Hey guys,Having some issues with running through the kernel setup and dont understand the errors returned back as iv followed all the steps to a T.Attached my terminal history. This in on the https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Modify,_rebuild_and_reload_the_Linux%C2%AE_kernelI honestly dont understand what i may have done wrong here. if possible id like to understand the method to understanding errors within linux as this is my first ish run with native linux installed Also to note i did have a look at the readmes within the file system to which i think they differ slightly to whats whats on the wiki.Error:andreas@andreas-desktop:~/STM32MPU_workspace/STM32MP15-Ecosystem-v3.0.0/Developer-Package/en.SOURCES-kernel-stm32mp1-openstlinux-5.10-dunfell-mp1-21-03-31/stm32mp1-openstlinux-5.10-dunfell-mp1-21-03-31/sources/arm-ostl-linux-gnueabi/linux-stm32mp-5.10.10-r0/linux-5.10.10$ make -j2 ARCH=arm modules&nbs

I have a low frequency (~1 kHz), low duty cycle signal that I'd like to capture rising edges of. What's the minimum width of those pulses to capture them using a timer in input capture mode?I see there's a programmable digital filter there, in terms of fDTS and ***_INT, and that the latter is the respective APB bus clock (but divided by no more than 2 from SYSCLK). But what dictates fDTS?

HelloI designed a card with STM32L052C6T6 mcu, but I can't find this mcu in Turkey.What would you recommend as a pin to pin instead..I found stm32f103c8t6 but if anyone else please advise

Hello Our STM32G4 is measuring a sinus-ADC value with offset. The offset is at VDDA/2.Our ADC measurement shows a plateau at the offset, even, when the sinus signal is crossing the VDDA/2 (see attached picture).The signal them self seems to be ok (measured by a KO).Is there an ADC issue? Any hint, what this could be effected?Settings from the ADC not ok?thanks for your reply

Hi!I wrote a Unscented Kalman Filter for the VL6180x sensorhttps://github.com/DanielMartensson/Unscented-Kalman-FilterIt works great! Better accuarcy. I have customers that want STM time of flight sensors but they telling me that "The angle is too big and the laser light is too weak, can you find ToF laser sensors that have FOV angle less than 10° and a little bit stronger laser light for darker places".So I'm asking the STM support if STM have laser sensors that have the same accuracy as VL6180 and range (0-60cm) or VL6180 with the range (0-20cm) but with lower FOV-angle?FOV angle at 25 is too much if I want to measure small objects at a distance.

Dear Team,We are using VL53l1X in our application to detect people leaving and entry, we got 5 vl53l1x breakout boards from one of my distributors for prototyping.People count programming working without any issues when using it in polling/continuous mode, but for power optimization we want to use an interrupt method, Count increment and decrement should happen when there is an interrupt, rest of the time the main controller and other things to be in sleep mode.Took code from -> en.STSW-IMG010.zipPolling method works fine herePlayed with ROI, timing budget as per my application everything works fineModified the given code for interrupt method, we are getting interrupt but we are getting wrong path most of the time and wrong count.Here is the code...//Event CallBack void interrupt_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action){   nrf_drv_gpiote_in_event_disable(INTERRUPT_PIN);   event = true;   printf("Event occured\n

I put a group of same small custom containers inside a large container. Then I added this large container to my view. How can I propagate button callback from small container to current view and also identify which small container triggers the callback?

I have a problem with a couple of BLUENRG-M2SP modules. I tried flashing the firmware under linux (We have to flash 100+ devices and each device needs a different firmware so plug and play flashing is not sufficient enough, so I copied ST's config from the flasher utility) and the operation failed with the following error message: 'Error: Erase command failed (timeout)'. So I tried flashing with ST's BlueNRG-X Flasher Utility 4.1.0 But I got the same error.Here are some logs:******FLASH OPERATION******   Flash of n.1 device connected by SWD (ST-Link/V2, CMSIS-DAP, J-Link)   18:32:11.640: Device connection by ST-Link/V2 -> Device connected 18:32:12.335: Device Identification -> BlueNRG-2 18:32:13.023: Device Flash Programming -> FAILED 18:32:14.298: Device Disconnection -> SUCCESS   18:32:15.016: Flash operation finished!     ******END FLASH OPERATION******debug_level: 2   4000 4445 C:/flasherUtilityTemp/BLE_Beacon_truestudi.bin 0 0028002E315650

Hi Could any one please tell me the difference between ST24DV04K & ST25DV04KC chips?In datasheet for KC , it says that it is Version-C in part ordering infoBoth ICs seem to work from 1.8 V to 5.5VWhat am I missing here?Kind regards

I am using eMMC memory with a STM32F769NI controller. For programming this eMMC I've written an external loader in STM32CubeIDE. My loader works fine with STM32CubePogrammer, but I also want to be able to debug my application from CubeIDE. How can I tell IDE to use my loader? There is a setting "External Loader" in "Debug Cofigurations", but it does not allow you to select your own file, it only has a button "Scan", that lets you choose an external loader from a drop-down list. I don't know how to add new loaders to that list. Does anyone have an idea how to do that?

