Firmware for the Black Magic Debug Probe.
|
|
|
|
The Black Magic Probe is a modern, in-application debugging tool for
|
|
embedded microprocessors. It allows you see what is going on 'inside' an
|
|
application running on an embedded microprocessor while it executes. It is
|
|
able to control and examine the state of the target microprocessor using a
|
|
JTAG or Serial Wire Debugging (SWD) port and on-chip debug logic provided
|
|
by the microprocessor. The probe connects to a host computer using a
|
|
standard USB interface. The user is able to control exactly what happens
|
|
using the GNU source level debugging software, GDB.
|
|
Serial Wire Output (SWO) allows the target to write tracing and logging to the host
|
|
without using usb or serial port. Decoding SWO in the probe itself
|
|
makes [SWO viewing as simple as connecting to a serial port](https://github.com/blacksphere/blackmagic/wiki/Serial-Wire-Output).

BLACKMAGIC
|
|
==========
|
|
|
|
You can also build blackmagic as a PC hosted application
|
|
"make PROBE_HOST=hosted"
|
|
|
|
This builds the same GDB server, that is running on the Black Magic Probe.
|
|
While connection to the Black Magic Probe GDB server is via serial line,
|
|
connection to the PC-Hosted GDB server is via TCP port 2000 for the first
|
|
GDB server and higher for more invokations. Use "tar(get) ext(ented) :2000"
|
|
to connect.
|
|
PC-hosted BMP GDB server can talk to the Black Magic Probe itself,
|
|
ST-LinkV2 and V3, CMSIS-DAP, JLINK and FTDI MPSSE based debuggers.
|
|
|
|
When connected to a single BMP supported probe, starting "blackmagic" w/o any
|
|
arguments starts the server. When several BMP supported probes are connected,
|
|
their types, position and serial number is displayed and the program exits.
|
|
Add "-P (position)" to the next invokation to select one.
|
|
|
|
PC hosted BMP also allows to flash, read and verify a binary file, by default
|
|
starting at 0x08000000. The "-t" argument displays information about the
|
|
connected target. Use "-h " to get a list of supported options.
