olimex-arm-usb-tiny-h with new hardware

Development Boards MicroMod
1

Looking for advice on two things:

a) verifying my olimex-arm-usb-tiny-h is functioning properly and

b) configuring for hardware I don’t see explicitly listed in the scripts.

I’m trying to get openocd working with a CEL ZFSM-201-1 eval board. The board has a 20 pin jtag connector for an mc13224 microcontroller (arm7tdmi).

I have tried Windows XP and MacOSX hosts. On windows I have used the openocd provided online (https://www.olimex.com/Products/ARM/JTA … e_v1.1.zip) by Olimex. Not sure why but this “new” online package uses openocd 0.4.0. On MacOSX I have built things from very recent archives and checkouts. The end results are pretty much the same on both host platforms and whether I use configs like the redwire ones and the mc13324v.cfg or a basic setup to try and discover TAP information.

For my example, I will use the “autoprobe” on MacOSX. This was built with: “–enable-maintainer-mode --enable-ft2232_ftd2xx” and the 1.2.2 drivers (2012/10/30) from (http://www.ftdichip.com/Drivers/D2XX.htm) installed. For an openocd.cfg (as I believe suggested by 10.7 of http://openocd.sourceforge.net/doc/html … eclaration):

source [find interface/olimex-arm-usb-tiny-h.cfg]

reset_config trst_and_srst

jtag_rclk 8

Running with:

openocd -c “debug_level 3” -f openocd.cfg

gives the log as reproduced below. The first error is “Error: 111 26484 ft2232.c:591 ft2232_read(): couldn’t read enough bytes from FT2232 device (0 < 81)” and I have seen this on windows as well.

If include the mc13224v.cfg, and issue a subsequent “scan_chain” I see:

TapName Enabled IdCode Expected IrLen IrCap IrMask

0 mc13224.cpu Y 0x00000000 0x1f1f001d 4 0x01 0x0f

Any suggestions?

OpendOCD has a lot of churn and unfortunately the developers have no problems breaking stuff along the way.

The last version I know that worked is noted here:

http://mc1322x.devl.org/openocd.html

0.4.0-rc1-dev-00143-g4960c90 (2010-01-22-19:26)

That’s probably your easiest way moving forward with this.

@malvira - sometimes targets get broken - mainly because we do not have access to all targets supported in OpenOCD.

If you are willing to build OpenOCD then get the latest from sf and use the new ftdi driver - built using --enable-ftdi

The new driver uses libusb-1.0 rather then the older libusb-0.1.

To use the new ftdi driver the only other change is the adapter cfg:

source [find interface/olimex-arm-usb-tiny-h.cfg]        // old driver
source [find interface/ftdi/olimex-arm-usb-tiny-h.cfg]  // new ftdi driver

I would use the mc13224v.cfg config as it look like it should work.

Cheers

I rebuilt with --enable-ftdi and got different results.

  • the telnet server accepts connection but never responds to commands. Because of this I added an explicit telnet_port (no effect), specified the mc13224v.cfg, and added a scan_chain.

  • When the scan chain executes it reports an IdCode of 0x0000000 – not what I would expect. That said, I would trust the results more if the entire config had been processed and I was executing scan_chain from the telnet port.

See below for the log.

On a different note… any thoughts on regression tests for OpenOCD? I’m sure key users (adapter makers) would be willing to set up cron jobs that would pull source, build, run at least a minimal/status test suite for the adapters/boards they have, and post results.

I do not see anywhere in the log where the actual scan chain is actually scanned by your adapter.

Could you give me you exact cmd line/cfg used.

For info the default telnet port is 4444.

With regards to a testsuite it has been thought about but has never gone any further. Any ideas are always welcome.

Cheers

Uh… I just looked at that last trace and I don’t know where that came from. Sorry about that.

I just tried again and the telnet port is now working. And… the led on the adapter is blinking (as opposed to solid). Unfortunately the scan chain still reports 0x0 for the IdCode.

