Hi,My setup:SP570S-DISP Demo Board EvaluationuC: SPC570S50E1IDE: SPC5Studio 5.8.1I'm using example "SPC570Sxx_RLA Bootloader Application for Discovery".Function "updater_jump()" In "firmware_updater.c" file, jump to application image without checking if there is valid application image.So, if there isn't a valid application image, bootloader stucks and the only way to restore bootloader functionality is to perform a "physical" reset using button RESET of SPC570S-DISP board.void updater_jump(void) { void (*fptr)(void); uint32_t jump_address_pointer; vuint32_t jump_address;   jump_address_pointer = updater_config.codeimage1.address + 4UL; jump_address = *((vuint32_t*)(jump_address_pointer)); /* * stop peripherals */ #if (SPC5_UPDATER_CONN == SPC5_UPDATER_CONN_CAN) can_lld_stop (updater_config.can_driver);   #else sd_lld_stop(updater_config.serial_driver); #endif #if (SPC5_UPDATER_ACT == SPC5_UPDATER_ACT_TIMER) stm_lld_stop(updater_config.stm_driver); #endif   u

In 'X-CUBE-NFC6', I found the prefix code of NFCID2 in SENSF_RES is '0x02, 0xFE'. But the IS​O 18092 says:The 6-byte number shall be randomly generated while the prefix code is ‘01’ ‘FE’. Other settings for the prefix code are RFU.So, what's the meaning of '0x02, 0xFE' here?

Posted on October 11, 2017 at 15:09In summer 2017, I started an project with the STM32F767 on the Nucleo board, because the H743 was still announced but not available. For some weeks I got the new Nucleo board of the STM32H743. After I transferred the code from the F767 to the H743, I recognized the not working DMA interrupt. The DMA interrupt was working on the 767 perfectly. So I reduced the code of the F767 and the H743 (by using cube) to only this function for see what�s the difference. TIM3 managed 4 PWM Signals (22KHz) and triggers the ADC1 on falling edge and call the interrupt call back function. (LED GREEN toggles).When ADC1 conversion is finished, the DMA is triggered and copies the data.When the DMA transfer is completed, the call back function is called, and the BLUE LED togglesI can�t see, why the interrupt for the DMA at the STM32H743 is not working! Have somebody done something like this already and was successful?I put both projects for Cube and the AC6 workbench to th

Hello, I’m working on device equipped with STM32H753 and LCD (320x240), 16 MiB of SDRAM (available for caching will be about 13 MiB) and SD card (SDMMC interface) that will be used also for storing images for TouchGFX.In some cases device shall display a few animations. Initially we’ve thought that animation will be stored as sequence of .PNGs and use of AnimatedImage widget. Amount of images depends in given animation, but let say that will be a at least one thousand of PNGs. After loading almost all PNGs and “indexing�? by TouchGFX Designer it slowed down to unusable state. Source files (.cpp) generated for images had size about 2.5 GB. We wanted that TouchGFX will be aware of each .PNG to generate IDs and use each for caching (we think that not all images will fit into SDRAM to accomplish full caching). The second reason for doing in that way was a unified procedure to extract binary with bitmaps and use it for external loader (TGX uses specific linker section for all images).After

Hi all,I'm developing a custom board based on STM32MP153 SoC, and I need to use the internal RTC. I also need to output its 32.768kHz reference clock from I8 pin.As stated at https://wiki.st.com/stm32mpu/wiki/RTC_device_tree_configuration, into the Linux dts I enabled the internal RTC using this node:&rtc { st,lsco = <RTC_OUT2_RMP>; pinctrl-0 = <&rtc_out2_rmp_pins_a>; pinctrl-names = "default"; status = "okay"; };but at the boot I get this log message:stm32_rtc 5c004000.rtc: Can't enter in init mode. Prescaler config failed. stm32_rtc: probe of 5c004000.rtc failed with error -110The driver is not loaded, thus I don't have the 32.768kHz clock on I8 pin.Could you help me to figure out what I'm doing wrong?Thanks in advance, regardsMauro

