c7e7bd61b6 stlink: Do not wait for the reaction on the reset line. 
pc-hosted will abort, if the reset line is held externally to some value.
As assert is either driven or driven open drain, we can assume assert
immediate. For deassert, logic levels differences between the debugger and
the debuggee may apply and other ways to check the result are needed, like
CORTEXM_DHCSR_S_RESET_ST.

95053b3b4e Change the ST-Link SRST function to use libopencm3 helper functions and fix waiting for the pin-state, change init to use the SRST function for reset de-assertion 2018-09-05 20:28:02 +02:00

59e03dea27 Keep TMS floating until scanning. 
NRF5x shares nRST with SWDIO and otherwise does not run until scan is done.

6127a6431e stlink: Check nRST line level when setting SRST. 
Problem: On some boards flashing hanged.
Cause: Releasing SRST caused a slow rise of nRST and flashing
started while the target still was in reset.
Attention: platform_delay(ms) only resolved 0.1 s.
Nucleo-P boards have SRST unconnected to target nRST by default.

963df9febc stlink: Use common initialization and detect V2.1 boards. 
Factor out hardware revision detection, USB detach and power settings, as
all three program (bootloader, bmp and dfu-upgrade) need it.

cd1d72257f Cleanup of SRST handling. 
- Remove connect_assert_srst global.
- Attach functions always release reset.
- Platforms provide a method to poll the reset pin.
- Reset on scan is all internal to command.c
- Reset is released on a failed scan.  Fixes #111

4d4813de87 Clean up includes everywhere. 
All source files include general.h first and before anything else.
This inlcludes platform.h and platform_support.h
No header file needs to include to include any of these, but should include
any others needed for it's own declarations.

63bce97cbd PLATFORM_FATAL_ERRORs are now caught even when they happen in the 
initial JTAG scan that occours during platform_init.

Previously any fatal errors that occoured during this scan caused a
hardfault.
