* altos: Use flash loader on all STM productsKeith Packard2013-05-07
| | | | | | Includes the boot chain stuff Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Use separate exception stack on STM32LKeith Packard2013-05-07
| | | | | | | | This reserves 512 bytes of memory for a stack, then makes sure that exceptions continue to use that stack while processes use the per-task stack. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Place STM config values at fixed addresses for re-useKeith Packard2012-07-17
| | | | | | | | Just like cc1111, stick the serial number and radio calibration values at known fixed addresses so that when re-flashing the board, we can go find the existing values. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/stm: Force STM stack to start at the top of RAMKeith Packard2012-07-14
| | | | | | | Using a fixed size means crashing if there's not enough space for that, or wasting memory if there's too much. Signed-off-by: Keith Packard <keithp@keithp.com>
* Use -Os for STM apps. Fix altos.ld to matchall .rodata* sectionsKeith Packard2012-03-28
| | | | | | | | Without .rodata*, it would stick the flash copy of the data on top of any further .rodata* sections. Fortunately, the linker catches that and complains... Signed-off-by: Keith Packard <keithp@keithp.com>
* Add STM platform and stm-bringup demo programKeith Packard2012-03-28
The stm-bringup doesn't run altos, it just initializes the device and writes stuff over a serial port. Works on the STM32L Discovery board at least, should do stuff on other boards too. Signed-off-by: Keith Packard <keithp@keithp.com>
