Resolved! PCIe Probe Failed on STM32MP25 Series at Address 0x48400000
Hi everyone,I'm currently working on the PCIe part of the STM32MP25 and would like to ask if there's anything wrong with my configuration. I’ve followed the official documentation provided by ST.Here are the documents I’ve referenced:PCIe device tree...
STM32MP157DAC EVB: DDR3L Length Matching
Hi,I am referring to the STM32MP157D-DK1 EVB (STM32MP157DAC1), specifically the "mb1272-bdp" design file, and would like to clarify the correct method for measuring DDR3L to Microprocessor (MP) trace lengths on the PCB.My question is regarding the Cl...
Debug a crash handled in CDAbtHandler after a call to FileX function
Hi all,I'm working on a custom STM32MP135 SOC hosting a MMC memory. The original firmware creates some tasks by the osThreadNew() function and works correctly.Now I'm inserting FileX module on the firmware to support a FAT fs on the MMC memory.The fi...
STM32MP257FAL3 Can't access gpio 116
I am trying to control the LTDC on the STM32MP257FAL based on the STM32MP257F-DK board, but I am unable to configure pin PH4. This pin is used as LED1 on the STM32MP257F-DK board, which is the LED near the button. However, I cannot find where this pi...
SDIO support from expansion header on STM32MP157F-DK
I am using the STM32MP157F-DK board and attempting to connect an NXP Wi-Fi + Bluetooth module via SDIO through the 40-pin expansion header. For this, I designed a custom PCB with an SD card holder and connected the SDIO lines from the expansion heade...
Resolved! TEE IAC exception after Kernel prints "Started Calibrates HSI/CSI clocks" and crashes.
I have created a CubeMX project for STM32MP235.I have successfully built, Flashed and able to boot it on STM32MP257-EV1 board. (I don't have my 235 custom board ready yet.)Once I switch to normal boot after flashing, it runs until kernel tries to run...
