I saw a strange behavior when using STM32F401RBTx, to show you I added only 1 output as LED and toggled it. I have just that much code. I tried with 16 MHz, 48 MHz, 64 MHz, 84 MHz. It went hard fault when speed is 64 MHz or 84 MHz. This is th...

Hello,in Application Note AN6228 it is stated, that it is possible to perform write-operations on the external flash while running code in memory-mapped mode (Execute-In-Place XIP) on the same external flash memory (on a different bank).See:https://w...
Hi all! AGENDA: Need to verify the external QSPI flash (AT25Q128A) all sectors Write, Read and Comparing with STM32L496ZG-P using driver code. APPROACH: For write, I am have created a buffer which comprises of page size of 256, and I am using two "fo...
Hi, Please help me sort this out.I am trying to port a custom bootloader originally written for the SAMD21 Arm chip to the STM32U385VGT6. We are upgrading our current product with an STM32 Chip. I am having problems with switching from the bootloader...
i am trying to read the jedec id from the MT25TL512HBA8E12-0AAT TR using stm32h750xbh6 with qspii configured qspi using mx like follows:hqspi.Instance = QUADSPI;hqspi.Init.ClockPrescaler = 1;hqspi.Init.FifoThreshold = 4;hqspi.Init.SampleShifting = Q...
Hello, I am working on the STM32G431RB Nucleo board, specifically on the internal temperature sensor. I am facing issues in getting accurate readings. For your reference, I have attached: My code implementation An Excel sheet comparing temperature ...
Hello, We're working on a custom board for the STM32H750IBX. Our boards arrived. The first time, the chip was installed poorly and shorted out. We assembled a new board at the SMT factory with the new chip, but we still can't connect to the chip to p...
Hi all,I am experimenting with H7 ADC (after having tried the G4 ADC).I see in the HAL that the calibration, HAL_ADCEx_Calibration_Start(), for H7 MCU wants a parameter more than G4. One should specify ADC_CALIB_OFFSET or ADC_CALIB_OFFSET_LINEARITY.I...
I have implemented a design using the STM32N645X0H3Q (though I have placed the STM32N647X0H3Q) using external VDDCORE. R110 is not mounted (to set VLXSMPS to NC)On startup I have VDDIO (3.3V) and VDDA1V8ON (1.8V) to the MCU, and the MCU activated PWR...
