Hi. When I call HAL_NVIC_SystemReset(); or NVIC_SystemReset(); the system just freezes up instead of restarting. I figured forget about it and moved on to try out the watchdog, well the same thing happens. Watchdog is enabled and working fine, then I enter an infinite loop to try it and after it times out the whole chip gets stuck.I don't know why this is :(

I update my Stm32CubeMX to 5.0, and open an old project , regenerate the code with ToolChain SW4STM32I have some floder missing, I must recreate the floder and copy the files into it.The old version of Stm32CubeMX is OK.Is there a solution?

We are building a 115kHz SMPS transformer that is being used in a circuit using a VIPER06HS. It is in the circuit with my transformer that is outputting 5 volts at 200mA the OCP is tripping off the VIPER unit. I would like to know how the OCP works. If my transformer was oversaturating would that cause the OCP to trip?NOTE: This question and answer originated from a customer support case which was handled by us.

Hiwith STM32CubeMX 5.1.0 on STM32F746BGTx there is an issue when I enable RS485.Cube doesn't genrate all funtions related to RS485, for example the main inizialization function HAL_RS485Ex_Init is not present in the code generated by Cuce.Attached the simple project file that generate the issue.Best regard.Gianluca Costa

I have a question for the configuration of the static registers via the I2C bus.The easiest way to configure the Area RF protection and Area ending point registers, (address 0x0004 until 0x000A), is to send a I2C write message to program all 7 data bytes in one I2See the table 11 snapshot from the datasheet:However, data is not programmed. Any suggestion why it does not work?NOTE: This question and answer originated from a customer support case which was handled by us.

Hello,I have a very weird behavior...When trying to access external synchronous PSRAM.I see the clock and cs change only if I stop and starts stepping inside the while(1) loop below. When doing "go", there is no clock nor CS changes.I tried to add delays as you can see, but nothing helps.#define FPGA_BANK_ADDR 0x64000000   __IO uint8_t value; __IO uint8_t * volatile psramaddress = (__IO uint8_t volatile*)FPGA_BANK_ADDR+2; while(1) { *psramaddress = value++; rd_2 = *psramaddress ; HAL_Delay(500); }Is there any idea ?Thanks

Prefer to have versions older than the STM32CubeF3 v1.10.0 release. Scot over to the website to see if they have options to download previous versions but to no success. Please help!

How can I locate array in SRAM instead of DTCM RAM(128kB)?uint16_t array[320*240] is overflowed in H743ZI.Sytem workbench says <DTCMRAM overflowed by 25760 bytes>.I don't have any trouble with F429ZI.

I downloaded Yocto_SDK Software Version- 1.0.0 for STM32MP151C. The environment setup file name is - "environment-setup-cortexa7t2hf-neon-vfpv4-openstlinux_weston-linux-gnueabi". Does it mean that this SDK is tailored for Wayland implementation? We intend to use raw framebuffer device. As of now we have no plans of using X11 or Wayland. Can we use this SDK?

Hi,I have stucked trying to use hrtim pwm outputs on stm32f334r8.I use initialisation provided by CubeMX to start all 10 channels right now. I use exactly the same setting for every channel, but still have different results.It is not possible to fit init code here, but here the main parts://TIMER CONFIG START pTimeBaseCfg.Period = 0x0960; pTimeBaseCfg.RepetitionCounter = 0x00; pTimeBaseCfg.PrescalerRatio = HRTIM_PRESCALERRATIO_DIV1; pTimeBaseCfg.Mode = HRTIM_MODE_CONTINUOUS; //WAVEFORM TIMER CONFIG START pTimerCfg.InterruptRequests = HRTIM_TIM_IT_NONE; pTimerCfg.DMARequests = HRTIM_TIM_DMA_NONE; pTimerCfg.DMASrcAddress = 0x0000; pTimerCfg.DMADstAddress = 0x0000; pTimerCfg.DMASize = 0x1; pTimerCfg.PushPull = HRTIM_TIMPUSHPULLMODE_DISABLED; pTimerCfg.FaultEnable = HRTIM_TIMFAULTENABLE_NONE; pTimerCfg.FaultLock = HRTIM_TIMFAULTLOCK_READWRITE; pTimerCfg.DeadTimeInsertion = HRTIM_TIMDEADTIMEINSERTION_ENABLED; pTimerCfg.DelayedProtectionMode = HRTIM_TIMER_A_B_C_DELAYEDPROTECTI

In stm32l1xx_ll_rtc.h, generated by STM32Cube MCU Package for STM32L1 Series, v1.8.1, line 2110:__STATIC_INLINE void LL_RTC_ALMB_SetDay(RTC_TypeDef *RTCx, uint32_t Day) { MODIFY_REG(RTC->ALRMBR, (RTC_ALRMBR_DT | RTC_ALRMBR_DU), (((Day & 0xF0U) << (RTC_ALRMBR_DT_Pos - 4U)) | ((Day & 0x0FU) << RTC_ALRMBR_DU_Pos))); }The first argument of MODIFY_REG() should be RTCx->ALRMBR, not RTC->ALRMBR.I think :)

Does this processor have a max size limit on stack frames? (as opposed to max size of total stack). The stack frame size is the amount of stack space set aside when a function calls another function (this is mainly composed of local variables declared in the called function).

