Hard Hangs

Software debug over JTAG uses the CPU as a "debug agent" that acts under control of the debugger. This means the CPU must be able to fetch code and execute it, and communication with other system agents (e.g. memory controller, IO devices) must be possible. If there is a hard-hang on the CPU or any required resource then the debugger capabilities will degrade or simply not function.

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
