Adding 3rd-party tool chain by locating its *gdb.exe

[asmodyne]

Hello !

I’m trying to cross-compile some projects for a CortexA53  aarch64 target ( namely, a Samsung S5P6818 octo-core board, the NanoPi Fire3, running a lightweight ubuntu ditrib ).
So I downloaded ARM’s official GNU toolchain,  version 7.2.1 20170904, hoping to user the -Aarch64 option for armv8 cores.

Here is the *gdb  executable : (attachment 1)

 

But when I specify its arm-none-eabi-gdb.exe location, the wizard brings me back to a no-toolchain-selected situation : (attachment 2)

Even weirder, the toolchain appears in VisualGDB’s installed packages list : (attachment 3)

What am I doing wrong here ?

Hi,

The normal ARM cross-toolchain only works for barebone devices (i.e. without Linux). If you would like to target Linux, you would need a special toolchain that is built to match your Linux distro and configuration. Please check your device vendor’s site whether they provide such a toolchain. If not, we could build one for you as a part of our custom toolchain building service. Please contact our sales if you would like to get a quote.

The vendor (FriendlyARM) do supply a toochain, but for  x64 linux hosts, and buggy as hell (wrong headers, implicit cast of pointers to int32 everywhere… -_-

And I’m afraid asking for a custom toolchain is way beyond my budget ! :'(

I just hate FriendlyARM… disappointed in 2008, disappointed in 2018 again… 10 years and still not an ounce of professionalism.
It’s a if they get SOCs from a tipped-over truck and slap them onto PCBs.

Hi,

Sorry, getting a toolchain right is often tricky, that’s why we provide it as a paid service. The good news is that 64-bit ARM boards are becoming more mainstream (Raspberry Pi 3 is actually 64-bit, although the Raspbian distro is 32-bit), so we may eventually add a free 64-bit cross-toolchain if one of the boards becomes really popular.

Yes, the aarch64 is spreading ! =)
And both BCM2837 and S5P6818 share Cortex A53 cores, so it shouldn’t be long before I get a quick fix to my predicament.

Right now, I’ve opted to remote-compile my code directly on the target.  Its eight cores might be able to do the job quickly. =P

I almost forgot to Thank You ! ^_^ !
