Great way to limit yourself to your own toys.
I would recommend CrossWorks Studio + JLINK jtag/swd adapter.

like I said - preferably. I use whatever works best, but if I have a choice I follow my own preferences. YMMV.

thanks for the hint.

any info on that? yes, I have seen a list of possible candidates in an earlier post, but is someone actually doing a port?

It's hard to do anything without seeing the board (I got one on the way but it'll be a while), I've started cleaning up my STM8 MultiWii port so that it can also run on STM32, as well as started (nothing commited yet) making it run on OpenPilot hardware. I'm using it's usb as virtual com port, so that's where I'm currently stuck. I suspect if I ignore that part and just do it plain old uart style the 8->32 port shouldn't take long at all. You can probably take the lazy way out and use something like libmaple but there's a lot of hardware-specific stuff in multiwii that doesn't use arduino framework (rx, serial, pwm?) etc so... It might not be a good idea.

Paparazzi?

Well, paparazzi project at this moment uses STM32, but their hardware cost a lot (more than i can pay - Lisa/M is 250$ with Aspirin IMU, shipped from USA, with tax and shiping it's 380$ here). Of course, sensors (gyro/acc) won't be supported out-of-the-box, but other hardware (at least, init, to do some further debugging) may be possible?
What do You think about? I got no expierence with microcontrollers, but know linux (no kernel hacking/hw, but no problems modifying existing code) and a bit of C. If You think that may be possible to use this board to run paparazzi (with added baro probably) - i go order one...

This thing only has 64k flash device (STM32F103C8T6), I think something light weight like multiwii is the easiest to get working on it. Paparazzi probably needs a lot more than just sensors on board (but I never looked at their hardware so I dont know).

Well, Lisa/M schematics says:
  • Minimum: STM32F103RB
  • Maximum: STM32F103RE
And there's Lisa/S (draft so far, no working devices).
So, IMO only 64K vs 128K minimum flash size (freq, Internal RAM, timers, etc - the same) difference.
And because STM32 on this board is surface-mounted, shouldn't be so hard to re-solder (like ppl did with KK board chips)?

Would be nice to test one, but with quad-only configuration and no alternate configurations - probably will be useless for me (i have hex/tri)

EDIT: checked datasheets again, due to different form-factor wouldn't be easy to swap chips.

I know about your stm8 port.

from what you know, is porting openpilot to this Ff board a probable task?

If you rip out USB stuff and manage to make it fit into 64k etc, it might just work.
maybe something like movecopter branch of OP would be an easy target to fit to this board since I believe it uses a bunch of i2c sensors. (hm, just checked - or not - only mag is i2c).

Ordered one anyway. Will try to put some code from other autopilots if possible.
A bit offtopic - i probably need something more than FTDI cable to debug (and usbasp won't work here anyway)? Ebay search on "srm32 dev" shows many devices with TFT screen, but that's for developing new equipment. Do i need some advanced cable (or JTAG pins are allways available)?

EDIT: or equipment like this one? Pricey ;-)

You can get JLINK-EDU for around ~$60. You can get a STM32VLDiscovery or STM32F4Discovery boards for < $20 and use the STLink or STLinkV2 debugger that's part of them to develop. However, until I (or someone who knows what they're doing) gets one of these boards and traces the signals to make sure jtag or at least swd interface is actually available externally, I wouldn't rush out to buy any tools. If debugging the board means soldering wires to 0.5mm pitch tqfp, I won't bother with it. If you don't care to actually debug and just want to flash some software, it should support serial bootloader and you can just load some pre-built hex file from others.

Why not just redownload it from the site? They already included english version.

Thanks
It didn't work for me at the first time. Make sure to uninstall PC tool and reinstall it.....

Thank You timecop. Shipments from China usually take 5-6 weeks, so trying to pick anything i would need (will have vacation at end of 2012.01 - more time to spend thinking why my foamies crash so much ;-)
Soldering small pins shouldn't be a problem, but maybe i can get away with serial connection.