Hi,I am using STM32G474 th STM32CubeIDE and I want to implement the break function for TIM1.When I configure the pin PA6 in the pinout view as TIM1_BKIN I expect that the port will be automatically configured as input, but after I checked in the GPIO configuration of the TIM1 I see that the pin was configured as Alternate Function Open Drain.Why is that happening?And if I try to configure it manually in the MX_GPIO_Init() function, my code is, obviously removed.What should I do?Thanks!!Daniel

I tried to use CMSIS DSP library for FFT implementation on STM32F407. I based my project on Tilen MaJerle library. I sample data with on board ADC and fill the input buffer with function TM_FFT_AddToBuffer(TM_FFT_F32_t* FFT, float32_t sampleValue). Hereafter I process data with function TM_FFT_Process_F32(TM_FFT_F32_t* FFT). uint8_t TM_FFT_AddToBuffer(TM_FFT_F32_t* FFT, float32_t sampleValue) {   /* Check if memory available */  if (FFT->Count < FFT->FFT_Size) {  /* Add to buffer, real part */  FFT->Input[2 * FFT->Count] = sampleValue;   /* Imaginary part set to 0 */  FFT->Input[2 * FFT->Count + 1] = 0; /* Increase count */  FFT->Count++;  }   /* Check if buffer full */  if (FFT->Count >= FFT->FFT_Size) {  /* Buffer full, samples ready to be calculated */  return 1;  }   /* Buffer not full yet */  return 0;  }     void TM_FFT_Process_F32(T

Hello,I am developing an app using tortoise git, I have made a lot of commit and cleanup in rep and my application was ok.Ten commits ago I never made a clean up, so, when I cleaned up the repository my app crash in one line of code I made before.I am working with keil, I had clicked "generate code" in designer and then open keil and compile, but it crash in certain cases.The app is working 70% before I cleaned up git it was 100%.I really need urgent help.Thanks

Hi everyone,I have a problem about the integration of the SEGGER embOS RTOS with SBSFU.I have already succeeded with FreeRTOS but I would like to use embOS for my project. The "SECoreBin" project compiles well, I added the instruction to deactivate the systick in the SBSFU project just after "SFU_LL_SB_SRAM_Erase ();".When I run my "user app" project my interrupt "systick_handle" does not work.Have you ever used embOS with SBSFU ? Do you have any advice ?I've been struggling with this problem for several days now :(Best regards, Hugo

Hi,I am working on a custom board using the STM32F479NI.I have been able to use EXTI on the PC7 without problems.Now I need to implement it on PE2.But this time, the EXTI2_IRQHandler is being called over and over without any electrical changes on that pin.The schematic for that pin is very simple (one pull-up and a protection diode, Button is connected to PE2) : I am using STM32CubeMx to generate all the necessary code :And I made sure to call the MX_GPIO_Init() function.Right after calling the MX_GPIO_Init(), the EXTI2_IRQHandler is called over and over.I also made sure that the interrupt is being cleared, this is done in the CubeMx generated code in the function HAL_GPIO_EXTI_IRQHandler :The callstack looks like this :I did not modify any of the CubeMx generated code, so the EXTI2_IRQHandler and HAL_GPIO_EXTI_IRQHandler are the default one.Please note that when using PE2 as a GPIO_Input, and pooling it, I do not see the issue.I also noticed that the voltage at this pin is dropping wh

Hello, everyone!I am a user of STM32H753. I want to run two programs within STM32H753 and exchange the values ​​of the variables between these two programs. (Program 1 is running on Flash memory bank 1 sector 0; Program 2 is running on Flash memory bank 2 sector 0.)For reference, I use STM32CubeIDE 1.3.0 as a compile tool.In the past, when IAR was used, two variables in the program were placed in the same address in the noinit area, and after changing the compilation tool to STM32CubeIDE, I do not know what to do.What is the

