Runtime DFU application in STM32L4 series

Hello Everyone,

I need DFU application which can load the new firmware at run time.

I want to implement DFU in stm32l476G-Eval board, tried with DFU bootloader method (Connecting Boot0 to VCC) it is working fine.

Compiled the DFU standalone example application and ran it but it is not showing as a DFU device when i connected the eval board to PC.

Can any body explain or point me to the links which can explain how to implement the DFU standalone method. How the run time DFU will work? how much space it will take for the DFU code?

#stm32l4 #usb #stm32l476g-eval #stm32l4-dfu-runtime #dfu

Can any body give suggestions on this?

How to get the DFU run time with DFU class enabled.

Hi ,

I'm also trying to implement Run Time DFU via USB in STM32F207ZG port but I can't able to get proper document for that,

Any suggestion ? Pls share your Ideas...

With Thanks & Regards

This is the mechanism I use on F2/F4 designs to boot into the System Loader's DFU mode

Hi

K.Manikandan

‌,

Have you achieved runtime DFU on STM32F207ZG nucleo?

Hi ,

I just tested with /home/STM32CubeF2/STM32Cube_FW_F2_V1.4.0/Projects/STM32F207ZG-Nucleo/Applications/USB_Device/DFU_Standalone ,by using this code I can able to detect the DFU device and also possible to upload the .dfu file.

Hi,

=====================================================================================

When I'm using BOOT0 pin = 1 and BOOT1 pin = 0 then I got below output (For Making Boot0 pin as 1 , I put Jumper between BT0 and VDD ( CN 11 - pin 5 and 7)

For Making Boot1 pin as 0, I put Jumper between PB2(BOOT1) and GND (CN12- pin 20 and 22)

Hi,

Check out my self-made bootloader. It does not require to utilize the BOOT pins, it features firmware update from an SD card, and also provides possibility to jump and launch the built-in st-bootloader (tested and works in DFU mode).
