For RF access, if the requested read is entirely within a locked area, the document shows that both device variants will give an error: But the document doesn't show the corresponding case for I2C - it only shows the case where part of the requested range is locked:So what happens in the case where the requested read is entirely within a locked area?Is there a specific error returned? Or does the entire read give FFs? Or what? What is the recommended way to detect that a read has failed due to locking?ie, how do we know if its genuine FF data, or just FF due to locking?

I try to add external loader to C:\ST\STM32CubeIDE_1.8.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.0.100.202110141430\tools\bin\ExternalLoaderIn debug configuration, check ExternalLodaer and than press Scan.The scan fail with message "Failed to list external Loader"If I remove the external loader that I added the scan work fine.The exetrnal loader that I try to add is MX25L6433F_GFX01M2_STM32G0.stldr from X-CUBE-DISPLAY pack.STM32CubeIDE Version: 1.8.0

Short and simple question: Why am I getting this error? Is there something obviously wrong with the schematic?Tested all possible configurations when trying to connect. Holding boot, holding reset, nothing works. The error code changes to target not found when the supply is removed from the MCU.All the voltages around the MCU on the capacitors are right. All capacitors are near the BGA. VDDPA is 1.5V, all VDD pins are 3.3V. There is one thing which bothers me. The vref+ pin is not connected. The datasheet mentions this Pin to be connected to VDDA or Ground, nothing about a floating state. Is it impossible to flash the device when the vref+ pin is floating? Because this is the only problem i can find at the moment.Note. I have access to an X-Ray and all the pins seem to be connected properly.Thanks in advance.

Hi,When debugging with Cube IDE programs without any TouchGFX graphics load quickly using the debugger typically 20 to 30 seconds. When TouchGFX is used such that the NOR Quad SPI Flash has to load the loading time can easily exceed 3 minutes. With only a singles simple screen it takes ~60 seconds.I assumed that if nothing is changes in the graphics from one debug session to another then there would be no changes required in the external graphics flash and so the loading of this memory is unnecessary after it has been loaded once.I therefore turned off the external loaded in the debugger setup:However when I tried this I got the following error:Error in final launch sequence:   Failed to execute MI command: load G:\\ShorttG2\\ShorttG2\\STM32CubeIDE\\Debug\\STM32H7B3I_DISCO.elf   Error message from debugger back end: Load failed Failed to execute MI command: load G:\\ShorttG2\\ShorttG2\\STM32CubeIDE\\Debug\\STM32H7B3I_DISCO.elf   Error message from debugger back end: Lo

Just wondering if ST provides a SPICE library for the TS985 comparator? I haven't used many parts from ST and could help with any advice. My goal would be to simulate the comparator within LTSpice.Thanks,Alan

Is there any code example on how to perform the VBAT/3 measurement. I need to measure my battery level (1.8V-2.7V) which I connect to VBAT pin. VDD and the rest of the micro supply pins are coneccted to a DCDC output which gives 3.3V.

What is the capacitance IO of HSE and LSE?

Good morning everyone,I'm facing some trouble compiling a project made by SPC5STUDIO 5.8.1 the project is configured by written makefile and rule.mk file.I tried with the last release (V6) and it's not working after importing the project (I did save after the configuration.xml was updated by the spc5studio ), I have compiling errors make:ex: *** No rule to make target 'LINIF.c', needed by '/obj/LINIF.o'. Stop.I guess there's some procedure to follow in order to upgrade the SPC5 studio configuration.xml file in order to make it work.I would like to try with the previous version of spc5Studio but I couldn't find a way to download it , could someone share a link for that version?Thank you.

