Dec 14, Dec 17, Remove redefining include due to compilation error. Jul 13, You can get the official flashing utility from ST website here. The first one is a commad-line utility, second has a GUI interface.

There are parameters that you need to adjust to match your environment. For example "--pn" is the number under which the usb-to-serial virtual COM port appears in your computer. The "--a" parameter is base address in hex where to flash the "application. This is typically 0x to get the file into the beginning of the code space, so it starts executing on reset, however if you are uploading other data e.

Usage is:. These operations can be combined, for example the next command will first erase memory and then flash the binary. Not entire memory is erased that would be "-e --all" option as in global erase exampleit is sufficient to erase only the sectors your binary code spans across in our case the first, or "0-th" sector as they are numbered from zero.

For example, if your binary is larger than 32kB but smaller than 48kB, you need to erase first 3 sectors. For uploading a binary file manually, the GUI version is good.

It should auto-detect the COM port. Click "next" again. This is important as one sector is the minimal space which can, and must, be erased at once while programming can be done gradually, it is only possible to flip bits from 1 to 0, erased space reads as 0xFF.

With blank MCUs it is not necessary to erase anything at all. When re-flashing the binary, it is sufficient to only erase necessary pages - the utility will determine which sectors need to be erased automatically, based on binary file size. If everything went well, you should see this result, otherwise retry some of the previous steps - together or separately. In such case, next time try to flash the binary with "No Erase" option selected.

A few useful CLI commands There are parameters that you need to adjust to match your environment. Usage is: objcopy. After clicking "next", you should see this: Click "next" again.

Click "next" again, the indicator informs you about the progress. Follow us and subscribe to our channel! Powered by Drupal.Starting Electronics Needs Your Help!

Set up udev rules so that it is possible to run st-flash without using the sudo command. Change back to the stlink. In the terminal window enter:. In a terminal window, change to the directory containing the binary file that you want to load to the STM32 value line discovery board.

Where myflash is the name of your binary file to load. If you get an error message, then try using sudo in front of the above command or try rebooting the system. Twitter Blog YouTube Donate.This page is for instructions on how to flash firmware onto v3. For instructions on how to flash v1. If your v3. In the combo boxes [Board] and [Firmware Version] select the correct board and desired firmware version. If required or desired check the [Perform full chip erase] check button.

Finally, hit the [Flash Firmware] button. Now a black window DOS console should open and run the flash loader program, as shown in the screenshot.

Wait until it's finished takes some seconds. The STorM32 board will be reset and start running. In general, the STM32 micro-controllers which are used in the STorM32 boards provide two different built-in methods for flashing firmware:. For v3. Method 2. These are cheaply available, but nevertheless it is an additional piece of hardware, which one needs.

Now a black window DOS console should open and run the flash loader program, as shown in the above. Wait until it is finished takes some seconds. To buy one just search for e. They look something like this:. You need to install the right driver.

The SWD pins on the v3. It should look something like this:. Push the [Flash Firmware] button. For the v3.

How to Build, Flash and Debug the STM32 nanoBooter and nanoCLR on Windows using Visual Studio Code

Views Read View source View history. This page was last edited on 26 Novemberat This document describes how to build the required images for nanoFramework for STM32 targets. The build is based on CMake tool to ease the development in all major platforms. To simplify, this guide we will put all our tools and source in easily accessible folders and not at the default install paths you do not have to do the same :.

See next section for more info. See the Contributing to nanoFramework guide for specific instructions when contributing. Set up the CMake-variants. There is a template file called cmake-variants.

More info available on the Tweaking cmake-variants. For any of the Reference target boards you can find pre-populated template files here. Here is an example CMake-variants. Reopen VS Code. It should load the workspace automatically. In the status bar at the bottom left, click on the No Kit Selected and select [Unspecified].

Wait for it to finish Configuring the project progress bar shown in right bottom corner. Open nanoBooter. Make sure you tick the Reset after programming check box and hit Start. After the upload completes, the MCU is reset and the nanoBooter image runs. You can check the success of the operation watching for a slow blink pattern on the LED.

Congratulations, you now have a board running nanoFramework's booter!

I have to save certain parameters to the flash memory and these values should be non-volatile.

But my program will change these parameters and I want the changes updated to the flash. I understand to overwrite a flash page, you have to erase it first. And the granularity of erase operation is a page. Considering all of this, how can I properly implement it in software?

Whenever a parameter changes, should I erase the entire page? The page size is 1 kB, which is much space than all of my parameters put together. With most external flash memories, you can actually write to a page multiple times without erasing as long as you are writing to previously-unused byte locations. Please see this answer. However, the internal flash memory controller in the STM32's won't allow any writes unless the entire page is cleared.

If you want to go the easy route, ST has a freely-available software solution which provides an EEPROM emulation layer using an area of internal flash memory. It provides a simple set of functions, and handles all the complexities "under the hood". It allows for single-byte read and write granularity, and handles the erasing for you. I don't know which microcontroller you are using.

The software maps this location to a flash page, reads that page, inserts your byte where appropriate, then programs an entire new page onto another flash page. It bounces back and forth between pages, and keeps all this hidden from you. However, this is pretty time-intensive. Not only does it take a while, but your memory bus can stall while waiting for a flash write to complete, so you can't do this on timing-critical applications. If this software doesn't work for your application, you can build up as complex a solution as you need.

Once I wrote a large system for handling mission-critical configuration data, which data could change on the fly. It used multiple sectors, redundant locations, crc-verification, wear-leveling, etc. I couldn't rely on a table-of-contents, because what if the system powered down in the middle of the TOC update?Cookie Notice.

ST-Link Utility can program. The process described in this article outlines how to use the ST-Link Utility to program the internal and external flash of the ST boards.

For the internal flash, ST-Link will automatically detect the type of device connected. For an external flash, however, an external flash loader must be configured manually. When you flash a binary file using ST-Link Utility, you must supply the correct flash address manually.

This address must match the address used in the linker script. The default is the first address in the flash. When flashing a. ST-Link will automatically detect the memory ranges to program and select a suitable flashloaders to use, if so configured, when opening a.

As mentioned previously, the internal flash is always recognized by ST-Link for STM32 MCUs, but the flash loader for ranges starting at 0x must be configured manually. The makefile knows which external flash refer to table above to use for each of the supported ST boards. In this event, you may try to disable the USB device driver for that particular board in Windows Device Manager to fix the issue.
