Dear sir/Mam While analyzing the reset handler code within the bl2.elf binary from Arm Trusted Firmware, we observed that the label S3_15_C2_C1_1 is being referenced in the cortex_a35_reset_func. We would like to request your clarification on the fol...
Hi All, can any one tell me what is the Maximum Speed of toggling GPIO on userspace and the kernel space.I was trying with kernel module programming with IOREMAP API i got 35 Nano seconds. but my requirement is maximum 8 Nano second, can any one plea...
HI With some help from @Gregory PLANCHON and @Olivier GALLIEN I can now boot the processor in M33-TD flavour. Our application wants to also use the Cortex M0+ for a very low power mode. How to use the Cortex-M0+ - stm32mpu tells how to do this from A...
Hi I am using a STM32MP257F-EV1 board, and I am trying to build the demonstration exampleSTM32CubeMP2/Projects/STM32MP257F-EV1/Demonstrations/StarterApp_M33TDI am using command line (not IDE)I have cloned and built TF-M for SDCARD_SDCARD and EMMC_EMM...
Hello all,Sorry if I'm not doing everything perfect about this post but this is my very first :).So i'm currently working on the STM32MP13 DK - Starter package (on STM32MP135F-DK)And when executing the command : STM32_Programmer_CLI -c port=usb1 -w f...
On the M4 core of a stm32mp157 I am using FIFO based FDCan communication.Messages are sent and received just fine but I think when I send too many messages in a short time some messages are getting lost.So I added a call to HAL_FDCAN_GetTxFifoFreeLev...
Has anyone here tried to stream Youtube or old playing games on STM32MP257?144p, 240p, 360, 780p, 1080p etc. Quake, Doom, Half-Life, perhaps Half-Life 2 as well. What was your experience and limitations? Very curious to know.
Hello all,I would like to use industrial cameras (for example GigE cameras, by using ethernet port) by connecting to STM32MP135F-DK and grab images. Is it possible and is there any instruction to do this?Thank you.
Hi Team, I am able to test "can0" module, from OpenSTLinux running on STM32MP257F-EV1 board, using the attached code "STM32MP2_Can0Test.c" compiled to binary (using AARM64 cross compiler from OpenSTLinux SDK) and PEAK PCAN Usb connected to FDCAN1 DB9...
