* Step: Disable systick timer and reset it to default values #endif /* defined(USE_STDPERIPH_DRIVER) */ * Step: Disable RCC, set it to default (after reset) settings * For other families, check AN2606 document table 110 with descriptions of memory addresses * For STM32F429, system memory is on 0x1FFF 0000

* Call function when you want to jump to system memory * Function to perform jump to system memory boot from user application

Set main stack pointer to value stored at system memory location address.

Set jump location to memory location + 4 bytes offset.

Map system memory to 0x00000000 location.

Disable SysTick interrupt and reset it to default.

Set RCC to default values (the same as on startup) [Internal clock, no PLL, etc.).

Find system memory location for specific STM32 in AN2606.

If you wish to just from main program to system memory at anytime, some important steps needs to be performed first: Since now we know where our memory address is, we have to perform jump to that location and if possible, reflect system memory to 0x00000000 address so that MCU sees this at start address. Now, each device has this on different address, but on STM32F429, which I use, it is available on memory location 0x1FFF0000.Īpplication note (AN2606)describe bootloader in details and also gives you information on where is memory location for specific device. Since we know system memory is available, we also know that it is somewhere in memory on specific memory location. To make hardware development easier, we can set BOOT0 pin to GND and force device to always jump to main flash memory. When (normally) main flash memory is used, only BOOT0 configuration is required, BOOT1 pin does not care. I have gone into device manager and uninstalled everything in USB controllers, although they reinstall on start up but at least I get to reinstall the STM 32 DFU after I've done that.BOOT0 pin is dedicated on device, while BOOT1 is shared with PB2. On my laptop there are no other USB devices connected. I have tried it on six USB ports on two computers. The computer sees it as a USB device, but that's as much acknowledgement as there is.nothing in DfuSE, no change in the screen on the 7E (just shows 'Program Update.' and a little window half filled with vertical lines. Under My Computer STM 32 DFU never shows up as a device with removable storage, although that's perhaps because it's still with the original FW. Under 'Safely Remove Hardware and Eject Media' I can remove the STM 32 DFU, at which time it goes away in Device Manager. In Device Manager, under USB DEVICES, I have STM 32 DFU. Nothing appears in the DfuSe 'Available DFU Devices' dropdown list.

I click the 'details' bubble, and find 'Driver software installation STM 32 DFU Installed, STM 32 DFU Ready to Use'

When I turn on the 7E holding the EXT button, Windows 7 informs me that it is installing device driver software. I downloaded and installed DfuSe from the Walkera website, it opens nicely. I got a 7E for Christmas,and there has been no joy whatever.

Normaly at this point windows should install drivers at this point and after that your devo is shown in your dfuse program. I guess this is the point were things go wrong in your case. Hold ext button and power up transmitter. TomPeer wrote: i asume you have done all this, but doing a resume:
