+
+This repository contains assorted example projects for libopencm3.
+
+The libopencm3 project aims to create an open-source firmware library for
+various ARM Cortex-M3 microcontrollers.
+
+For more information visit http://libopencm3.org
+
+The examples are meant as starting points for different subsystems on multitude
+of platforms.
+
+Feel free to add new examples and send them to us either via the mailinglist or
+preferably via a github pull request.
+
+Usage
+-----
+
+The makefiles are generally useable for your own projects with
+only minimal changes for the libopencm3 install path (See Installation)
+
+For flashing the 'miniblink' example (after you built libopencm3 and the
+examples by typing 'make' at the top-level directory) onto the Olimex
+STM32-H103 eval board (ST STM32F1 series microcontroller), you can execute:
+
+ $ cd examples/stm32/f1/stm32-h103/miniblink
+ $ make flash
+
+The Makefiles of the examples are configured to use a certain OpenOCD
+flash programmer, you might need to change some of the variables in the
+Makefile if you use a different one.
+
+You can also flash manually like this:
+
+ $ openocd -f interface/jtagkey-tiny.cfg -f target/stm32f1x.cfg
+ $ telnet localhost 4444
+ > reset halt
+ > flash write_image erase foobar.hex
+ > reset
+
+Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or
+replace "stm32f1x.cfg" with your respective config file. Replace "foobar.hex"
+with the file name of the image you want to flash.

-
-This repository contains assorted example projects for libopencm3.
-
-The libopencm3 project aims to create an open-source firmware library for
-various ARM Cortex-M microcontrollers.
-
-For more information visit http://libopencm3.org
-
-The examples are meant as starting points for different subsystems on multitude
-of platforms. If you're just looking to test your build environment and hardware,
-the [libopencm3-miniblink](https://github.com/libopencm3/libopencm3-miniblink) 
-may be more useful, as it covers _many_ more boards, but it is much more limited.
-
-Feel free to add new examples and send them to us either via the mailinglist or
-preferably via a github pull request.
-
-## Usage
-
-You _must_ run "make" in the top level directory first.  This builds the
-library and all examples.  If you're simply hacking on a single example after
-that, you can type "make clean; make" in any of the individual project
-directories later.
-
-For more verbose output, to see compiler command lines, use "make V=1"
-For insanity levels of verboseness, use "make V=99"
-
-The makefiles are generally useable for your own projects with
-only minimal changes for the libopencm3 install path (See Reuse)
-
-## Make Flash Target
-
-Please note, the "make flash" target is complicated and not always self-consistent.  Please see: https://github.com/libopencm3/libopencm3-examples/issues/34
-
-For flashing the 'miniblink' example (after you built libopencm3 and the
-examples by typing 'make' at the top-level directory) onto the Olimex
-STM32-H103 eval board (ST STM32F1 series microcontroller), you can execute:
-
-    cd examples/stm32/f1/stm32-h103/miniblink
-    make flash V=1
-
-The Makefiles of the examples are configured to use a certain OpenOCD
-flash programmer, you might need to change some of the variables in the
-Makefile if you use a different one.
-
-To program via a Black Magic Probe, simply provide the serial port, eg:
-
-    cd examples/stm32/f1/stm32-h103/miniblink
-    make flash BMP_PORT=/dev/ttyACM0
-
-To program via texane/stlink (st-flash utility), use the special target:
-
-    cd examples/stm32/f1/stm32vl-discovery/miniblink
-    make miniblink.stlink-flash
-
-If you rather use GDB to connect to the st-util you can provide the STLINK\_PORT
-to the flash target.
-
-    cd examples/stm32/f1/stm32vl-discovery/miniblink
-    make flash STLINK_PORT=:4242
-
-## Flashing Manually
-You can also flash manually. Using a miriad of different tools depending on
-your setup. Here are a few examples.
-
-### OpenOCD
-
-    openocd -f interface/jtagkey-tiny.cfg -f target/stm32f1x.cfg
-    telnet localhost 4444
-    reset halt
-    flash write_image erase foobar.hex
-    reset
-
-Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or
-replace "stm32f1x.cfg" with your respective config file. Replace "foobar.hex"
-with the file name of the image you want to flash.
-
-### Black Magic Probe
-
-    cd examples/stm32/f1/stm32vl-discovery/miniblink
-    arm-none-eabi-gdb miniblink.elf
-    target extended_remote /dev/ttyACM0
-    monitor swdp_scan
-    attach 1
-    load
-    run
-
-To exit the gdb session type `<Ctrl>-C` and `<Ctrl>-D`. It is useful to add the
-following to the .gdbinit to make the flashing and debugging easier:
-
-    set target-async on
-    set confirm off
-    set mem inaccessible-by-default off
-    #set debug remote 1
-    tar ext /dev/ttyACM0
-    mon version
-    mon swdp_scan
-    att 1
-
-Having this in your .gdbinit boils down the flashing/debugging process to:
-
-    cd examples/stm32/f1/stm32vl-discovery/miniblink
-    arm-none-eabi-gdb miniblink.elf
-    load
-    run
-
-### ST-Link (st-util)
-
-This example uses the st-util by texane that you can find on [GitHub](https://github.com/texane/stlink).
-
-    cd examples/stm32/f1/stm32vl-discovery/miniblink
-    arm-none-eabi-gdb miniblink.elf
-    target extended-remote :4242
-    load
-    run
-
-## Reuse
-
-If you want to use libopencm3 in your own project, the _easiest_ way is
-to use the template repository we created for this purpose.
-
-See https://github.com/libopencm3/libopencm3-template

+SCR=128, CPSDVSR=2 => 288MHz / (2*(128+1)) = 1.116MHz
