Hello, really good & informative tutorial. I have successfully done this. But there is a problem now stlink is not communicating with stm32 board it gives internal command error. what should I do ? how I can retain original configuration of stm32 baord ?

Use Mini USB connector (not the Micro). Also erase the chip and sectors completely and you are good to go.
To get the firmware that board already had when you received, you need to download it form the ST site. I forgot the location, but it was along with their peripheral library. Download it and compile it with Keil or other compilers (you get free versions with code limit – don’t worry, you won’t exceed).

Update on USB driver problems – solved!
I posted on 31st Jan about problems I was having getting the USB link to work reliably. There seemed to be a caveat about the USB drivers (‘for evaluation only’) and I had assumed that was the problem and laid all the blame on that. I corresponded briefly with Cuno Pfister and he explained that there was no problem with the drivers, only that a licensing issue required them to be released as ‘for evaluation only’. After LOTS of installing and re-installing I finally found the cause of the problem – my ‘5V USB supply’ was actually running at about 4.5V, and this caused the intermittent and sporadic failure of the system. Since I started using an independent 5V supply ALL the problems have gone away – if you are having problems, check your USB supply voltage.
I’m still looking for a definitive list of pin numbers/device numbers for all the interfaces. I have got the 4 LEDs going (at 100kHz), plus UART and PWM. I’d like to explore I2C but don’t know where to start looking – even when I find the pin numbers, its not always straightforward to link up with the .NET/c# references to these I/O systems. Is there a definitive list anywhere? Anyone fancy drawing one up, or starting to contribute to the development of one?
This is a fantastic piece of kit which exploits the rich development environment of .NET/c#/VS2010, although I have yet to push the boundaries of performance, given the limitations of .NET.

Hello, thanks for the article.
I have done program the boot loader, MS deploy detects my STM32 Discov, All is ok. But when i compile (USB in property setting as you given) nothing happen, when i press debug button it will be disabled, hope the debugging is going on, but even after 2,3 minutes it is the same. Can we see program loading?
What will happen when we press debug button?

Hi,
I appreciate your article a lot. However, I have serious problem forcing my stm32f4discovery board to work. I successfully uploaded tinybooter.hex and after reset, the system (win 7 x64) detected STM32 .Net Test device. I chose usb drivers to install then and everything appeared to be fine. But MFDeploy cannot see any device connected to USB. I have rev Z board. There is nothing connected to the board except two usb cables and I ereased my chip using ST-LINK utility. Any ideas? I really wanted to evaluate .Net framework on my ARM uC. Thanks in advance.

Hi L0nger (and everyone)
I’m having the same problem with the WinUSB drivers. I have had the whole thing up and running, and I’ve deployed several apps to the STM board, but then it all stops and Windows either doesn’t recognise STM.Test or it recognises it and then says there is an error. Endless connecting and disconnecting and erasing and reflashing sometimes fixes it, but often doesn’t. Under these conditions MFDepoy cannot see it.
Its a great pity, because when it does work, its fantastic! I’ve posted a query to Cuno Pfister who seems to be the originator of some of this – especially the drivers – and am hoping for some advice. The WinUSB drivers do carry a warning though, so we may have to accept this until they become more stable. Trouble is, I really want to get going.
On a slightly different topic, when it did work, I managed to get all the GPIO pins toggling – even the four LEDs on the STM board, but I’m stuck as to how to find the PWM, I2C, UARTs etc. (and which is which). I’m sure its in the documentation somewhere, but I’m not all that familiar with this stuff, so I do not know where to look.
Anyone help?

Hi,
thanks for your reply. I will greatly appreciate if you post some information about the driver when you contact the author.
It seems though that it’s the matter of driver, not the board. I really doubt that boards rev A,B,Z differ much from each other.

After downloading the tinybooter.hex and restarting the board the mini usb is used as a mere power supply. The micro usb connected is what the microframework will be dealing with.

Yep, you’re right. I tried connecting and disconnecting, erasing and flashing many times. Nothing helped. The driver installs well, but MFDeploy cannot see the device.

Sorry to be a bit picky – I like this and I’m going to try it – but the first picture shows a USB Mini connection, not a USB micro connection – which is correct?

The mini usb will be used up till you burn the tinybooter.hex. After that the mini usb will act just as a power supply for the board. The micro usb will used for the other 2 hex file and MFDeploy step.

Hi there! Nice write-up. I’ve been trying (with little success) to follow your procedure.
I’ve hit a stumbling block when deploying the ER_FLASH hex file, using MFDeploy. I am able to do everything up to this point, including load the ER_CONFIG file successfully, but I can’t get ER_FLASH to deploy. The process starts, and then fails when attempting to write (may have been erase, I’m not at work to check currently) the first memory location for the ER_FLASH file.
Can you offer any thoughts as to why this may be? I have the GHI gadgeteer system installed, but that shouldn’t be affecting this separate process, right? Maybe I somehow have a different version of the ER_FLASH hex file?
I’d be very grateful for any suggestions from anyone!
Cheers,
Tom

Are you working with STM32F4 Discovery board? Make sure you have nothing connected to the discovery board (all pins should be free – nothing should be connected to the pins.also make sure when you erase the chip you also did erase all the sectors (as given in the screenshot. Try writing ER_FLASH first. Also make sure you downloaded the right files. The gadgeteer will not affect this.

The board is stock, fresh from the blister pack. Nothing is connected to any pins. I have followed your procedure to the letter, and tried several times, including varying the order of ER_FLASH & ER_CONFIG, with the same error every time. The files were downloaded from the link you provided… I will try with a colleagues board tomorrow, but given that the error exists for only ER_CONFIG, I suspect that file, rather than hardware. I will re-download the files and try that too.

Hi Again,
I’m still having trouble with this! I’ve checked all the previously mentioned points, and the only difference that I can find in my method / setup is that I have a Rev Z MCU, as opposed to your Rev B. Is this likely to make any difference?

Hello!
I’ve finally found where my process was falling down. In MFDeploy, I was selecting and deploying the ER_FLASH and ER_CONFIG one by one. This always resulted in failiure.
If both files are selected in the browse dialog, and deployed together, the procedure works.
With that sorted, I’m now up and running with the serial ports and LED’s, with my sights set on the rest of it before too long!
Thanks again for the writeup,
Tom

Simply try this :

And connect to the related pins on the STM32F4DISCOVERY :
rxPin = Pins.GPIO_PIN_A_3;
txPin = Pins.GPIO_PIN_A_2;
ctsPin = Pins.GPIO_PIN_A_0;
rtsPin = Pins.GPIO_PIN_A_1;

If you use this code you dont need an external LED. You have to add c:\MicroFrameworkPK_v4_2\DeviceCode\Targets\Native\STM32\ManagedCode\Hardware\CPU.cs to project.

using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;

OutputPort led = new OutputPort(Microsoft.SPOT.Hardware.STM32.Pins.GPIO_PIN_D_12, false); //PA1 on discovery board
while (true)

I doubt it. CLR requires at least 64KBytes of RAM. F3 series according to ST’s site says “The STM32 F3 series includes devices with 64 to 256 Kbytes of on-chip Flash memory, up to 48 Kbytes of SRAM” which i don’t think is sufficient.
