Resolved! STM32H7 - Jump to Application from custom bootloader fails when compiling in release mode
Hello,I have developed a cusom bootloader for STM32H743; the bootloader gets an image file from serial port, writes it in FLASH at address 0x08020000 and then jump to it.The function I have implemented for jumping is the usual one:void runApplication...
STM32H743XI series set QUADSPI_CCR will rasing cannot access Memory.
I'm using STM32H743XI series and want to control external nor flash(MT25QL512A), and i have been initialized qspi by HAL_QSPI_Init API and return correctly. I found that when i config QUADSPI_CCR it will show cannot access Memory.I have confirm that...
Proper way to set up the PWM input using Tim2 ch1 & ch3?
I'm using the STM32L031K6 chip. I have a 100HZ signal connected to PA0 (Timer2 ch1) and PB0 (Timer2 ch 3). I think I've setup everything correctly using the CubeMX.The problem I'm finding is the interrupt only fires for the positive going edge on T...
Buffer size error when compiling the embedded webserver on STM32F7 with a different display image than provided. Any ideas?
I am running the embedded web server on the STM32F7 and I changed the linked image that is displayed on the MCU. It compiles, but doesn't display. After investigating, a buffer size error is being thrown and consequently the main code gets stuck in...
Access ETM only with code without the use of debug kits
My board is Nucleo F401RE. This is the first time I've ever been doing this.I am using a pointer to the main registry of ETM, its address I read it on the datasheet.My problem is that wanting to change the bits of this log I do not change it the corr...
[STM32L476 DISCO docu] incorrect solder bridges description
These solder bridges are in fact by default OFF, as these signals would collide with the LCD (as text elsewhere in the same manual points out).May I at this point ask again for a table with describing connection of all pins on the target STM32L476, a...
Vdda Vs Vdd Stm32l433cc
HiMy stm32l433cc circuit has two different LDO, one for Vdd and another for Vdda. Can you tell me please can i run my controller without Vdda power? I need to turn on/off analog power when i need it. Is it possible on stm32l433cc?
Resolved! Incorrect SPI clock frequency
Hello,I'm trying to get data from an external ADC (18bits) with an STM32l476RG nucleo board. There is a lot of overhead and I will improve it later but even the frequency clock is not fast enough. I don't understand why but the maximum clock frequenc...
Read data from ADC and send it via I2S
Hi guys! In my project Im reading samples with the adc at 48Khz using timer interrupts and adcConvCallbacks, load them in a buffer of 256 samples and when the buffer is full I send it via i2s to the DAC . Im using two buffers, when the bufferA is ful...
