d6a314bed7 efm32: make all interrupts usable in vector table 
* define weak symbol for ${irq_name}_isr
* put them in the rom vector table
* declare reset_vector weak in case someone wants to insert code there
* remove null_handler (null handlers should be only requested
  explicitly, and finding out why the chip gets stuck is easier than
  determining whether or not a no-op interrupt handler was executed)

2275ed7b0c overhauled documentation 
includes minor refactoring in example code and modification of how the
generic and the tinygecko specific vector.h go together (bringing it in
line with stm32/f1's memorymap.h)

2180a02e2f first attempt at porting libopencm3 to energymicro 
unless sources are explicitly given, the linker scripts and make files
were copied over from the stm32/f1 port.

1a3ad6e998 Added the entry point definiton to all stm32 linker scripts. This allows gdb to reset the target correctly on exit. 2012-02-11 22:24:41 -08:00

3e47a46c5c Fix numerous bugs in NVIC convenience functions, doing an |= on a clear register will clear ALL currently enabled irqs, not just the one you specified and other things of that sort. Also changed to support the full range of irq numbers supported by ARMv7M, not just the first 68 used in the STM32F1 series. 2012-02-06 23:08:07 +01:00

651917aeb4 Added USB example for stm32f4. 
Moved clock enable for OTG_FS back into applications.  This and gpio config
are the only differences between f107 and f2xx/f4xx.

c6f30043fd Added UART4 and UART5 gpio definitions for stm32f1. Also corrected the naming everywhere. Both peripherals are UARTS not U_S_ARTS. 2011-11-16 18:17:56 -08:00

30e188cf07 Only allow one packet in TX fifos. 
This fixes a problem where packets were written too quickly.
The hardware disabled the endpoint after the fist packet is sent,
and others just waited in the queue.

7546ad9736 Fixed loading of .data in linker scripts. 
This fixes a problem where the linker included some padding
bytes between the end of the .text section (_etext) and the
start of the .data section.

The C runtime copies from _etext, so all static initialised data
was corrupted.  This change forces the .data section to be written
at _etext to avoid this problem.
