hi everyone... mi name is hector and i am a curious of embbeded world.

I discovered this kit on the interner and logicaly, i have one.

the very important reason that i am writing something here is:

1.- I plugged the board to usb and demo application works very well. ( 1.- o.k.)

2.- i choosed Atollic True studio( 2.2.0 lite version ) to start with demos, examples and so on(2.- o.k)

3.- After this, i really disappointed, of course not for board or softwre. The main reason is that i can not compile none of those programs with atollic. i did all of things that say in manual and nothing happend. just appears bad and bad and bad on console...(3.- fail)

4.- ok, maybe is a bad setting or one o two files that i forgot( i dont know yet) ... but i tried to use STM32 ST-LINK_V2.1. I assume, this utility, have to works with board.. right?? but nothing is happening...(4.- fail again)

5.-and ideas came to my head.. if st-link is a programmer-debugger, when i connect through usb, Usb on board could flashing??? (is it possible??).. and why Win7(sorry) says ''this strange something wear bla bla bla.. is a unknowing dispositive'' despite on computer resides Stlink usb driver.dll, instalation of usb driver was made, and so on..(5.- confused).

if anyone could help me, please let me know where i failed to get the truth about stm board.

all feedbacks are important for me...

thanks a lot evereyone

I found Atollic Lite to be un-necessarily difficult to build pre-existing projects with. The ones provided by ST were built with the full version, and make some assumptions about workspaces and such. Generally it wasn't a compile-and-run experience.

Try using the eval versions of Keil, or IAR. There are some issues with the download mode of the ST-LINK in Keil, but the debug-and-run option does work.

ok. let me prove..

so i want believe, if i dont have install any enviroment, the STM32VL doesn´t work?

i mean ,''doesn´t'' properly??

Thanks a lot for your time

Well I'm not sure you need development tools or an IDE. You can program the VL Discovery with the ST-LINK utilities, and the board looks like a Mass-Storage device so you an pretty much plug it into any PC to provide power to the board, and it will run the code you have burned into flash.

It's a cheap board and adequate for playing around, or doing a quick prototype or design mash-up. Things are better with the more expensive boards and tools as they are more refined. For instance the U-Link and J-Link JTAG pods are far more robust than the ST-LINK, and the Segger J-Links are usable with pretty much all commercial development tools.

Of course, it is not a ''specialized'' development tool, it is just an evaluating board to introduce yourself to the world of STm32. i think so.

But, my main problem is that board does not work with St link utility. i pluged, it starts blinking, but st-link utility does not recognize. is like stlink, on board does not have Bootloader or firmware that manage the usb protocol, is it possible. let me put a picture. sorry about but my native language is spanish, and how you see, my operating system too.

And it is that i cant undestand??

Hello, maybe reinstal the st-link driver, you can fine in the ST weeb page.

actually, i did it.

you know what???

i change my usb cable, and guess what?? windows recognize stm32vl as massive storage.

olso,  i could compile the demo on atollic.... but,,,, unfortunately i can not program or debug it..

really, it is so wear... i hope someone knows the answer??

Examples of STM32VLDiscovery boards are written using old versions of the tools. So they don't compile. You need to do required corrective actions to make these examples work. For KEIL, I need to copy system_stm32f10x.c to project files and remove core_cm3.c files. Then all the examples work fine.

it could possible.

i can fix it up,,, maybe.

but i still having the common problem that none of ide detect board, stlink utility does the same thing.. whats happening?

In previous post, you claim that it was detected by changing USB cable. Can you please explain the errors you are getting

When you plug the board to the PC, it may appear like a disk.

Try follow some of these:
