Hello,
i have a “SABRE Board for Smart Devices Based on the i.MX 6 Series”. And I tried to get OpenOCD to work with it.
This is my OpenOCD configuration file for the i.MX6. Which is included in OpenOCD v0.7-dev.
scripts/target/imx6.cfg
# Freescale i.MX6 series single/dual/quad core processor
if { [info exists CHIPNAME] } {
set _CHIPNAME $CHIPNAME
} else {

}

if { [info exists DAP_TAPID] } {
set _DAP_TAPID $DAP_TAPID
} else {
set _DAP_TAPID 0x4ba00477
}
jtag newtap $_CHIPNAME dap -irlen 4 -ircapture 0x01 -irmask 0x0f \
-expected-id $_DAP_TAPID
# SDMA / no IDCODE
jtag newtap $_CHIPNAME sdma -irlen 4 -ircapture 0x00 -irmask 0x0f
# System JTAG Controller
if { [info exists SJC_TAPID] } {
set _SJC_TAPID SJC_TAPID
} else {
set _SJC_TAPID 0x0191c01d
}
set _SJC_TAPID2 0x2191c01d
jtag newtap $_CHIPNAME sjc -irlen 5 -ircapture 0x01 -irmask 0x1f \

set _TARGETNAME $_CHIPNAME.cpu.0
target create $_TARGETNAME cortex_a8 -chain-position $_CHIPNAME.dap \
-coreid 0 -dbgbase 0x82150000
# some TCK cycles are required to activate the DEBUG power domain
jtag configure $_CHIPNAME.sjc -event post-reset "runtest 100"

I tested it with Openocd 0.6.1 and now I am on Open On-Chip Debugger 0.7.0-dev-00204-g1da9e59 (2013-03-27-09:22)
I know i allready posted it on the iMX Forum but did not got any response…
Do you have any idea what’s the problem? If you need further information or if i did something wrong please let me know!
Thank you! I hope you can help me!

Hello Matt,
Have you been able to verify that the openocd-usb-hs is working OK?
-Hugh
(apologies if it is built into the Sabre - too lazy to research today.)
Hello Hugh,
thank you for your reply. The openocd-usb-hs is working with other Hardware.
The Output with the Sabre is very confusing to me, because there is absoulute no response from the board, if i am right.
The Board is only resetting but after that nothing happens.
Regards
MaTT
Matt,
I would try two things:
use a fixed jtag clock rather than adaptive, starting slow, eg. adapter_khz 100
use the newer ftdi driver, configure OpenOCD with --enable-ftdi. It uses libusb-1.0 or libusbx and is the preferred driver moving forward.
The only other change to your config is to the interface script used, note the added ftdi directory.
scripts/interface/ftdi/openocd-usb-hs.cfg
Cheers

Hello Spen,
Hello Spen,
Thank you for your quick answer.
I allready tried it with different adapter_khz speeds but I had no success.
this is how i set up openocd

It can be a very stupid failure… I am not a professional on OpenOCD/Embedded World (just a beginner but I am interested in learning).
Thank you for your help
MaTT
Please try with latest master, eg, ‘git checkout master’ rather than use 0.6.1 release.
Also enable full debug log (-d3) and set jtag speed manually, disable rclk.
I would also disable using the older ftdi driver - remove ‘–enable-ft2232_libftdi’ from configure line.
Spen
Thank you, I read a bit through the output but I do not know what I am searching for…

Thank you for your help

Can you disable rclk please and rerun, also try connecting via telnet and issue ‘reset halt’.
The support for this target has only just been added, so it may be worth asking on the [openocd-devel mailing list. You will need to subscribe to post.
As a side note you should really sort out your permissions (udev etc), so sudo is not required.

Hello Spen,
Thank you for your quick answer.
I allready tried it with different adapter_khz speeds but I had no success.
this is how i set up openocd
ft2232 mode
sudopenocd -f /usr/local/share/openocd/scripts/interface/openocd-usb-hs.cfg \
-f /usr/local/share/openocd/scripts/target/imx6.cfgOpenOCD: Bug Reporting
nothing happens..
ftdi mode
sudo openocd -f /usr/local/share/openocd/scripts/interface/ftdi/openocd-usb-hs.cfg OpenOCD: Bug Reporting
nothing happens..
It can be a very stupid failure.. I am not a professional on OpenOCD/Embedded World (just a beginner but I am interested in learning).
Thank you for your help

Not many “beginners” drop $500 on a dev board. I have one of these, but we aren’t using openocd.
The app guys using kdevelop with gdb over the console/network for now. Its simple enough once the environment works.
Also other work intrudes,and I likely won’t be back on this board for a few weeks.
What ocd hardware are you using? arm-usb from olimex?
Hello,
thank you for your hints/advices! I connected a Logic Analyzer to the JTAG Port. In my opinion it is not normal that the RESET stuck to ground, isn’t it?

How do i disable rclk?

First of all! Thank you very much for your help!!!
I have “solved” the Problem! I removed the RESET wire between openocd-usb and the target board. Now i have basic jtag access. But i do not know why the RESET stuck to ground? Any Ideas?
Cheers
MaTT
Matt,
Glad it is partially working.
rclk is disabled by setting a adapter speed, eg. replace jtag_rclk 1000 with adapter_khz 100 as a start.
The speed can be changed back once we have proved rclk is not causing issues.
As to why the srst is causing issues i have no idea, the adapter may be damaged or the driver may have issues.
I cannot find any info on this adapter so not much i can do to help further.
To test, the srst lines can be manually changed, eg.
# jtag_reset trst srst
jtag_reset 0 1 # asserts srst
jtag_reset 0 0 # releasees srst
Spen
Thanks Span,
this is the output from jtag_rest. If i test the openocd-usb-hs debugger with a other dev-board the RESET works fine. So it is only a phenomen of this constellation (software/hardware).
openocd-usb-hs with i.MX6qsabresd
> jtag_reset 0 1
BUG: can't assert SRST
in procedure 'jtag_reset'
Regards
MaTT
To use jtag_reset you do need a srst fitted and configured, eg. reset_config srst_only
Spen
Thanks Span,
I added this to my configuration:
reset_config srst_only
Now if i try there is no failure, but also no output on the digital pin!
> jtag_reset 0 0
> jtag_reset 0 1
> jtag_reset 1 0
> jtag_reset 1 1

I had the same problem. It turned out that pins 6 and 7 of the wandboard’s jtag header were shorted out when I soldered in the header.
