# The erc32 console driver can operate in either polled or interrupt mode.
|
|
# Under the simulator (especially when FAST_UART is defined), polled seems
|
|
# to operate better. It is common for a task to print a line (like the
|
|
# end of test message) and then exit. In this case, the program returns
|
|
# control to the simulator command line before the program has even queued
|
|
# the output to the uart. Thus sis has no chance of getting the data out.

|
# SIMSPARC_FAST_IDLE (erc32_bsp)
|
|
# If defined, speed up the clock ticks while the idle task is running so
|
|
# time spent in the idle task is minimized. This significantly reduces
|
|
# the wall time required to execute the RTEMS test suites.

# If defined, enables work-around for bug 3.14 in FPU rev.B or rev.C
