debug-arc

CLI reference

glasgow run debug-arc

Debug ARC processors via the JTAG interface.

The list of supported devices is:

• ARC6xx

• ARC7xx

There is currently no debug server implemented. This applet only allows manipulating Memory, Core and Aux spaces via a Python REPL.

usage: glasgow run debug-arc [-h] [-V SPEC] [--tck PIN] [--tms PIN]
                             [--tdi PIN] [--tdo PIN] [--trst PIN] [-f FREQ]
                             [--scan-ir-max-length LENGTH]
                             [--scan-dr-max-length LENGTH]
                             [--ir-lengths IR-LENGTH,...] [--tap-index INDEX]

-h, --help

show this help message and exit

-V <spec>, --voltage <spec>

configure I/O port voltage to SPEC (e.g.: ‘3.3’, ‘A=5.0,B=3.3’, ‘A=SA’)

--tck <pin>

bind the applet I/O line ‘tck’ to PIN (default: ‘A0’, optional)

--tms <pin>

bind the applet I/O line ‘tms’ to PIN (default: ‘A1’, optional)

--tdi <pin>

bind the applet I/O line ‘tdi’ to PIN (default: ‘A2’, optional)

--tdo <pin>

bind the applet I/O line ‘tdo’ to PIN (default: ‘A3’, optional)

--trst <pin>

bind the applet I/O line ‘trst’ to PIN (optional)

-f <freq>, --frequency <freq>

set TCK frequency to FREQ kHz (default: 100)

--scan-ir-max-length <length>

give up scanning IRs longer than LENGTH bits (default: 128)

--scan-dr-max-length <length>

give up scanning DRs longer than LENGTH bits (default: 1024)

--ir-lengths <ir-length,...>

set IR lengths of each TAP to corresponding IR-LENGTH (default: autodetect)

--tap-index <index>

select TAP #INDEX for communication (default: select only TAP)