Hello,I'd like to erase and load an hex file on a STM32 without use the STM32CubeProgrammer as interface. Is it possible integrate the ST-LINK v2 (SWD interface) functionality in a python/C# script to automatize the erase/flashing and integrate it with the rest of the EOL test.If ST-LINK is not suitable can you suggest a different way to implement my goal ?Regards,Riccardo

I have tested Power On Reset / Power Down Reset (POR/PDR) voltage threshold on two STM32G070RBT6 sourced by different suppliers. The threshold isn't matching the specified voltage 2.06<VPOR<2.14 and 1.96<VPDR<2.04 but it fits values stated in STM32G081 datasheet, 1.62<VPOR<1.70 and 1.60<VPDR<1.69. The brownout reset feature is functional on both STM32G070 and STM32G081 but it's not available on STM32G070 according to spec. I looks like STM32G070 uses the same silicon as STM32G081. Thus I'm concerning what to expect from different batches of STM32G070, can we relly on spec or rather consider STM32G070 to be equal with STM32G081.

Hello, i designed a PCB with footprint for st25dv04k and antenna, I connected the 2 antenna port to the IC chip.The antenna is 10mm X 50mm, 6 loops, a width of 0.15mm and 0.15mm pitch.The antenna inductance L is 2.5uH according to tag capacitance.I soldered the tag, fairly but it seems that I couldn't detect it with any rfid/nfc reader.I attached the PCB picture, can you help detect what is the problem?

Dear,on STM32L083 I use internal eeprom. I found out, that when I use functionHAL_FLASHEx_DATAEEPROM_Programand during execution of this function the power voltage of mcu falls down (uplugged battery from device) - then in eeprom are saved wrong data (probably only in sectors which I wanted to modify by calling the function above).I use BOR Level1. Also I tried to activate PVD and in its IRQ callbacks I just added while(1); until the mcu goes to reset.Is there any solution for that? Thank you very much, Jan.

To reduce latency time of interruptions.Based on the same thing but in stm32f0 devices

currently using stm32f105 (HSI+PLL) ,and i am trying to clock faster than 36MhzThey are from the same stm32 familly, why is the PLL of the stm32f105 limited I am using CubeMX 6.4.0

I've downloaded STM32Cube_FW_L4_V1.17.0.However in this package, there is no project code for B-L462E-CELL1, of which the MCU is an STM32L462REY6TR microcontroller. Particularly I am looking for sample code for USART communications.

Hi, I am working on STM32f413zh and I am referring https://www.mikrocontroller.net/articles/STM32_BLDC_Control_with_HALL_SensorIn my code shows TIM_SelectOutputTrigger() not defined. There is no definition for some timer related functions.Please give me the guidance.Thankyou

I'm running the latest (less than one week old) macOS Monterey developer beta 12.4 (build 21F5063e) on a MacBook Pro 10,1 and downloaded the file en.st-stm32cubeide_1.9.0_12015_20220302_0855_x86_64.dmg_v1.9.0.zip, decompressed and installed the app. But attempting to start the app causes a hiccup in the macOS first-time verification of the app and produces the following error:Notes:Anti-virus software can corrupt downloads. I disabled Avast file and web checking.I tried this download multiple times; same result.Other tools, e.g., MX and Programmer, downloaded, installed and run OK.Has anyone else seen this? Recommendations?TIA,Mike

Hello, there is posibility we mixed STM8L101F3 vs F3U. There is marking L1S3 on the top, but I can't find any information/table of these markings. Is is possible to have it ?

We have a custom board with and STM32MP153CAA processor and are trying to get it to boot from an SMCC card on SDMMC2 interface. If I loaded the tf and fip files via a UART I am able to get u-boot running and then use the "run bootcmd_mmc0" to boot the linux kernel from the SDMMC2 car from there. So I know that the electrical connection to the SD card is correct. However we'd like to have the whole boot process read from the card at power up.I have an SD card laid out with the partition scheme used to boot the discovery boards from SDMMC1 and have written the boot loaders to the card. I have tried setting the OTP word 3 to 0x10 which from ST's documentation I would believe should set up the boot from the SDMMC2 card and have set the boot pins to 101 binary which should tell the processor that the primary boot should be from SDMMC card, but if will not boot. I get nothing at all output to UART-4 which I have set up as console nor any indication that the board is trying to read from
