Hi Andrew,
eCos has two serial device drivers for each board. The one in the hal
directory is a very simple polled IO, real time unfrendly, version
which is used for debugging. All diag_printf() output uses this driver
and also communcation to gdb.
Speaking of which, is there any problem in using diag_printf() in DSR's?
We were working on a USB driver, and getting very flaky operation
degrading to non operation of the driver, the cause couldn't be tracked
down, until we removed ALL the diag_printf(...), then the driver seems
to work reliably.
So I guess I'm asking should I feel comfortable the cause was using
diag_printf(..) in the DSR's, or should I be looking for problems in our
USB driver.
Thanks
Steve