Here is a copy and paste of my openocd.cfg:

debug_level 3

source [find interface/ftdi/olimex-arm-usb-tiny-h.cfg]

reset_config srst_only srst_open_drain
jtag_ntrst_delay 200

#jtag_rclk 0
jtag_rclk 8

source [find target/mc13224v.cfg]

scan_chain
telnet_port 4444

I also issued a “scan_chain” from the telnet port at the end of the log.

To avoid cluttering this list with a log, you can find it here:

Thanks,

Jonathan,

OpenOCD has as such two internal states, config and exec.

Certain cmds will only run in exec mode, this is after init is done.

scan_chain for some reason is configured to execute in any mode (possible bug), however the scan chain is not ready until init has been executed.

So in your case you need to annually issue init if you are going to use scan_chain in your config.

...
source [find target/mc13224v.cfg]
# slow jtag down for testing
adapter_khz 10
# manually call init
init
# now we can safely call exec cmds
scan_chain

The other problem is that the id is not correctly read, it may be worth disabling rclk for testing - see adapter_khz above.

I also had a look at the user guide for the eval kit you are using, this suggests that srst and trst are not connected, if this is the case then you need to remove the reset_config setting.

The srst and trst may be worth checking on the actual board, as the pinout in the user guide does contain typos. pin15 is srst not DBGRQ.

If srst is not connected then the only way for OpenOCD to reset the target is by using soft_reset_halt cmd - i do wish board manufacturers would not do this.

Cheers

Spen

The documentation for the JTAG header on the board is simply wrong. I traced things thru the board art and DBGRQ and DBGACQ are not present, and “RESETB” is connected to pin 15 (erst). Worse still, the latest art available from the vendor site is for for “ISSUE ES2” and my boards are labeled as “ISSUE ES3-X2” so I’m still a little worried.

My previous telnet issue has gone away. I’m assuming I must have had a hung port or something.

Here’s the latest…

If I start openocd before I apply board power switch, it comes up, I can perform scan_chain via the telnet port, and I get the correct IdCode back for the mc13324 TAP. If I start openocd after I’ve applied power, the IdCode reports as 0x0.

In all cases a “halt” appears to time out (either before or after power is applied).

With the config:

debug_level 3
source [find interface/ftdi/olimex-arm-usb-tiny-h.cfg]
reset_config srst_only srst_open_drain
jtag_ntrst_delay 200
#jtag_rclk 0
jtag_rclk 8
adapter_khz 10

source [find target/mc13224v.cfg]

Here are the logs:

http://www.vivistar.com/arm/ocdlog_2013 … thenon.txt

http://www.vivistar.com/arm/ocdlog_20130111on.txt

I have noticed that “reset” resets the board and it runs its normal program (blinky lights). However, halt really is failing because attempting to print any register gives and error as indicated below.

> reset

The “all zeroes” got me to look back at the openocd log:

So I’m guessing something with the board powered is messing up the JTAG connection? I’ll start checking jumpers but I don’t remember a “remove this jumper to enable JTAG operation.”

10

[Despite my success please read on for another question.]

Insanity!

My guess is that the development board was provided with a FLASH program in “secure” mode. The boot process of the mc13224 doesn’t enable the JTAG interface if the FLASH is “secured.” The board has a couple of jumpers to nuke the FLASH. I did that and…

Now I can start openocd with the board already on, it correctly reads the IdCode, I can scan_chain, halt, reset, and I presume most other things.

Not sure why you would provide a development board “secured.” Maybe it is a default behavior of the FreeScale non jtag programming tool. Regardless, I think I can start making progress now.

I have one more question. While digging thru the details of this development board, I found this little snippet in the schematic:

http://www.vivistar.com/arm/no_rtck.png

Digging out my jewelry loupe and looking at the teeny surface mounts for R3 and R4, R3 is simply not present. Any one know what a resistance value of “NP” for R4 would be? Not Provided? So… RTCK is not currently connected to the JTAG connector.

Other than providing another unencumbered ADC channel, any ideas why they would defeat RTCK?

Is it worth hooking up RTCK?
