Hi,we want to use the STPMIC1A for supply of an STM32MP157 custom board and its LDO2 to supply a SD Card. At the moment, a flashing proccess during EOL is not planned and my customer wants to boot from SD Card.As this LDO2 is programmed as 1V8 by factory, the SD Card will not come up. We want to increase its voltage by an external power supply during first boot (from SD) and during that, the PMIC will be reprogrammed in a way that LDO2 will supply 3V3, so the external power supply is not needed anymore.As the LDO2 output voltage is lower than Vin of LDO2 and LDO2 is not monitored,I did not find any restrictions, which are against my idea. Can you confirm, that if Vin and LDO25IN is 5V, and LDO2OUT (programmed default as 1V8) is superimposed by 3V3, the PMIC will not be damaged and not shut down?Thank you,Florian

When downloading FW on the stm32L476ZGT EVAL by using CubeIDE1.10.1ver, I faced with Error: Failed to download Segment[0], Error: Failed to download the File...,How can I solve these problems? Even I didn't write any code in there. Following is my Console window...If you guys have any good ideas, please save me...I uninstalled CubeIDE 1.07ver and installed CubeIDE 1.10ver but it wasn't working.  STMicroelectronics ST-LINK GDB server.

We are using the CR95HF over SPI and communicating with a single NTAG213 tag.I can successfully configure the reader and read 4 pages of user memory reliably using the READ command: 00 04 03 30 04 28. // Reads 16 bytes from Addr 0x04We would like to read multiple blocks using the FAST_READ command but the following command structure gives an 0x87 error;00 04 04 3A 04 07 28Any idea why this doesn't work?

I have the following code where the variable string takes on the float value toPC correctly. I step into the HAL_UART_Transmit_IT and step over all the assignments and all looks fine yet I never see the TDR register update with the first value. Furthermore my while loop just hangs. Should I be doing something else for the uart to send data??I am connected to the STLINK port on the board and have the UART configured for 19200, 8 bit, No parity and I see nothing come over the port. The TE, RE, UE and TXEIE bits in CR register are all set.Thank you for (uint8_t k = 0; k < NO_ADC_CH; k++) { static char string[7]; ISR.usart_txToPC = F; /* * LMT87 linear equation * T = V - 2.6355 / -13.5mV * equation represents 0C - 50C */ float toPC =(((float)(stream[k]) / 4095 * 3.3) - 2.6355) / (-0.0135);   sprintf(string, "%2.2f\r\n", toPC); HAL_UART_Transmit_IT(&huart1, (uint8_t*)string, strlen(string)); while(!ISR.usart_txToPC); }  vo

I'm a beginner in working with Embedded Systems. I'm confused over OpenSTM32 System Workbench and Cube IDE. Could you please clarify me on this.Thanks

I'm trying to send CAN messages with the STM32F103C8T6 microcontroller (blue pill hardware with genuine ST chip) to a CAN analyzer without success.I'm using STM32CubeIDE v1.12.0. I double checked the hardware, I'm using PB8 and PB9 pins to connect to the CAN transceiver (SN65HVD230 ) RX and TX pin respectively, I have 120 ohm resistor on both CAN line termination, I settled CAN baudrate to different baud but the result is always the same, no pin level changing on TX pin PB9, it remains always at 3.3V (looked with a scope meter), it seems that the CAN cell is not connected to the external pins. I'm not using the USB that is disabled, external 8 MHz crystal with PLL to have 72MHz clock. The code works because I have a LED that correctly toggle its status every 1 second, after a while the CANtransmit function HAL_CAN_AddTxMessage(..) return an error because it doesn't find a free trasmit mailbox. Attached the main function, please help

Hey!!I have a BLE application which runs on custom server profile. There are few characteristics of a given service, where the client can modify them. I want to read these characteristics once they are updated by the client. I have tried to use "aci_gatt_read_handle_value" API but I'm not sure whether my implementation is correct or not.My implementation: ZoneConfigurationStatus_t zoneStatus; aci_gatt_read_handle_value(CustomContext.CustomZone_Configuration_StatusHdle, 0, SizeZone_Configuration_Status, &SizeZone_Configuration_Status, &SizeZone_Configuration_Status, &zoneStatus); LOG_DEBUG("zoneStatus :%d", zoneStatus);Can anyone help me out with this?Thanks,Akash

