[Lazarus] Gdb and openocd via lazarus

[Justin Smyth]

Thanks Michael


I got better results from using the GDB from the tool chain binaries from
linaro.

Is it normal for TUI not to be supported in the arm eabi version ?

I can now start openocd8 , and start gdb and I see both of them talk to each
other ( I want to see gdb connect correctly then I will move onto getting
lazarus to connect once I have it working in two dos prompts on my windows
vm )

My open ocd configuration file looks like this ( does this look right ?
anything missing  or do I need to change anything ? )


source [find interface/stlink-v2.cfg]
set CHIPSERIES lpc1300
set TRANSPORT hla_swd
set CPUROMSIZE 0x8000
set CPURAMSIZE 0x2000
source [find target/lpc1343.cfg]

init
reset init

flash write_image erase unlock myprogram.elf 0 elf

reset run
reset init


Kind Regards


Justin

There's an excellent Page on using gdb with freepascal on the wiki:

http://wiki.lazarus.freepascal.org/GDB_Debugger_Tips,

when you scroll down there's a list of recommended gdb versions.

Rebuilding gdb from source is peace of cake on linux and mac, I never 
really tried it on a windows machine , but this link should help:

.html

or have a look at the linaro toolchain, they also have a lot of 
different precompiled versions for windows, their builds:

https://releases.linaro.org/14.05/components/toolchain/binaries

When you start at https://releases.linaro.org/ you can see all the 
different versions available.
