Hello everyone,I'm using a STM32L4 in a application and the BlueNRG-LP as a BLE module in network coprocessor mode with DTM SPI. I'd like to update my main firmware through BLE OTA, a kind of Bootloader OTA. So in my main MCU, there will be this Boot...

Hello everyone,I'm working on a project with BLE technology,I have a ST-BlueNRG-LP device which is controlled by a host STM32 through HCI/ACI commands.I was wondering if it is possible to set my Host STM32 in a sleep mode while the ST-BlueNRG-LP is s...

Hello everyone,I'm working on a STM32L4 project which embeds a QSPI external Flash Memory (not yet sourced but doesn't matter).This QSPI Flash Memory would be splitted into 2 parts, one for TouchGFX Images and one for 10MB Filesystem. This FS will ha...

Hello everyone,I'm working on a new project using TouchGFX in STM32CubeIDE, I don't understand why I have include problems, especially that a file is recognized in one file and not in an other...Here is my includes : I've got these errors :What is we...

Yeah sure, I wasn't clear, I don't erase each minute, I shift a pointer and when the sector is complete and passed, I erase it, which means that I erase each sector once per month.

Hi Pavel,It's a sliding log, each minute I erase the oldest value and I write the new value. I had planned to make a custom wear leveling with raw dataLog into the Flash Memory without any FS.But the objective is to store the log in a file (.txt, .lo...

I want to keep 2 DataLog files, one of 300kBytes to retain a month of a sensor value, updated each minute (not second as I wrote, so more than 500 000 updates per year), the second one is 40KBytes for something else. So I'll have 2 log files and one ...

Yes it is, for example, I made a simple application with just image_d13 on my screen, here is how it is stored :And then, this is how the program recognizes my image in the memory at address 0x8006900.

Thanks for the detail ! My Write, Read and SectorErase functions are working great outside the loader. I just have to focus on my external loader now.Here is my two files : Maybe my error could be from my .ld file which is not from my microcontrolle...

Porting BLE_OTA_ServiceManager on a host processor and use the BlueNRG-LP as coprocessor

Possibility for the host MCU to go Sleep modes while ST-BlueNRG-LP slave device is scanning ?

STM32L4 : Using a part of QSPI external Flash Memory as a frequently updated data log, accessible by a PC with USB MSC (Faisability demand)

Where could I find the sources of each external loader ? I have a Serial NOR Flash Memory MT25QL512ABB which is already implemented with different MCU's but not mine, I wanted to get the sources of an other MCU and to porte it to my MCU STM32H7B3xx.