Posted on March 01, 2018 at 14:28That is anoying. STM32CubeProgrammer does not work in DFU mode and Its probably a driver problem. On Page 7/39 in UM2237 STM32CubeProgrammer software description - DFU Driver. There it is described to uninstall the old 'STM32 DFU Device driver' for DfuSe. Which i Did by deleting the driver in Windows Hardware Manager by right click - deinstall - delete all driver files. Then as descibed i ran the “STM32 Bootloader.bat� file as admin.After that reconnected STM32 (any nucleo board) in DFU Mode but still the old 'STM Device in DFU Mode' like in Figure 1 on page 7/39 gots installed and not the STM32_Programmer Driver driver like in Figure 2 page 7/39Therefore STM32Cube Programmer does not connect to any uController in DFU modeSo how can i make a clean uninstall of your the old DFU driver?Thaks STM for your help in advance

I am attempting to debug my firmware for a STM32L452xx chip, which is programmed in at the memory address 0x08010000. The bootloader will be placed at 0x08000000, but at the moment the memory is empty. Is it possible to trick the debugger so it always starts at main for the firmware in the debugger i.e. somewhere after 0x08010000 memory address? I changed the IROM1 address, as well as the FLASH_BASE address in the HAL so the vector table is configured correctly. I am just struggling with the debugger aspect of running to main on the entrance to the debugger. I "think" I need to set the MSP pointer when i enter the debugger to a specific memory address, but I am unsure. Also am unsure if I need to do something else.I've already written a couple other bootloaders for different stm32 chips, but I've never gotten over the hump to be able to debug the firmware from a non-top memory address. I usually need to change the address settings before trying to debug. Hoping someone will tell me I a

I want to register the MAC address of my own board which STM32MP151CAA3 is mounted on.Can I use STM32CubeProgrammer to register the MAC address?If so, are the following commands correct?​ Example) MAC address which I want to register: 00:12:34:56:78:90​ > STM32_Programmer_CLI -c port=usb1 -otp program wordID=0x39 value=0x56341200 > STM32_Programmer_CLI -c port=usb1 -otp program wordID=0x3A value=0x00009078Also, can I update this OTP bits only once?(If I register the MAC address once, Can't I update it again?)​Best regardsH.

Hi all,​I've met a weird issue, when using STM32F446VET chip to connect PC by USB, and PC alerts 'USB can't be recognized'.​I've go throught some related topics on the forum, but unfortunately all didn't help. For example,1) disable VBUS sensing2) increase stack and heap size to 0x2000 or even 0x10000 .3) since the board is powered by USB, and STM32F446VET doesn't have VBUS pin. I've tried to add an external pull-up 1.5KΩ resistance4) make sure USB clock is 48MHZ​When i try to inspect the code(STM32F446ZE-Nucleo example of STM32Cube_FW_F4_V1.25.0 package, downloaded from ST website), I found some other strange phenomenons: 1). the core provides USBRESET and ENUMDONE interrupts, but no OEPINT and IEPINT interrupts at all2). the USB code provides RXF_LVL interrupt in OTG_GINTSTAT, but OTG_GRXSTSP remains 0, and OTG_DOEPTSIZ0 is 0x60080018(PKTCNT field is 1, indicating no packet is written into RX FIFO)​Has anybody met or solved similar question, or any other suggestion is really apprecia

Hello,I have a GUI, that is also combined with another tasks in the project.So we have some custom includes in the code of GUI. I wonder if we are able to check this GUI also in simulator. When I try to run Simulator, it complains about missing custom files in include statements...Can I just somehow solve, because I'd only like to try the TouchGFX part of the project.Is there any more info on how Simulator builds ?Thanks in advance,Regards,B.

Is it possible to implement touchgfx with a NUCLEO board. I think yes because my NUCLEO STM32F767NI has LTDC.But i doubt because the aren't touchgfx templates for nucleo boards.

hi,slowly slowly i've got my growing TouchGFX project to become too fat for the2MB flash on a STM32F429..as i've put too much graphic assets on the "database" and i'm not using all of them in the screens, i'm wondering if there's a way to find out "programmatically" which assets are not really referenced.. ( i know which "few" icons i put up with a routine..)i only found this thread, 4 year old, that's really shows a manual procedure (and tedious..) =)https://touchgfx.zendesk.com/hc/en-us/community/posts/207462585-Removing-unused-bitmapthanx for hints!

I want to make freeRTOS touchgfx on simulator (GUITask, TransDataTask). Does TouchGFX support for freeRTOS on simulator?Please help me. Thanks
