From 52d4ba3467134a1489583dbb6d6de3002f0f76fa Mon Sep 17 00:00:00 2001 From: Mathias Kuester Date: Sun, 14 Feb 2010 12:59:10 -0800 Subject: [PATCH] fix crash with DSP563XX When a DSP563xx-aware GDB asks OpenOCD for target registers, the result should be a GDB with register data ... not an OpenOCD crash. (Note that mainline GDB doesn't currently support this core, so for now, this requires a GDB with FreeScale patches.)
