Is it possible to Boot from system memory even if BOOT0 is connected to GND?
I have a question about internal bootloader in STM32L073 family. I have already made PCB with BOOT0 connected to GND (to boot from user flash). I would like to use RDP level 1. I jump to internal bootloader from my application (after receiving specia...
HAL_I2C_MasterTxCpltCallback does not report transfer size/count
Hello,I'm new to the forum. I have a Nucleo-L476RG board and I use Keil with Keil::STM32L4xx_DFP 2.1.0 to program it.During the debug I notice that after the HAL_I2C_Master_Transmit_IT(I2C_HandleTypeDef *hi2c, ...) function call the hi2c->XferSize an...
Can we deal with odd memory addresses and odd data length in case of STM32 custom bootloader?
We are writing a custom bootloader on STM32F102 and weknow we can write the flash memory in 16 bit wide steps.We use now a continous binary flash image, so if it's lengthwould be odd we can concate one byte easily. In near future we would like to use...
Resolved! ['F446 documentation] RCC - frequency limit of dedicated SPDIF-Rx output from PLLI2S
Posted on January 16, 2018 at 21:11However, SPDIF-Rx needs at least 135.2 MHz to support 192kHz audio sampling rate.Can ST please comment?Thanks,Jan Waclawek
Hi everyone, Has the factory bootloader any reason to do a soft reset before any command is received ?
I'm trying to use the factory bootloader from STM32l486 microcontroller without success. From the application code, the MCU jumps to the bootloader code located at beginning of the system memory using the following piece of code adapted from what I'v...
STM32H7 8xPDM microphones via SAI using STM32CubeMX
Hi guys,I'm looking at a number of ways to interface 8xPDM microphones and one of the ways is using an STM32H7 with it's SAI/PDM interface. According to the documentation (AN5027, 4.3.1), I should be able to select up to 8 microphones in the H7 SAI1_...

I have a working 3D printer, and an identical non-working one with a blown STM32F070CBT6. Can I extract the firmware from the working one?
I bought a second non-working used 3D printer with the expectation of repairing it. Turns out the MCU was destroyed - it actually had holes blown in its casing! I bought a few new MCUs of the exact same type, and replaced it. I can successfully put t...
STM32L433 USB transmit & received at the same time HAL lib bug.
There bug in STM HAL Lib generated by cube mx. Problem: I am using usb communication on STM32L433. I have high speed traffic both direction on the same endpoint. USB is stopped in one of the direction, and doesn't transmit/receive data any more.Why:I...
