How to flash firmware

Flash firmware using a usb-ttl adapter

1. one needs a standard usb-ttl adapter (FTDI, CP2102,...), ensure that it's working (drivers installed etc.)

2. one doesn't have to worry if it's a 5V adapter or not, the pins we're going to connect it to are 5V tolerant

3. the adapter has to be connected to UART1, which is NOT the port labelled UART on the board, the correct pins are found on the port labelled RC! Namely:

RC-GND = GND -> connect it to GND on the usb-ttl adapter

RC-0 = Uart1-Rx -> connect it to Tx on the usb-ttl adapter

RC-1 = Uart1-Tx -> connect it to Rx on the usb-ttl adapter

Comment: neither a 5V nor a 3.3V, nor whatever power pins are there on the usb-ttl adapter, are used... only three wires running from adapter to board

4. the board should be powerd via the USB plug or through a battery/power supply connected to the BAT pins (only experts who know what they're doing should use any of the 3.3V pins on the board)

5. run the GUI and go to the "Flash Firmware" tab

6. select the correct board and desired firmware version from the selectors, or browse to a specific hex file

7. select "System Bootloader @ UART1" in the STM32 programmer field

8. select the COM port which your usb-ttl adapter is connected to

Comment: if you're not sure which one is the correct COM port, then disconnect the adapter, inspect the drop-down list and memorize the available COM ports, connect your adapter and wait until its enumerated by Win7, finally inspect the drop-down list and chose the newely added COM port

9. if required or desired check the "Perform full chip erase" check button

10. this is now important: before hitting the "Flash Firmware" button one has to get the board prepared to be ready for being flashed. For that, with the board connected to power, one has to

• press and hold down both the Reset and Boot0 buttons (the exact sequence of when which button is pressed is irrelevant, as long as they're hold down)
• then, release the Reset button while still holding down the Boot0 button
• then, release the Boot0 button

Comment: this may sound complicated, but one will quickly realise that this can be done by "rolling" the finger tipp from the left to right

11. finally, hit the "Flash Firmware" button

Now a black window (DOS console) should open and run the flash loader program. Wait until it's finished (takes a couple of seconds).

Comment: if the verify fails then check the "Perform full chip erase" check button and repeat, this will however also erase any setting which you might have stored before, in that case save the settings beforehand using the option in the "Setting" menu .

Error: mfc110.dll is missing msvcr110.dll is missing Application Was Unable To Start Correctly (0xc000007b)

Solution: ich habe das cpp mit Visual Studio compiliert

ich habe nun ide Info gefunden "If you want the program to run on another computer as well, that computer must have VC++ Runtime libraries installed. C++ programs built using Visual Studio require them. You won't need it on your machine because it gets installed with Visual Studio. But you can't expect your clients to have it.

-> hin gehen: http://www.microsoft.com/en-us/downl....aspx?id=30679 und das installieren auf dem win x64 wo das vorher genau deine Fehler gemacht hatte, habe ich einfach vcredist_x86.exe gestartet, danach startete "mein" Flashloader
