ARM Cortex-M GDB server with device squirrel scripting support
EBlink features:
- GDB server with flash caching, with EmBitz live variables/expression support!
- Stand alone flashing tool
- Device support by squirrel scripting, flash algorithm, device reset strategy etc
- Multiple interfaces (right now STlink)
Usage: eblink <options>
-h, --help Print this help
-g, --nogui No GUI message boxes
-v, --verbose Specify generally verbose logging
-D <script>, --device <script> Select the device script <>.script
-T <options>, --target Select target(optional)
-I <options>, --interf Select interface
-F <options>, --flash <options> Target image flashing
-G [options], --gdb <options> Launch GDB server
--device and --interf are mandatory, normally combined with --flash or/and --gdb
==== Interfaces
name: CMSIS-DAP - ARM debug protocol driver Usage -I cmsis-dap[,options]
<not yet implemented>
name: ST-link - STmicro V2 interface driver Usage -I ST-link[,options]
rconnect : Connect under reset
speed=nnn : Interface speed
swd : use SWD (default)
jtag : use Jtag
device=<usb_bus>:<usb_addr> : Select probe explicit
e.g. -I ST-link,rconnect,speed=3000
==== Flash loader Usage -F [options]
erase : Chip erase the flash
verify : Verify flash after upload
run : Start image after upload
file=<file> : Load the file, <file>.hex = Intel HEX format
<file>.srec = Motorola srec file format
Default = ELF file format
e.g. -F file=test.elf
-F verify,run,file=test.srec
-F erase
-F erase,run,file=test.hex
Default (without erase) only modified sectors are (re)flashed.
==== GDB server Usage -G [options]
S : Shutdown after disconnect
nc : Don't use EB-link flash cache
port=ppp : Select different TCP port, default 4242
address=x.x.x.x : Select different listen address, default 0.0.0.0
e.g. -G S,nc
Examples:
Connect STmicro device with STlink on GDB server
=> eblink -I st-link -D stm32-auto -G
Connect silabs device with STlink on bus 2:4 and launch the GDB server on port 4243:
=> eblink -I st-link,device=2:4 -D silabs-auto -G port=4243
Flash STmicro device with STlink and run
=> eblink -I st-link -D stm32-auto -F verify,run,file=release.elf,
