We're are trying to use BKPSRAM in application code insecurely. According to the stm32mpu BKPSRAM_internal_memory page, we need to "set BKPSRAM as non-secure and degrade low power modes support, removing Standby mode"Apart from setting the etzpc peri...
Is it possible to run touchgfx on the STM32MP1? TouchGfx can be run on the STM32F4 with the M4 core. Is this also possible on the M4 core of the MP1? Is there any support from ST or has anyone already implemented this?
Hello,Upgrading Linux 5.4 causes SPI to fail to initiate (see boot log snippet below). Any ideas what would cause this (same DT)?Again thanks for your great support!Best RegardsChrister[ 2.782226] spi_stm32 4000c000.spi: failed to request tx dma ch...

I've tried to flash STM32MP157C-DK2 SDCard like described in ST wiki with command STM32_Programmer_CLI -c port=usb1 -w flashlayout_st-image-weston/FlashLayout_sdcard_stm32mp157c-dk2-trusted.tsv.and it didn't work! i got following error report. it see...
I have a STM32MP157C-EV1 board.Can i upgrade STM32MP157C-EV1 board to STM32MP157F-EV1 only removing TM32MP157C processor and reinstaling a new TM32MP157F processor?If not, how can i upgrade MB1263 MPU subsystem daughterboard to the last microprocesso...
Hi!We are using mdma (dma0chan20) to do "memory to memory" transfers from the FMC to (user) RAM. The FMC is used to access a FIFO buffer that is filled by an FPGA (128kB size).Between individual DMA transactions we measure a delay up to 5ms leading...
Hello, teachers.I'm sorry in advance because I think I'll be talking too long.The board I use is STM32MP157D-EV1 (evaluation board).From the previous question and answer, I found that Ubuntu 18.04 and SDK could not be installed on my board, which had...
Hello, teachers.First, The board I am using is the STM32MP157D evaluation board.I checked the article that the starter package can be installed in Windowsos, but the developer package and the distribution package are only available in the Linux env...
