codewarrior tap and gdb

[ericmoors]

Hi,

I'm trying to setup a debug environment for the LS1046ARDB.

I've connected a codewarrior tap to it, which is directly connected via an ethernet connection(not USB) to my PC.

I have it configured with a fixed (private range, 10.1.42.1) IP address and can telnet to it just fine.

However when I try to use the gdbserver (proxy?) running on it I run into the following error:

(gdb) target remote 10.1.42.1:2345
Remote debugging using 10.1.42.1:2345
Protocol error: qXfer:features:read (target-features) conflicting enabled responses.
(gdb) set debug remote
Argument required (integer to set it to.).
(gdb) set debug remote 1
(gdb) target remote 10.1.42.1:2345
Remote debugging using 10.1.42.1:2345
Sending packet: $qSupported:multiprocess+;xmlRegisters=i386;qRelocInsn+#b5...Ack
Packet received: PacketSize=3fff;qXfer:auxv:read-;qXfer:features:read+;qXfer:libraries:read-;qXfer:memory-map:read-;qXfer:spu:read-;qXfer:spu:write-;QPassSignals-;
Packet qSupported (supported-packets) is supported
Sending packet: $Hg0#df...Ack
Packet received: OK
Sending packet: $qXfer:features:read:target.xml:0,fff#7d...Ack
Packet received:
Protocol error: qXfer:features:read (target-features) conflicting enabled responses.
(gdb)

So the proxy appears to claim it supports the features:read but when trying to read the (default) target.xml it does not respond?

What do I need to do to use the codewarrior tap with gdb?

please don't point me to this thread, because the steps don't work anymore (besides these are for PPC not an ARM board): https://community.nxp.com/message/916499

@Pavel  The links provided are broken. Can the support files be shared another way?

[wtoner]

can the gdb documentation, files and video etv be reposted? none of the links here work, they all go to file not found sorts of things.

Look at the following:

http://www.nxp.com/video/board-level-bringup-using-codewarrior-tap-and-gdb:BOARDLVL_CWTAPGDB_VID

It is too old demo project.

See documentation about GDB and CodeWarrior TAP in the attachment.

Source code is available using the following link:

Have a great day,

The video I cannot find at the NXP site, but I assume it is the same as this one: https://tune.pk/video/2538839/codewarrior-tap-and-gdb-board-level-bringup

and access to google drive is blocked by our company network :smileysad:

The attachment contains very useful information. The document describes on page 3 in the chapter "gdb and other usefull basics" the need for the target.xml which is supposedly downloadable from the old freescale site (http://freescale.com/CWTAP - downloads tab). However, on the NXP site I cannot find these anywhere.

Again on page 5 it mentions the target.xml that I am missing:

Where to get XML files with register information

• Freescale.com/CWTAP and then click on downloads TAB

• This will either be in a download that has lots of GDB technology OR we might put it in an XML/init file ONLY download specific to the chip and board.

• Just look for your Freescale processors model number and you should find what you need.

How can I generate/where can I get a target.xml for the LS1046A?

Hey,

I was wondering if you have successfully connected GDB remotely to the CodeWarrior Tap?
