Posted on May 09, 2018 at 12:28Hello, I would like to save some data in the internal flash memory of an STM32L476. I found examples and guides and I was able to write and read data from flash. But I have a question: is the internal flash memory t...
Posted on August 11, 2014 at 12:00 Hi, I'm having a peculiar issue when jumping from my application code back to my bootloader. Before jumping back to the bootloader I disable all peripheral as shown in the code below. But when the HAL_NVIC_...
Posted on May 09, 2018 at 18:27I have written a firmware updater for the STM32F417, using the USART bootloader as described in AN3155. The updater/installer app is written in C# as a Windows app. It works on my dev computer (Windows 10), but additio...
Posted on May 08, 2018 at 19:44Is there somewhere a better description about this feature, than there is in the f070 reference manual? Maybe an example?I don't quite seem to understand how it's supposed to work. Or does CubeMX handle it somehow inco...
Posted on May 09, 2018 at 18:12Can someone show me a simple program to read and write the option bytes on the STM32L476VGT using the STM32 HAL libraries? I only want to change USER parameters values, as the BOR level.I'm trying the following code, b...
Posted on May 09, 2018 at 16:06Hi,this question may be hardware related. I saw some weird power ripple when I programming the STM32L4 device with JTAG. so can anyone explain what are GPIO status during JTAG programming? will it draw high current or ...
Posted on May 07, 2018 at 21:40Hi all,is there a way to improve LSE drift on L4 Nucleo board? Or all I can do is to migrate to another crystal with higher precision?Thanks, and regardsjerry
Posted on April 17, 2018 at 15:34HelloI am starting a new project in which I have to use a RS4785 communication and this time, I'd like to do it well.The problem is the following:If I want to receive a frame with UART using DMA, I need to call HAL_...
Posted on February 10, 2017 at 10:40I am getting Data Block CRC failure (DCRCFAIL) when I configure data transfer in SDIO using DMA.I am not using HW Flow control in SDIOThe same code works fine without DMAWhat is the reason for CRC failure and any ...
