This section discusses debugging issues related to the interaction of the host
code and the accelerated kernels. Problems with these interactions manifest as issues
such as machine hangs or application hangs. Although the GDB debug environment might
help with isolating the errors in some cases (xprint),
such as hangs associated with specific kernels, these issues are best debugged using the
dmesg and xbutil
commands as shown here.
If the process of hardware debugging does not resolve the problem, it is necessary to perform hardware debugging using the ChipScope feature.