Hello,until now, all STM32 datasheets do not specify JTAG/SWD interface characteristics except for STM32H7: 6.3.33 JTAG/SWD interface characteristics.The JTAG/SWD interface characteristics should be specified.

When setting the primary slave address for I2C in cubeMX for the STM32F1xxThe generated code will be the address * 2. This created address is incorrect. The address should not be multiplied by 2.for example: Set I2c Slave address to 0x50Generated code sets the OwnAddress to : 160. which is (0x50 * 2)The st does not response to the address 0x50, because the ownAddress is set to another value.

I'm working on a low power driver for our project and want to put the mcu into sleep mode to be woken up by a timer. The mcu enters the Sleep mode but does not exit from the same. Since I have the Seggar J-link connected to over a JTAG port for debug, I can see that the RTC Alarm call back is being serviced and prints out the debugging information but the mcu does not exit the sleep mode. Here is the code. void PMODE_EnterSleep(void) { HAL_PWR_EnableSleepOnExit();   HAL_SuspendTick();   // Request to enter STOP PMODE with regulator in low power PMODE HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI); }     void PMODE_ExitSleep(void) { HAL_PWR_DisableSleepOnExit();   SWD_PRINTF("Exiting Sleep\n"); }   // .... A general power mode servicing module   void PMODE_ServicePower(PMODE_eOperatingMode_t eModeToEnter) { switch (eModeToEnter) { case PMODE_eRun: break;   case PMODE_eSleep: SWD_PRINTF("Sleep\n"); PMODE_Enter

We would like to use the embedded STM32 in the SPIN for calculation purposes if no Vm power supply voltage is available.But datasheet is mentioning that Vdd < Vm. And the circuit diagram shows connections between Vdd, Vdda and internal 3.3V.Question 1: Is it possible to use only Vdd and Vdda (both 3.3V) to run the chip ?Question 2: Under this condition which max. input current we would have to expect if CPU runs in low power mode ?NOTE: This question and answer originated from a customer support case which was handled by us.

We are using the SPC560B54L3 MCU in our project. After initial testing we found that the startup time is very high (about 235ms from powering the controller to the start of the application main function). From the documentation it is not clear how much time it takes the controller to start typically. Our application is initializing all the SRAM on the target in its startup code. Any advice from your side?NOTE: This question and answer originated from a customer support case which was handled by us.

Hello,I have a little confusion regarding FMC memory map. I hope someone can help me with it.Accoring to reference (stm32h743) FMC external memories are mapped as following:0x6C000000 -0x6FFFFFFF FMC NOR/PSRAM/SRAM 4 Bank1 (or remap of FMC SDRAM Bank1)   0x68000000 -0x6BFFFFFF FMC NOR/PSRAM/SRAM 3 Bank1 (or remap of FMC SDRAM Bank1)   0x64000000 -0x67FFFFFF FMC NOR/PSRAM/SRAM 2 Bank1 (or remap of FMC SDRAM Bank1)   0x60000000 -0x63FFFFFF FMC NOR/PSRAM/SRAM 1 Bank1 (or remap of FMC SDRAM Bank1)NOR is mapped to first bank (0x60000000), does it mean that we can access it only from 0x60000000 -0x63FFFFFF ?I see in NOR datasheet that it has 128M Bytes size which mean that only half of it can be addressed using this memory addresses above...Does it make sense ?Thanks you,ran

Is there a HAL method that allows you to easily set a transmit DMA interrupt like "HAL_UART_Transmit_DMA(...)" but without setting the half transfer interrupt routine? Since the Tx buffer is full when this is enabled, I can expect the DMA to start transmitting right away, so I was wondering if there is a HAL method to disable the HTIE before starting the DMA.

We started developing using one of the boards from the MATRIX-M24SR board, connected to our own hardware (via I2C), and got it up and running also with writing to the whole NDEF file, with no problem.Then we developed a dedicated board including the M24SR64-Y. But for some strange reason, we can only write to the NDEF file within 16 byte blocks. E.g. Writing from address 0 – 15 works fine. Writing from address 4 – 14 works fine. Writing from address 16 – 31 works fine. Writing from address 10 – 17 don’t work. Writing from address 0 – 31 don’t work. I have verified that there is no password on the NDEF, but still, it’s strange that I can write to the memory in small blocks, but no in larger blocks (> 16 byte).We have tried replacing the onboard M24SR64-Y with one of the chips from a MATRIX-M24SR board, and then we can write with no problems to the whole NDEF file, so this shows that there are no problems with our hardware.

Hello. I use spc5studio and SPC582. i want use printf() using the UART for command line test. i alread tested serial. how can i setting  "stdio.h" header at spc5studio . ​please let me know code or seting.
