Hi All,Can somebody point me what is a reason for 2 sec delay at PHY driver for LAN8742?I mean code below at function LAN8742_Init() inside file lan8742.c.if(status == LAN8742_STATUS_OK) { tickstart = pObj->IO.GetTick(); /* Wait for 2s to perform initialization */ while((pObj->IO.GetTick() - tickstart) <= LAN8742_INIT_TO) { } pObj->Is_Initialized = 1; }I am working at project with STM32H735 and ThreadX+NetX Duo. As PHY I use KSZ8081RNA, but I found that same delay need be there as at LAN8742 driver. Without this delay Ethernet does not work. With 2 sec delay works auto-negotiation with 100MB switch, but not with 1GB switch. For 1GB switch need be there ~3 sec delay.I am not sure what is going on here. I didn't found anything related to this delay at KSZ8081 datasheet, IEEE spec for auto-negotiation or at STM32H735 errata. I will be gland for any comment.Thanks.Regards,Jan

Hi,I have acquired a new STM32G031 microcontroller that has not been previously flashed and have observed an unexpected behavior when powering up my circuit prior to the initial software upload.Upon further investigation, I discovered that multiple registers were not at their reset values, but instead at different values that were not anticipated. Specifically, the registers of GPIOA (such as MODER) had critical (in my application) pins set to pull-up (e.g., MODER set to 0xEBEB FFAF).As such, I would like to know:Is the initial state of the registers documented anywhere? I was unable to find such information in the reference manual (RM0444.pdf).When in production with the final PCB already assembled, what is the safest approach to ensure the registers are at their reset values even when flashing fails (e.g erasing the device prior to flashing)?I appreciate your assistance with this matter.Note: While I understand that the safest solution would be to ensure that the external circuit can

I´m using the l9616-tr CAN transceiver, but i have no signal of CAN comuniccation, i think maybe tx and rx configurations pins are inverted.

Hi,​After I configure hospi1->Init.MemoryType = HAL_OSPI_MEMTYPE_HYPERBUS;​If I still want to send a command using CA[47:0] (or DQ[7:0]) and read back data such as device ID, how should I approach this? Is there an example code I can refer to?I am wondering if the command type (sCommand) needs to be OSPI_HyperbusCmdTypeDef? the max address is 32 bit but I need to send 48 bit.​or should I use OSPI_RegularCmdTypeDef? Then set MemoryType to HAL_OSPI_MEMTYPE_HYPERBUS later after I read all the data I want?Thanks in advance.

Hi, Is there any example of how to interface a NOR FLASH QUADSPI memory using the OCTOSPI interface used in the H72x, U5 or H5?

I am currently developing using STM32mp157fad and have a question. Here are the steps I have taken:Used STM32CubeProgrammer to upload the stm32mp157f-ev1 image to an SD card.Used STM32CubeMX to configure the GPIOs to be used with stm32mp157fad, generated code, and copied the device tree generated by the code generator to the SD card with OpenSTLinux installed.I'm wondering if this method is valid for use. If this is not the correct approach, I would like to know more information.

I am currently reviewing examples of the phrase 'WKPU'.Example is "SPC58xHxx_cut2_RLA WKPU Interrupt Test Application for Discovery".​If you press button sw0, LED3 turns on. If you press button sw1, LED1 turns on. And if you press button sw2, LED2 turns on.​What I'm curious about.​void wkpu0_int12_cb(WKPUDriver *wkpup);I'm curious about how the function is linked to the sw1 button. Can you explain that?​Likewise....void wkpu0_int18_cb(WKPUDriver *wkpup);I'm curious about how the function is linked to the sw2 button. Can you explain that?​And..​void wkpu0_int18_cb(WKPUDriver *wkpup);I'm curious about how the function is linked to the sw3 button. Can you explain that?​​​In conclusion, it's all the same question....​​help me ㅠㅠ​​

Dear all,ST brought a new feature to the STM32H7A/B and some L4+ MCUs, the "parallel synchronous slave interface (PSSI)". We would like to use this for a fast host-to-host communication. But this interface seem so new, we could only find register description in the RM0432 Reference manual. Are there any code example or app-notes for PSSI host-to-host communication?Thanks.

I am new to stellar MCUs. Please share information on how to get the SDK for stellar P series or G series MCU. Which IDE is used? Is there any RTOS support especially FreeRTOS support?

Hi expert,I am using Stellar SR6 P7 line, e.g. SR6P7C8. According to the SDK there is RAM and System RAM reset operation when system boot,/* Initialize memories protected by ECC */ bl _raminit bl _sysraminitI want to get more information about clearing memories for ECC. Why these step are needed? Is this for DAN-0055942? Thanks.

