stm32f4 discovery board?

Greetings eLua developers.
I just received an STM32F4 Discovery board, http://www.st.com/internet/evalboard/product/252419.jsp, and while trolling the internets for open source, linux based development tools I came upon eLua. It seems that with 1Mbyte of flash and 192kbytes of RAM and priced at US$19.50 this ARM Cortex-M4 board might be a reasonable candidate target board for eLua, but I'm working from a very sketchy understanding of eLua. Is it a reasonable target for eLua?
Many thanks, -- rec -- _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

I think so. So far I got the demo to compile on Linux using codesourcery. Need to load and go from there...

Sounds interesting. Also great price.

To answer your question, it is an _excellent_ eLua target. 192k of internal RAM in a MCU is a dream come true for me. I will end this e-mail now because I have to order one. Thanks again.

You're most welcome, and I will do my best to collect that debt from Bogdan!
The next question is how hard? I'm getting the impression that the basics won't be hard at all. Because the M4 is basically an M3 with a few extra instructions, all the essential MCU housekeeping is carried over from the M3. And because the board has hardly anything on it but header pins, the initial pin configuration could set nearly everything to gpio. And anything that's already working for other STM32 boards (USART, CAN, I2C, SPI, ADC, DAC) probably works on this board once the pins are mapped and configured correctly.

I have the same impression. The core is not that different and I don't see why they would change their peripheral silicon implementation (although I didn't check this yet). I didn't order a board yet, I'm still trying to find a suitable distributor in Europe. It's quite new though and this isn't easy.

Hi,
Mouser and NU Horizons have them for US$ 14.88 (!!!!!!!!!!!) http://br.mouser.com/ProductDetail/STMicroelectronics/STM32F4DISCOVERY/?qs=sGAEpiMZZMutVogd4PRSvEN8XDBeCtgD http://www.nuhorizons.com/development/devtool.asp?board=264 Tks Mauricio !!!!!!!!!!!

I just got my board on tuesday. I went to one of the free seminars. Just FYI, during bringup of the silicon they used the STM32F2xx libraries to test and work with the device, so yes the peripherals are the same. The only issue you may encounter is there are some differences between the F4 and the F1 series peripherals. Oh and 64K of the RAM is only accessible by the core as data memory, just FYI.
Over all it is a nice board and the target price is in the $14 range (as was stated at the seminar).

Too bad it's no longer in stock ìn Mouser, and the shipping is usually expensive. Maybe we can do a batch order to Brazil?

Thank you. Interesting choice. They're probably trying to maximize parallelism or something like that. Oh well, from what it looks like this 64k memory won't be able to execute code, host a DMA buffer and other stuff that I'm probably missing right now, but it's still good for our precious Lua data :) > > Over all it is a nice board and the target price is in the $14 range (as was > stated at the seminar). Yes, I'm absolutely blown away by the price/performance ratio of this board. _Really_ giving 8-bit MCUs a run for their money.

The main issue I'm having is getting tools for Linux and open source needs to be open source. For example, the built-in JTAG is SWD and is only supported by vendors, it uses some MASS storage protocol. So, need to find SWD or different firmware for the JTAG. So, I'm trying to use the built in USB DFU in the boot ROM. The DFU file must be formatted, so looking at that. I have the ST example code built and linked, but trying to download it is my current problem.

It hasn't been listed in stock anywhere, yet, mine is a free sample shipped early.

Personally, I gave up trying to import things legally to this country a long time ago. My orders _never_ arrive or are insanely overtaxed. But this is just me. Mauricio and Vagner have imported some kits lately and it aparently worked fine. I was away on vacations, which seems to be the reason why :) Best Dado

I am confused about that, too.
So the board has an stlink processor on the mini-usb connector which twiddles the SWD. This project http://code.google.com/p/arm-utilities/ claims to be a download/upload/debug interface to stlink from linux. Apparently, stlink is only nominally a mass storage device, it's implementation is broken in multiple ways that only Windows forgives.
But I'm puzzled by the contents arm-utilities/stlink-download. Guess I should just compile something and try flashing. -- rec --

Great find, I found python script(http://www.seeedstudio.com/forum/viewtopic.php?p=4504#p4504) to format the image, but looking for a Linux DFU to upload for this board. There is AVR etc, hope that works. If you want please let me know if it works. I'm going keep doing on the DFU side of things. I found the Windows software at http://www.st.com/stonline/stappl/resourceSelector/app?page=resourceSelectorPage&doctype=st_software_rsrc&FamilyID=141 So, with the python script and the bin, I ca see if my app loads... then can start on a port to eLua.

Yes, UM0391 (DfuSe File Format Specification) is available after installing the DfuSe software (Windows only) from here: http://www.st.com/internet/com/SOFTWARE_RESOURCES/SW_COMPONENT/SW_DEMO/um0412.zip I'm not attaching it to this mail as I have no idea what licenses I might break by doing so.

Well, I do have an old datasheet called: AN3156 USB DFU protocol used in the STM32™ bootloader, however it doesn't detail binary files, only DFU commands per se.
I could write something in C++, but unfortunately I have no way to test stuff, since the only DFU chip I have is an ATmega32u2. My STM32 does not have a DFU bootloader (only the connectivity line has it). Maybe I can try it with the maple DFU bootloader. By the way, if the maple is programmed with DFU, and they have an Arduino-based IDE, maybe they already have those converters. More info: http://leaflabs.com/docs/bootloader.html Ronan 2011/10/13 Bogdan Marinescu <[hidden email]>
