RE: [ECOS] Should `$` be typed always to switch from Redboot to GDB Stub

["Andy Dyer" <adyer at righthandtech dot com>]

I would suggest using a serial port monitor program to watch what
both sides are sending.  A quick google on 'serial port monitor'
turned up a bunch of possibilities.

Redboot to GDB Stub
	
	

	Hi,
	    I have a ROM startup RedBoot running on my arm926ej-s target
	board. i m trying to test a hello RAM application on my target.
	after i typed in `$` at the RedBoot prompt, and disconnected the
	hyperterminal..i m expecting that the GDB Stub is now activated
	and i should be able to download by hello RAM application and
test
	it successfull.
	                 But, the GDB stub fails to respond and the
download
	fails..i get the following output:
	$ arm-elf-gdb -nw hello

	Malformed response to offset query, timeout

	how can i ensure the GDB Stub is workin fine. i m using
	ADS tool with JTAG interface to debug my code..but i m having
	no clue to which state the RedBoot has switched after typing
	`$` character at the RedBoot prompt..
	
	some one help me..
