Hello,I am working stm32mp157c. I'm trying to change the clock rate of stmcubeide using pll4q for spi45 (StmCubeIde outputs are attached.). Also The bsp setting is attached .Pll settigs is;   st,pll@3 {      reg = <3>;      cfg = <1 32 5 66 5 PQR(0,1,0)>;      frac = <0x1000>;   };I see the clocks are set correctly except pll4q (in linux "cat /sys/kernel/debug/clk/clk_summary" command).It turns out 25.125Mhz when it should be 6MHz (linux outputs are attached).I measure the pll4q clock with oscilloscope. Same as the value i see in "cat /sys/kernel/debug/clk/clk_summary" (not 6MHz, it is 25.125Mhz).Where do you think the problem might be?

Hello!I'm using MYD-YA15XC-T board based on stm32mp151 kernel 5.4.And wanted to share files with it via FileZilla ftp/sftp file manager on the PC.But i could not connect to the board, there is always login incorrect error, whichever login or password I try to use: My board uses automatic login, so there is no password that i know, really.And i believe the openssh-sftp package is installed.Do i missing something for sftp/ftp connection to work?Regards, Vlad.

Hi,We configured 1 uart for debugging purpose in our custom board at u boot level. Now we want to configure anthour uart for communicating with other devices.how do we configure second uart? For debug uart we use serial_putc() for transmit and serial_getc() for receiving .what are drivers we should use for transmit and receive data for second uart?

I am using stm32MP157F-DK eval board (on windows) and I would like to try the DDR testing tool on cubeMX. But this is my first time trying to do so - I try to follow steps in "U-Boot SPL: DDR interactive mode" (url: https://wiki.st.com/stm32mpu/wiki/U-Boot_SPL:_DDR_int). It states i should define this mode under CONFIG_STM32MP1_DDR_INTERACTIVE - but I dont understand when or how should I do that? Should this be done on full flashlayout_st-image-*** or should i just have boot running?

Hi,I'm using a STM32MP157a with yocto dunfell with 5.4 kernel version, and I'm trying to enable the kernel splashscreen. On my board I'm using the RBG lcd interface, and when the system is UP my application in showing curretly. On kernel config I have enabled the flags:LOGOLOGO_LINUX_CLUT224FRAMEBUFFER_CONSOLEbut no tux are showing at startup...Where I'm wrong ?

I am struggling to achieve a USB gadget with Mass Storage + rndis.When i start each service alone everything works but when i am trying to start both of them i receive the following error:dwc2_hsotg_ep_enable: No suitable fifo foundAny suggestion how to modify the dtsi in order to achieve it .Speed is not a conserne i can reduce the speed to full-speed as well.Thanks,Thanasis

On the STM32MP157C-DK2, can I use/interface the available muRata 1Dx with core-M4 only (& not core-A7)? I am not quite sure if the wifi module 1dx (U8 on the kit) is controlled by A7 or M4?Anyways, I want to interface it with M4. So, can it be possible?

After the OTG repeatedly switches the host and slave states, the HOST is no longer recognized

Hi STM-Team,I am working with STM32MP1 evolution board. It has 512MB of RAM memory. I want to load some custom data (1024 byes) in the last some offset of RAM memory (~500MB offset address). So, I am trying to use below command from u-boot prompt. But, getting error like accessing reserved memory.RAM Base address is 0xC000 0000 + 0x1F40 0000 (500MB offset) = 0xDF40 0000Case-1: STM32MP1>ext4load mmc 0:5 0xDF400000 file.binEntering do_loadargc:5argv[0]:loadargv[1]:mmcargv[2]:0:5argv[3]:0xDF400000argv[4]:file.bin** Reading file would overwrite reserved memory **File read ret:-28But, I am able to access the address offset ~381MB (0xD7DEF0DC).Case-2: STM32MP1> ext4load mmc 0:5 0xD7DEF0DC file.binEntering do_loadargc:5argv[0]:loadargv[1]:mmcargv[2]:0:5argv[3]:0xD7DEF0DCargv[4]:mtd3File read ret:01024 bytes read in 339 ms (2.9 KiB/s)Can anyone help me out to understand what is going wrong while accessing the RAM memory addresses around 500MB offset?Attaching the full logs file for refer

Hi,I'm using stm32mp157a-dk1 and I would like to use rpmsg_sdb for exchanging data buffers with the coprocessor (https://wiki.st.com/stm32mpu/wiki/How_to_exchange_data_buffers_with_the_coprocessor).I built the image for the A7 following the "STM32MP1 Distribution Package" tutorial without problem (https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package#Flashing_the_built_image).But in the dev folder I can't find the rpmsg_sdb device.Is there a prebuild image for A7 with this driver?If not, how can I add the recipe rpsmg-sdb-mod Yocto recipe to the image of the distribution tutorial using bitbake?In case, is there other ways to get the device rpmsg_sdb?Thank you in advance.Best regards,Andrea Segalla

Hi,I am trying to integrate swupdate for OTA update integration for STM32MP1.In the due process I will be in need to modify the flash layout file a bit , since I am trying have an extra rootfs partition , named partition B on /dev/mmcblkp06.I referred to flash layout currently mentioned here.It looks to me that there is not any support for the extra rootfs which is provided.How can i do that? I am sure that I will be in need to change the flashlayout but since offsets are defined static in the mentioned link , I was wondering what should be offset calculation for achieving the same.I want to achieve following scheme:#Opt Id Name Type IP Offset Binary - 0x01 fsbl1-boot Binary none 0x0 arm-trusted-firmware/tf-a-stm32mp157c-ev1-usb.stm32 - 0x03 fip-boot Binary none 0x0 fip/fip-stm32mp157c-ev1-trusted.bin P 0x04 fsbl1 Binary mmc1 boot1 arm-trusted-firmware/tf-a-stm32mp157c-ev1-emmc.stm32 P 0x05 fsbl2 Binary mmc1 boot2 arm-trusted-firmware/tf-a-stm32mp157c-ev1-emmc.stm32 PD 0x06 fip Binary

IDE suggested that I upgrade STLink FW on my STM32MP1-DK2 discovery board. Now when I connect my Linux PC to USBC on DK2, device isn't recognized by STMProgrammer (also nothing shows up in dmesg).

Hello,I am working on IPC between M4 and A7 and it works properly using the "logic analyzer" example. I changed it according to my needs but not the buffers. 1 . I could read the data from 3 buffers, but often buffers are swapping. I would like to what causes this problem and how to solve it?2. When I start IPC, one of the CPU processes goes into 100%. Is it normal for the IPC? and is there anything that I could change to reduce the CPU processes? Thank you in advance
