I'm thinking of making IMU on stm32 too. I have development board + JTAG debugger for it
I'm using KEIL uVision 3.
I have a plan to use:
3x magnetometer - HMC5843 20$ on digikey (but 50$ for the breakout board from sparkfun :)
3x accelerometer, 3x gyro IME-3000 + IDG-500, IDZ-500 ?$, 20$, 11$ (don't have them yet but I expect they will release IME-3000 soon)
The IMU should be below 100$ and with only 5 IC on a flat board.
How far you are with your IMU?
Have you been yo using ARM simulator ?
Today i spent part of the day programing the IMU and kalman filters for the smt32, soon i will publish it... =) just be patient please...
Actually now, i able to decode the accelerometers and gyros, using DMA and a super average to filter the noise.. I also setup all the Kalman skeleton but is not working yet =/, tomorrow if i have time, i will try to figure out whats going on, and tune up the system...
I have purchased 2 Keil STM32's and I am interested in contributing somehow. I am not as up to speed as you may be but I can give it a shot. Any good books that you can recommend to bring me up to speed? Jordi has been helping me but he is much better than I.
Hi Jordi, well at the moment everything went fine: I'm getting used with the stm32 functionalities, so far I've been using systick, PWM and UART. I plan on trying ADC next. Then, I'll work on designing a board with accelerometers, gyroscopes, 2 uarts (GPS & RF) and PWM outputs in a small package.

What is your progress? Do you have something to share ?
I'm spawning back the project, I've been doing schematic for a start, I'll publish them here as soon as I have finished.
