    How are you trying to build GBD? Using Yocto?

    It should already be part of the TI Yocto 'tisdk-default-image' type images, like this one...

    Hi Manu,

    I got a chance to double-check the WIC image for AM335x from SDK v9.1, and indeed GDB is there.

    a0797059@dasso:~/tisdk/am335x-evm/build (dev)
$ source conf/setenv

a0797059@dasso:~/tisdk/am335x-evm/build (dev)
$ unxz -k deploy-ti/images/am335x-evm/tisdk-default-image-am335x-evm.wic.xz

a0797059@dasso:~/tisdk/am335x-evm/build (dev)
$ wic ls deploy-ti/images/am335x-evm/tisdk-default-image-am335x-evm.wic
Num     Start        End          Size      Fstype
 1       1048576    135266303    134217728  fat16
 2     135266304   7696525311   7561259008  ext4

0797059@dasso:~/tisdk/am335x-evm/build (dev)
$ wic ls deploy-ti/images/am335x-evm/tisdk-default-image-am335x-evm.wic:2/usr/bin | grep gdb
   9897  100755 (1)      0      0   46768  9-Mar-2018 06:34 vgdb
   9070  100755 (1)      0      0   30608  9-Mar-2018 06:34 gdbus
   9068  100755 (1)      0      0    4587  9-Mar-2018 06:34 gdb-add-index
   9067  100755 (1)      0      0   5456152  9-Mar-2018 06:34 gdb
   9069  100755 (1)      0      0   314868  9-Mar-2018 06:34 gdbserver

    So I would highly suggest you move to v9.1., not just to get gdb but because this version is much newer/improved all around.

    If you must have gdb with SDK v8.2, I don't have this setup here, but having a quick look at the Yocto sources it looks like gdb is added by way of the tools-debug image feature (or the packagegroup-core-tools-debug package group). Try adding those to your image, like this:

    # Add to conf/local.conf (or extend, if it already exists)
EXTRA_IMAGE_FEATURES = "tools-debug"