Hi,I would like to report 2 possible bugs on the rfalST25xVPollerWriteMessage implementation:The msgLen parameter must be "number of Data bytes minus 1", as a direct translation from the "Write message" command, but msgLen == 0 is not accepted as valid (rfal_st25xv.c line 205), failing to write 1 byte-long messages, which according to the ST25DV datasheet should be OK.The required TX buffer len (calculated on line 202, and checked on line 205), considers 2 bytes for the msgLen parameter, but this parameter is only 1 byte long, preventing from using buffers that are the exact (and correct) number of bytes long.Best RegardsGustavo

Hi,I am working on STM32H745 discovery board and trying to configure the onboard 4GB eMMC flash over SDHC1 interface. I am loading default discovery board configuration by the CubeMx configuration, which sets both M7 and M4 and all AHB buses to run at 64MHz (STM32H7 CubeMx Repository v1.8.0).I am configuring the SDMMC peripheral clock to 200MHz and setting clockdiv to 4, this will provide 25MHz clock to the eMMC. My application is running on M7. I want to utilize the IDMA for read/write and using HAL_MMC_ReadBlocks_DMA and HAL_MMC_WriteBlocks_DMA APIs. By using this configuration, the DMA interrupts are resulting in Rx Overrun and Tx Underrun errors.I ran the MMC/DMA example for the discovery board which sets eMMC clock to 50MHz, M7 at 400MHz, M4 at 200MHz. The HCLK for D1 Domain AXI and AHB3 peripherals , D2 Domain AHB1/AHB2 peripherals and D3 Domain AHB4 peripherals at 200MHz.The APB clock dividers for D1 Domain APB3 peripherals, D2 Domain APB1 and APB2 peripherals and D3 Domain

Saludos!Im new to STM32W series.With two P-NUCLEO-WB55 boards on my table im trying to run the BLE_CableReplacement example.It doesnt work out of the box so i opened the readme.txt @par How to use it ?   This application requires having the stm32wb5x_BLE_Stack_full_fw.bin binary flashed on the Wireless Coprocessor. If it is not the case, you need to use STM32CubeProgrammer to load the appropriate binary. All available binaries are located under /Projects/STM32_Copro_Wireless_Binaries directory. Refer to UM2237 to learn how to use/install STM32CubeProgrammer. Refer to /Projects/STM32_Copro_Wireless_Binaries/ReleaseNote.html for the detailed procedure to change the Wireless Coprocessor binary.I found the binaries already But as i try to follow the release note instructions i get stuck in STEP3 There is no "Start FUS" button anywhere, am i doing the raindance wrong?Also if i try to "firmware upgrade" anyway is asking me for the start flash addr, thats not in any STEP

Hi Sir,We have used the LSM6DS3 part in our application boards. Now the distributor mentioned LSM6DS3 part ha end of life and New part is LSM6DSL.Please confirm this new LSM6DSL part is pin to pin and firmware side compatible with the LSM6DS3 part. Or please share changes .RegardsAnees PK

Hello everyone,I would really like to use the X-NUCLEO-NFC06A1 expansion board in order to transmit power wireless. I read that it should be able to transmit 1.6W of power. At the moment I used the NFC06A1 available library to power up the board. In particular I called the rfalNfcInitialize(), rfalNfcDiscover() and rfalFieldOnAndStartGT(), functions. This way I am able to see that the antennas are functioning properly, but i did some testing and it seems like i can only get very few mA from a receiving antenna.Which is the best way to initialize the board in order to deliver maximum power (regarderless of circumstances)?Thank you very much.

Hello all, my company has decided to use the STM32L03 series for a simple ISO ​14443-3 tag reader, and we underestimated how much memory the full rfal takes up. Can anyone help me find an easier way to cut down the provided polling demo into 16k flash or less? I can scrap all other tag types except the T2T /nfc-a, and I only need read functionality. I am slowly working through and trimming the fat, but if there's a smarter way to limit program memory I'd be very thankful.

The MX generated C code issues the USART initiation call before the DMA initiation call. My code simply echoes back any text received by the USART. Unfortunately the echoed data (correct length) is all zeros. The UART read buffer is initialised with zeros.The issue is resolved by simply placing the DMA initiation call before the USART initiation call!What’s going on? Looks like the DMA code upsets something set by the USART code, but what?

Of the many things I have been struggling withmSTM32MP157F-DK2 throughout this summer, one of them is the interprocessor communication between A7 and M4. I want A7 to process data and send the refined result to M4 for further low level actions. As many users may agree, information in this wiki is scattered with many branches, and while following one topic you encounter references to many links that end up blowing you out if the device is new to you. I am one blown out that way.I was reading this post https://wiki.st.com/stm32mpu/wiki/Coprocessor_resource_table and found that I have to have this code somewher in my M4 firwarewhich I managed (by trial and error) to add in my rsc_table.c as (note sure if that was correct) Then found rhat I also have to add this code somewhere, but not sure where: whether it is in A7 Linux userland or in M4 firware. Played around many times for over 14 hours and got frustrated.can anyone help me? 

The gcc variant in STM32MPU Embedded Software distribution components is 'arm-ostl-linux-gnueabi-gcc'. Then what's the difference between 'arm-ostl-linux-gnueabi-gcc' and 'arm-none-linux-gnueabi-gcc'?Thanks.

The datasheet (https://www.st.com/resource/en/datasheet/st25dv16k.pdf) states that "The impedance on LDP pin when set high doesn't exceed 5kΩ.", which means that a lot of power is wasted just signalling the IC to power down. Am I interpreting this wrong or is the datasheet wrong?