We are using LPDDR2 and have wired the data bits as per the ST provided example STM32MP15XXAD_LPDDR2x16-Example-A01_Schematic.PDF (attached)We have swapped the same bits in the DQ15:8 byte as per the PDF but I can't find anything to tell me how to perform this swapping in the devicetree or otherwise.Below is the screenshot from the Application Note detailing that bit swapping is possible.

Hello,We observe issues with a set of stm32F407ZETx.The application stalls / hangs somewhere while calling MX_USB_DEVICE_Init(). We are using the USB in CDC class. The board is powered via a USB cable, and the issue is not observed when using a good-quality USB power block, but it is observed if we e.g. put a dongle in between (https://us.transcend-info.com/product/card-reader-accessory/hub2). The production site (in a different country) is also observing these issues, I'll ask if they use a hub as well.The application seems to hang, but I could not pinpoint where exactly, since the program counter register suddenly becomes 0x0!!! That seems to happen on a random place during MX_USB_DEVICE_Init(). Sometimes, the application recovers automatically (on the production site, they say that the startup time usually takes 2 minutes instead of 3 seconds), but on our reproduction setup, the application never recovers automatically.Surprisingly, the application DOES recover if we touch the groun

I've recently updated our application from 4.18 to 4.20, and I've noticed a couple of rendering errors with TextArea. They occur when setWideTextAction() is set to WIDE_TEXT_WORDWRAP, and the text area wraps.The first problem is related to multi-line text areas. When calculating the bounding box for rendering, it only considers with width of the first line. If the second line is longer than the first, it is truncated. This has already been reported (search for "touchgfx truncated line when using word wrapping"), but there's no resolution there. Regenerating the project does not help me.I've done some investigation, and the issue appears to be in TextArea::calculateBoundingBox. It correctly calculates the height of the bounding box, but the width is set to the first line of text only. If the second line is longer, it gets truncated when rendering.I've looked at the code in TextArea.cpp; specifically, this section (lines 266-277):do { wtis.getStringLengthForLine(lineHeight * 2 > widg

Dear Sir,In datasheet, it says that Angular rate zero-rate level is +/- 1dps,does it means that when the chip soldered on PCB and in flat stationary state, the expected value is +/- 1dps or close to +/- 15 counts for +/-2000dps scale?What is the min and max G_TyOff? Not found in datasheet.Thanks.

Hello all,I am working on dual core stm32wl55.If the start address of CM4 is 0x08000000 and the start address of CM0 is 0x08020000, then everything works well, both applications work fine.But if i change the address location of the CM0 from 0x08020000 to 0x08027800, the the CM0 doesn't work, only CM4.The STM32WL55JCIX_FLASH.ld of CM0:system_stm32wlxx.cDoes anyone have an idea what is wrong?

Hi, I'm setting up a custom board with STM32G431CBT6 to control a 6-step bldc motor. I want to use comparators to protect against overcurrent.My problem I configured the bkin input and comparators. the bkin input works, the comparator also works separately (puts out an external signal). But the PWM does not stop when the comparator is working. I can see the active output of the comparator, but it has no effect on the pwm.I created a simple program to test this, no motor control, just complementary PWM.I want it to work at the hardware level. Can someone tell me what I'm doing wrong?I add screenshots and code.MX_GPIO_Init(); MX_TIM1_Init(); MX_COMP1_Init(); MX_DAC1_Init(); /* USER CODE BEGIN 2 */   HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1); HAL_TIMEx_PWMN_Start( &htim1, TIM_CHANNEL_1 );   HAL_COMP_Start(&hcomp1);   HAL_DAC_SetValue(&hdac1, DAC_CHANNEL_2, DAC_ALIGN_12B_R, 4000); HAL_DAC_Start(&hdac1, DAC1_CHANNEL_2);   HAL_DAC_SetValue(&am
