Hi,I'm using OpenST-linux version 4.9 on a STM32MP157c-ev1 and I wrote a simple script to run my firmware for Core M4. I would like to know how I can make the script run automatically after system boot.Here's my script if could of any help for answer...
SAI2 Block A configured as a MasterTX and works. Fs configured for 48KHz, bit clock configured as 64*Fs and MCLK as 256*MCLK. I've verified these signals are sent to the audio codec which is configured as a slave (receives MCLK, SCLK, LRCLK (Fs)). Th...
Hi dears I wish you a good day ,I am working on my bachelor graduation prohect which is ( an overcurrent protection relay design ) and I using an STM32MP1 to have all the functions and required controlling inside it. And I want to add a communicatio...
Hi, I know that the ecosystem is already at 3.1.0 or higher, but we started our project in 2019 and working with image based on that release (1.0.0) and don't plan to upgrade.I wanted to send a link to the SDK from your website to our customers, but ...
/* USER CODE BEGIN PD */ #define ADC_BUF_LEN 4096 /* USER CODE END PD */ ... /* USER CODE BEGIN PV */ uint16_t adc_buf[ADC_BUF_LEN]; ... /* USER CODE BEGIN 2 */ HAL_ADC_Start_DMA(&hadc2, (uint32_t*)adc_buf, ADC_BUF_LEN);I've got the above code ...
I'm building an elf file, SCPing it to the controller and using the fw_cortex_m4.sh to load it on the m4, but no matter what I set the APB2DIV scaler to the number of times per second TIM16 is called doesn't change. The only thing that does seem to ...
Hi dear all,I'm looking for dual ethernet examples to implement with my stm32mp157d MPU , but I couldn't find anything on the internet.I've seen that there is no STM32 with dual ethernet interface but i want to add dual ethernet and fiber ports to my...
Hi,I'm using a custom buildroot build (2021.11) with linux 5.15.13, on the stm32mp157f-ev1 board.I can load an .elf M4 firmware into the M4 core and start it, using /sys/class/remoteproc/remoteproc0However, I can't use the debugging feature of STM32C...
I am using MB1407C (stm32mp157x-DK2 extension board with touch-screen) connected to my custom board. When board is booting I am getting the "ST life.augmented" screen on the U-boot and black screen when kernels starts. Also I am getting the telnet co...
hi,I am working with a custom board based on the STM32MP157C. I use a lan9303 chip which is acting as a switch for ethernet. In the linux kernel, there are no problems with the ethernet but I can't get it to work in u-boot. Even when I use the same D...
