Background: If I used the Boot0 button, reset, and the demo-flasher, everything works as it should. Problem:My application needs to jump to system memory. I've read many post on this which should be fairly straight forward but after jumping to Sys...
Hi,I've been using an STM32L151 for a number of years...long enough ago that the firmware I wrote uses the SPL, not HAL, and I'm really not interested in re-writing the firmware!My problem is that a new I2c device I am connecting requires a RESTART b...
Hi,recently I changed my microcontroller from STM32L152 to STM32L552. In L1 I was using the code in the following link to activate the internal bootloader.https://community.st.com/s/question/0D50X00009XkeeWSAR/stm32l476rg-jump-to-bootloader-from-soft...
Hello, Please add an empty function on HAL for other MCU's what doesn't have that functions.For example HAL_ICHACHE_Enable() for F1 series. This feature can help to easy porting to other series of MCUs.Thanks.
Hello,Because there are negative side effects of using FatFS in my program to write logs to an SD Card, I am trying LittleFS library with an implementation of the HAL library.When I mount the filesystem &lfs I get a result of -84 which indicates that...
Currently, I am using the STM32L162VE custom board. I want to enter the USB DFU mode but am not able to enter the mode. This chip supports the USB and USART pre-programmed bootloaders. I have referred to the application notes AN2606 and AN3156. I did...

I am using STM32L151C6U6A device, both UART ports are used as RS485 ports. I am trying to boot from system memory and talk to bootloader using a USB-RS485 converter from my PC. Access to Boot0 pin is not possible in my hardware. So I am jumping from ...
I use ADC with DMA in cirular scan mode to convert two audio-channels triggered by a timer. This all works well with expected results and quality most of the time.For power-saving reasons I have to change the clock tree in runtime. This may screw up ...
After I successfully attached the board to my laptop and ran the "Press a button to ...." tests my plan was to proceed to the source code of the demo application:To read through the source code to familiarize with it.To compile it on my laptopTo flas...
