[ECOS] GDB load error

[ECOS] GDB load error

[Piteir]

Hi,

I have build ecos configuration for Cirrus Logic
EDB7211
using "default" template.

with RAM startup and enable "Cirrus Logic EDB7XXX
serial port 1 driver"

then I compile hello example by typing:

	arm-elf-gcc -g -o hellog.exe
-I//c/ecos-work/hel_install/include hello.c
-L//c/ecos-work/hel_install/lib
-T//c/ecos-work/hel_install/lib/target.ld -nostdlib

then I convert to SREC format, using:

	arm-elf-objcopy -O srec hellog.exe hellog.srec

I load this using YMODEM, unfortunatelly when I type
'go' it just hang and nothing appears in my
HyperTerminal screen.

so, I tried again but this time using Redboot GDB-stub
by typing in my HyperTerminal:
	$Hc-1#09 and got respond +$OK#9a

I closed HyperTerminal and tried to debug it from
Cygwin but 
I got this error:

....
Remote debugging using com1
0xe0004c68 in ?? ()
(gdb) load
Loading section .rom_vectors, size 0x40 lma 0x20000
Loading section .text, size 0xfda8 lma 0x20040
Memory access error while loading section .text.
(gdb)


then I tried again, this time I just restart my board
and didn't enter to GDB-stub from Hyperterminal and
debug it. but this time I got error when I type
'continue', it just hanged there no respond at all

....
Remote debugging using com1

Start address 0x20040 , load size 67860
Transfer rate: 27144 bits/sec, 304 bytes/write.
(gdb) continue
Continuing.


anyone know what happen and what I should do to solve
this?

all I want just to see this example running in my
redboot

Thanks in advance

Try it with just the default configuration (no serial driver) just to be
sure. That should work.

Also if you built your own redboot you can use the redboot_ROM binaries for
the edb7211 at http://sources.redhat.com/ecos/boards/redbootbins/edb7211 to
be sure it isn't something with yours.

Looks like potentially flaky serial that's dropping characters. Try
reconfiguring for a lower baud rate.

Is this truly a 7211 (CL-7211) chip - and not a 7212 on a 7211-2 board?
If so, that chip is pretty slow.  Maybe you are having trouble keeping
up at 38400.  You might try rebuilding RedBoot to run at 19200 and then
see if GDB works with it.
