Not strictly required as we're using port A out of the box, but makes
for bad example code, when the syscfg clock is required for selectin
exti sources other than port A.
can fixes are compile tested only. I don't have those boards.
f3 i2c is tested on i2c and gives the same results
l1 low power demo seems to have been broken for some time already.
=> should be fixed, but not something I'm going to work on right now.
Instead of OOCD_SERIAL triggering an attempt to use a specific ftdi based
adapter, introduce common target/interface pairs, OOCD_INTERFACE and
OOCD_TARGET, and an override via OOCD_FILE allowing full control.
Further, attempt to connect to a running openocd instance to flash if possible.
This _will not_ work well if you have multiple openocd instances open at once,
but that's a rare use case.
Examples:
OOCD_INTERFACE=stlink-v2
OOCD_TARGET=stm32f0x
--> openocd ... -f interface/stlink-v2.cfg -f target/stm32f0x.cfg)
OOCD_FILE=board/ek-lm4f120xl.cfg
--> openocd ... -f $(OOCD_FILE) (ie, the variable is passed untouched)
As part of implementing this, correct variables that were always wrong, and
update the openocd flashing commands to use current commands.
Be specifically careful with the usb examples. There is likely some
breakage to be expected, not sure I updated all the drivers to the
correct types for the respective chips.
While some of the examples include a "board.ld" style file, some of them were
pointing to the libopencm3 provided chip specific ld scripts. When
TOOLCHAIN_DIR has been overridden, those paths were no longer valid/correct.
This is not specifically an L1 example, but it lives beside the L1 "usart"
example to show how easy it is to add semihosting support to existing code.
Tested with the by now relatively old g-a-e 2012q4 release and
OpenOcd 0.8.0-dev-00011-g70a2ffa (2013-05-14-19:41)
Replace includes of stm32/YY/xxxx.h with stm32/xxxx.h
Replace stm32/YY/nvic.h with cm3/nvic.h.
In some cases, the include list was resorted alphabetically when it was
complicated and I was reviewing them manually, but most of this was
automatically done.