STM32 only connect VCC and UART2. Can it download programs with ISP(UART2 PA2-3)?​

I am using UART over RS-485 on an STM32MP153AAB3.The communication fails because the actual baudrate is off from the specified baudrate. With a specified baudrate of 9600 Bits/s, I am getting an actual baudrate of 9970 Bits/s, as you can see here (time per Bit is 100.3µs instead of 104µs): Changing the baudrate to 115200 Bits/s results in a time per Bit of 8.33µs, i. e. 120000 Bits/s: I set the USART2,4 Clock in the .ioc file to 64 MHz and chose PCLK1 as the source.The value in the BRR register is 0x1A0B which, if I understand it correctly, should correspond to a value for USARTDIV of 416, giving a baudrate of 9615 Bits/s (64,000,000/(16*416) = 9615). My settings are as follows:static void MX_UART4_Init(void) { huart4.Instance = UART4; huart4.Init.BaudRate = 9600; huart4.Init.WordLength = UART_WORDLENGTH_8B; huart4.Init.StopBits = UART_STOPBITS_1; huart4.Init.Parity = UART_PARITY_NONE; huart4.Init.Mode = UART_MODE_TX_RX; huart4.Init.HwFlowCtl = UART_HWCONTROL_RTS; hua

Hi community.. I am doing an application to display some text in a display 5 inches.. I am using stm32cubeide and touch gfx.. They are asking me to support the cyrillic and hebrew language.When i Set the text on the gui and i try to watch it statically it is working..  But when i try to do somethin shown below with the code i see ony question marks ?? in the display... textArea4.setColor(touchgfx::Color::getColorFrom24BitRGB(236, 209, 18));//extra time? Unicode::strncpy(textArea4Buffer, parArea4[tipolingua][5], Unicode::strlen(parArea4[tipolingua][5])+1); textArea4.invalidate();where parArea4 it is the following and it is giving problems when the language is cyrillic or hebrew.. const char* parArea4[5][6] = { { "Preheating", "Ready", " ", "Baking", "Extra time", "Extra time?" }, { "Preriscaldo", "Pronto", " ", "Cottura", "Extra time", "Extra time?" },

Im using a STM32F030C8T6 with PWM output to generate a sound output. I would like to use the repetition mode of the TIM1 so it will output the same PWM period 6 times.If I configure the timer and use both HAL_TIM_Base_Start_IT() and HAL_TIM_PeriodElapsedCallback(), I do get a interrupt after 6 repeats. ...... But the PWM output is not switching.Alternatively I can configure the system for HAL_TIM_PWM_Start() and HAL_TIM_PWM_PulseFinishedCallback() and the PWM output generates a waveform BUT I get an interrupt every cycle (not every 6th). Everything I have seen online seems to suggest that it should easily be able to generate several pulses and then interrupt once done.My thoughts are that this might be related to the output pin of the PWM not being initialized properly, but I'm open to any thoughts.

 last time also this problem was occured so I installed it again after that it run for some days now again the problem has occured. When I open Touchgfx one msg comeSorry - something unexpected has happened which caused an error to occur in the Designer.For more information, see the log file located at: C:\Users\Kaushal\AppData\Roaming\TouchGFX-4.21.3\TouchGFXDesigner.logPlease someone help to give the solution of it.

Hello,I am currently trying to set up a minimal example of using DMA for ADC conversions on a NUCLEO-F303K8 development board. I'm using the CMSIS device headers rather than the HAL, so I apologize if my issue is due to misunderstanding something in the reference manual.I have been able to set up the timer and ADC to regularly trigger the ADC interrupt on end of conversion and read the data, but I have been unsuccessful in implementing the DMA equivalent -- triggering a DMA transfer on end of conversion directly to RAM. I have been receiving DMA full transfer interrupts as expected (on the timing interval + conversion time), but the ADC reading transferred by DMA is garbage.Here's my full program:#include <stdbool.h> #include <stdint.h>   #include "stm32f3xx.h" #include "core_cm4.h"   #define ADC ADC1   #define ADC_DMA_CH DMA1_Channel1 #define ADC_DMA_IRQ DMA1_Channel1_IRQn   #define ADC_GPIO_PORT GPIOA #define ADC_GPIO_PIN 0 #define GPIO_MODE_ANALOG 0b1

AN2606 in description of Pattern 11 entry combination appears to indicate, that there's one combination when BOOT_LOCK option bit is ignored:However, this contradicts the RM:Can ST please clarify.Thanks,JW
