I am working on the STM32MP157A. Setting PLL in the STM32CubeIDE does not work as expected. 24 MHz HSE DIVM4 = /5 DIVN4 = X84 DIVQ4 = /5 should = 80,460,000 . The MX program says 80,960,039. I do not understand. If the MX program is right, then what ...
Hi Team,Please help on DMA driver part of STM32MP157 DK eval board and also the base address for DMA .RegardsSS
Hi ST.I set the clock in the dts file as below.&rcc { st,hsi-cal; st,csi-cal; st,cal-sec = <60>; st,clksrc = < CLK_MPU_PLL1P CLK_AXI_PLL2P CLK_MCU_PLL3P CLK_PLL12_HSE CLK_PLL3_HSE CLK_PLL4_HSE CLK_RTC_LSE CLK_MCO1_DISABLED CLK_MCO2_DISABLED >; st,clk...

Hello, I am working on the stm32mp157-dk1. I would like to create a 32bits parallel bus on cortex A7, at a frequency greater than 20Mhz but when I do a test on a pin I get a max frequency of 120khz, which is too low. I think this is the wrong program...
Hi,iam a bit confused aboute the remoteproc framework and if my understanding of it is correct.In my view, the remoteproc framework can start the m3 firmware with having its elf-file in a dedicated place of the filesystem. The remoteproc also parses ...
Hy wanted to make a kernel Module and i wanted to know whats the best way to acces the uart from Kernel Space.So far i enabled the UART in the device try and now i am able to send data. But now i know since the uart us in userspace i cant access it f...
Hi everybody,I have generated an STM32 project via the STM32CubeIDE and modified the large example buffer (the firmware logic analyzer part), trying to substitute to the timer generated DMA transfer a second stream from SRAM to SRAM.In the next futu...
Hello ST Community,I am starting to work with the STM32MP157C-EV1 board and working through the example https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-EV1/Let%27s_start/Populate_the_target_and_boot_the_image.While flash...
I have a question about the Starter Package.When I start STM32MP157x-EV1 (+en.FLASH-stm32mp1-openstlinux-5-4-dunfell-mp1-20-11-12), I get the following logroot@stm32mp1:~# dmesg | grep ether[ 1.642061] stm32-dwmac 5800a000.ethernet: PTP uses main c...
