Hi: I plan to allocate can peripherals to m4, but I have a problem in calculating baud rate. How can I determine the baud rate after allocating to m4.

Hi, I have STM32MP157C-DK2 demo board and I have ported STM Linux Yocto into board. I have enable NTP in the bb layer and I am able to see the NTP is up. When I want to get the status using timedatectl status I am getting the following output Local time: Wed 2019-10-30 15:16:43 UTC           Universal time: Wed 2019-10-30 15:16:43 UTC                RTC time: Wed 2019-10-30 15:16:44               Time zone: n/a (UTC, +0000) System clock synchronized: yes              NTP service: active          RTC in local TZ: no Where we can find that NTP service is active but the time zone was not able to find. Defaultly it was taking UTC time zone.But I want to change the time zone to As

I can access it with the given tools, like bluetoothctl, but I cannot build that same tool, so that I can write my own code. It seems some header files or libraries are missed. Am I missing something?

Hi,I have created a layer with my custom distro config and altered the conf/local.conf to point to this new distro. So far so good, everything worked as expected.

Hi,Our board is base on STM32MP157C-DK2 and the HW difference are...1. DK2 CN7 USB Type-C is replaced by micro USB and removed STUSB1600.2. DK2 CN6 PWR-IN is replaced by DC jack and CC1 is 0.4v to PA4 and CC2 keep 0v to PA5.And we would like to program SD card (16GB, 8GB) by STM32CubeProgrammer with FlashLayout_sdcard_stm32mp157c-dk2-trusted.tsvThe programmer can connect to our board via USB and this tsv is work to program DK2.Meanwhile the BOOT pin configures as USB mode (000b).Show the entire log as below:17:58:45 : STM32CubeProgrammer API v2.2.018:01:10 : Read TSV File: D:\AIRD\LiDAR\firmware\release_image\DK2\DK2-Trusted\FlashLayout_sdcard_stm32mp157c-dk2-trusted.tsv18:01:10 : Number of partitions: 918:01:50 : USB speed : High Speed (480MBit/s)18:01:50 : Manuf.

I ask how can I program both the cortex m4 and the cortex a8 at the same time in mp1, can I pre-program both of them with cubemx or do I have to manually access the 8 cortex with openstlinux? are there any tutorials that teach you to do this?

  Hi all I have St-link v2 and I am facing a problem for debugging Cortex M in stm32mp157-ev1. I think it is because of the differences between HW Vesion and FW in keil document and my results.     In attachment image is mentioned stlink v2-1. Shall i use Stlink V2 instead of V2-1? How do I change my version of the Stlink from V2 to V2-1? Best regards    

Hi. I have generated a full device tree for the EV1 to add I2C5 pins PA11/PA12 for external connector hookup to some of my I2C widgets using STM32CubeMX.

Hi,Has anyone tried to build latest stm32mp linux release (v4.19-stm32mp-r3) for stm32mp157c-dk2 board? In STM32MP15 ecosystem release v1.2.0 st provides linux v4.19-stm32mp-r0 with some r3 patches and external fragment configs. While I am trying to build latest linux release for dk2 board, usb related drivers fail to build. I have applied provided patches and fragment configs. Is there any way to build and use latest stm32mp linux release with yocto or buildroot?Build logs are attached.

Hi Folks,i created a custom dts and build it via the mx-addons howto. My goal is to activate USART3 on DK2. For USART3 is create the following source in the DT:&usart3{ pinctrl-names = "default", "sleep", "idle"; pinctrl-0 = <&usart3_pins_a>; pinctrl-1 = <&usart3_sleep_pins_a>; pinctrl-2 = <&usart3_idle_pins_a> status = "okay";   /* USER CODE BEGIN usart3 */ /* USER CODE END usart3 */ };   usart3_pins_mx: usart3_mx-0 { u-boot,dm-pre-reloc; pins1 { u-boot,dm-pre-reloc; pinmux = <STM32_PINMUX('B', 10, AF7)>, /* USART3_TX */ <STM32_PINMUX('G', 8, AF8)>; /* USART3_RTS */ bias-disable; drive-push-pull; slew-rate = <0>; }; pins2 { u-boot,dm-pre-reloc; pinmux = <STM32_PINMUX('B', 12, AF8)>, /* USART3_RX */ <STM32_PINMUX('B', 13, AF7)>; /* USART3_CTS */ bias-disable; }; };   usart3_sleep_pins_mx: usart3_sleep_mx-0 { u-boot,dm-pre-reloc; pins { u-boot,dm-

I am using rpmsg and OpenAMP framework for ipcc implementaion.I am trying to send some data from Cortex M4 to Cortex A7. Data array consists of integers of type uint16. But this transaction is happening properly. But when i use uint8, data is transferred properly. My question is, Is there any limitation on the data type in buffers? How can i send data of bigger data type to A7? Please help.

Hi, What mean kmsdrm no support dynamic loading ? But for example X11 can be dynamic loaded.I check this when try build SDL, but are there some another options to check dynamic loading in system ?Adrian

I can't connect to my STM32MP157 evalaution board.
