strex calls DAbt interrupt
Processor stm32mp157it runs Opencv in baremetal modesingle-tasking environment.when calling a methodvoid UMat::addref(){if( u )CV_XADD(&(u->urefcount), 1);}we get DAbt.The disassembler shows a set of instructions 388 CV_XADD(&(u->urefcount), 1);c013c...
Resolved! STM32MP157 GPIO access
Hi team,I have an STM32MP157 board with a Cortex-M4 processor. I have a simple task, which is to toggle the GPIO at maximum speed with accuracy, ensuring that the clock width does not vary.The maximum toggle speed we require is approximately 15ns bet...

I have an STMP157F-EV1 and I have followed the instructions here to download and program the starter package. Everything works as best I can tell except the remote console hangs just after the initial login messagestm32mp1 login: root (automatic log...
Enabling PWM buzzer in STM32MP13X UBoot
Hi,We are working on developing a custom board that necessitates the immediate activation of a buzzer with a predefined frequency as soon as the board is powered up. We are exploring the feasibility of utilizing the PWM driver in U-Boot to achieve th...
Resolved! STM32MP135D u-boot _regulator_enable:169 regul usb33 set state failed with 0xffff0000
I am trying to create a new board based on STM32MP135D.An error occurs while running u-boot on optee layer.The log below is the log where error occurs. Full log is attached as file. Hit any key to stop autoboot: 0 Boot over usb0! D/TC:? 0 tee_ta_in...
Resolved! Automated unit testing for Yocto builds
Hi! Is there a way to run unit tests automatically on the STM32MP157-DK2 board? I've managed to flash the device using the STM32 Programmer CLI, but after flashing, I need to manually switch the bootmode to boot from the SD-card.It would be great if ...
Resolved! There is no audio data output from the 3.5mm headphone jack after the HDMI node is disabled
Sorry to bother you.I don't need the HDMI chip(sii9022) in my project. So, I first removed the HDMI chip on the STM32P157F-DK2. In fact, I manually removed it with a soldering iron. My SDK and development environment are based on "stm32mp1-openstlinu...
Gigabit Ethernet GMAC on stm32mp157a
hi,st engineer I am required to conduct Ethernet debugging on an stm32mp157a-st-discovery development board running the RT-THREAD operating system. Within the stm32mp157 Processor Reference Manual, I've encountered such option as follow:10/100M Gigab...
