Hello,The QC for STLINK-V3PWR assembled in France seems to be very bad. I received a unit that doesn't work out of the box (when USB is connected the status leds stay off, AUX power outputs 3.3V, host computer doesn't detect V3PWR).The same host comp...
Hi, I have an STM32MP135F-DK board, and I want to set LDO2 and get an output voltage of 3.3V. I have read a document ( Integration of STM32MP13x MPU product lines and STPMIC1D / STPMIC1A on a wall adapter supply) which states that LDO2 must be set af...
i have download the embedded wizard example from https://www.embedded-wizard.de/platforms/stmicroelectronics/stm32mp1 this website.now i am confusing that how i can run this builed example in stm32MP135 ?
My question is what the recommended values are for STM32MP151CAA3T (see image for Altium xsignals creation for the routing).I am currently doing routing and I could not find all this information in the datasheet.
Hello. I need to integrate a TI SN65DSI83 bridge with a DK2 board and one of the requirements of that bridge is to drive the data lanes to LP-11 state. What is the procedure to make that happen? I am assuming I need to make changes to dw-mipi-dsi / d...
Hello ST community,I am designing a board with STM32MP135 CPU and DDR3L based from STM32MP135F-DK.DDR stress test passed successfully and tf-a files are adjusted to have I2C4 on pins used in my design (SCL on PB13 and SDA on PB7).When I flash board t...
Hi all, I work on a STM32MP153 device and I used the command echo mem > /sys/power/state to put CPU A7 in Cstop mode, but I still have MCU running.I am wondering if a message via IPCC from MCU to MPU (that is stopped at WFI) can wakeup the A7 CPU.I...
Many thanks for your help!I have a custom STM32MP157c boards that works OK when the galcore.ko module is not deployed.When the galcore,ko module is deployed, the screen doesn't show up the usual image and after the boot image has been displayed, it s...
Hi all,I am designing a custom board using the STM32MP157CAD. But I haven't been able to get a lock on HSE crystal.Still on tf-a, I removed st,bypass to use the internal oscillator, also used the DTS generated by STM32CubeMX, following my PCB design....
Hello,according to drivers/gpu/drm/stm/ltdc.c stm hardware supports these pixel formats:enum ltdc_pix_fmt {PF_NONE,/* RGB formats */PF_ARGB8888, /* ARGB [32 bits] */PF_RGBA8888, /* RGBA [32 bits] */PF_RGB888, /* RGB [24 bits] */PF_RGB565, /* RGB [16 ...
