Maybe this should be obvious, but I don't recall seeing it anywhere. Is
the "console" that referred to, the device that is attached to stdin,
stdout, stderr?
Can the console and dev/haldiag device share the same UART? On my ARM
LPC-2214 device I have one external port connected to the UART; the
other serial port is connected to an internal modem.
I'd like to make sure my serial operations are working on the easily
tested external device first (I have a terminal connected to that), before
I try to talk to the internal device.
Right now I am seeing some initial setup messages on /dev/haldiag. See
below.
However when my application calls printf at the top of cyg_user_start in
the example program TwoThreads, I get an ASSERT. The associated trace is
below. I think the "console" or stdout is not set up at all. What options
do I need to configure for that?
I thought my printf was working yesterday, and then it stopped. But I
don't recall changing anything so am puzzled.
I find the doumentation of the virtual vectors and ROM/RAM loads a bit
confusing. Right now I am loading what I would consider a "ROM" image into
RAM for testing using a JTAG debugger. There is not intended to be any
linkage to redboot, external monitors, etc as that is not needed; I can
load the program via JTAG. I am not sure this configuration is related to
my stdout problem.
Any feedback appreciated. Thanks!
