[ECOS] A question for MBX860 target

["Zhang,Ye" <ye dot zhang at cmtsd dot mea dot com>]

Hello,
    I am new at eCos. I got a question about the connection to MBX860
board. I installed Linux 5.2 on my machine and downloaded the eCos
1.2.1. I have no problem for the build part.
I used the following command for the configuration for a PowerPC target,
the cogent board:
tclsh BASE_DIR/packages/pkgconf.tcl --target=powerpc --platform=cogent
--startup=ram

Then I followed the instructions:
1. powerpc-eabi-gdb -nw ...($BASE-DIR)/install/tests/kernel/bin_sem0
2. (gdb)set remotebaud 38400 
3. (gdb)target remote /dev/ttyS0
The program just hang up here. It looks like it has problem with the
connection.
My /dev/ttyS0 mode is rw-rw-rw. 
By the way, I can run the EPPCbug command, so there should be no problem
with the connection of the two machines. I also tried the simulator
mode. It worked fine. Can anyone explain what's wrong with my operation?
Thank you!
