There is no aarch64-unknown-linux-gnu-gdb in gcc-4.8.5-aarch64 toolchain

Hi,

I’d like to use KGDB in TX2 board. so i have searched how to use KGDB on ARMv8 platform.

As you know, there is a stage that connect gdb to kdgb to use KGDB as follows.

host side

aarch64-unknown-linux-gnu-gdb vmlinux set remotebuad 115200
$ target remote /dev/ttyUSB0

But, there is no aarch64-unknown-linux-gnu-gdb in gcc-4.8.5-aarch64 toolchain.

Is my opinions wrong?? plz give me your opinions.

Thanks,
Doohan93

Hi doohan93,

Yes, we don’t provide the pre-built aarch64-unknown-linux-gnu-gdb in the tool chain.

Could you check the toolchain source and see if there is gdb?

Btw, you can use other newer tool chains from Linaro for gdb and those will also work, e.g., the 5.3 series.
