5 minutes well spent! thank you.

Can i enable read-out protection using dfu mode after programming?

[@aaammm6447]

what is the jumper setting for stm32l152 discovery board to go into DFU mode

[@Mitt0]

How to program read-out protected device from bootloader over DFU?

[@KeyboardMac]

can it also copy or read the code from the STM32 chip?

[@nachocelano4861]

Hi, we are working on a STM32f407VGT6, we want to upload VESC bootloader. Do anybody know if it is possible? We succeed in uploading all the files but VESC tool does not recognize it....

[@maciejgrochowskii]

Is DFU working properly without external crystal? I remember that without crystal I had a lot of issues with embedded USB on microcontroller

[@sagark2686]

sir, i have only connect boot0 pin to vcc to enable dfu mode.there is no another process is required

[@osmanozdemir4367]

Can i do with blue pill (stm32f103c8t6)? please answer me quickly

[@chloep7605]

I have a STM32F429I-DISC1 and I want to activate the USB port CN6, it's why I watched this tutorial but it doesn't work. My computer doesn't detect this port. Despite, I connected the pin BOOT0 to VDD and BOOT1/PB2 to GND thanks to jumpers, then I reset but the DFU port wasn't detected by the computer and the screen of my STM32 became fully white. I have the feeling that the solution shown in this video doesn't work for this type of STM32. So I would like to know what I am supposed to do to make it work. If someone knows, thank you for giving me the answer.

[@askinc102]

I am facing the same issue right now. Please let me know how you resolved it in case you did

[@nfsrival1499]

how do i excess the dfu file manager?

[@Nachodis]

For what it's worth to save someones time: it seems that Dfu File Mgr and DfuSeDemo are deprecated on windows 10, it's recommended to use the stm32CubeProgrammer in USB mode.

[@phillipzx3754]

You just saved me. I've been fighting with the DFU file manager and DfuSeDemo trying to convert/use a binary file. It wouldn't even see the new DFU file created. No go under windows 10. Once I installed stm32CubeProgrammer I used the binary. I didn't even mess with converting it to a dfu file. I was trying to flash my NanoVNA with a firmware version that worked with Joe Smith's software.

[@danielliden6829]

I have an STM32F4 with both BOOT1 and BOOT0. I guess the BOOT0 is just as this video (tie to supply when programming). But how should the BOOT1 pin be pulled?

[@MKVideoful]

Checkout schematic in which state is BOOT1 and BOOT0 by default. Also checkout boot modes in datasheet, after reset the cpu should boot from system memory area, where the bootloader is placed.

[@jdmuys]

I need a Mac version of the software too

[@Aleynikov]

When STM soft will comparable with MacOS?

[@joaoteixeira8007]

I have STM32F407VET6. I can upload programs in DFU mode, however when connecting the board in USB Serial mode, STMCube shows this error: Timeout error occured while waiting for acknowledgement. Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again... How can i fix it?

[@davesmith679]

where can i download the bootloader

[@kaihorstmann2783]

The bootloader is pre-programmed in a ROM area on the chip. The MCU is shipped with it. It cannot be updated or re-programmed at all.

[@FrodorMov]

Well god damnit, just had boards manufactured with boot0 to ground. None of the documentation on the stm32f072 mentions the USB bootloader. Well, the STM32F072 Discovery User Manual (UM1690) does... I mean, really ?

[@ryansturmer]

You can jump into the bootloader from software as well - it doesn't help you with bootstrapping, but once you get your application down the first time, you can make it work...

[@osmanozdemir4367]

Can I upload code to the same processor over and over again this way?

[@stmicroelectronics]

Hi there, thanks for your question - may we point you towards our community.st.com, where you will find a team of people who can answer you directly ?

[@kaihorstmann2783]

Yes you can. It is Flash Memory. However Flash wears out when being re-programmed many times. So after a couple thousand re-flashes it will eventually fail.

[@The2Coolest2]

The circles you have to spin in to just get one thing working is criminal.

[@premanandpatro788]

how to do in python?

[@mikewaxx]

ok what you mean is "getting started with the 72 disco board" these directions won't work with any other hardware.

[@saeed6296]

really windows 98 !

[@ferchuu9]

it is windows 7 or vista
