| 00:00.10 | roxfan | and the other one? |
| 00:00.10 | Circuitsoft | # Id of device #1: 0x25A6802B |
| 00:02.13 | roxfan | hmm this one looks like arm but i seem to get arm10... |
| 00:02.42 | Circuitsoft | The chip is an NXP cellular baseband processor. |
| 00:02.59 | Circuitsoft | 104Mhz Arm946ejs |
| 00:03.33 | roxfan | http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/3843.html |
| 00:04.33 | roxfan | i wonder if there was a glitch |
| 00:04.42 | roxfan | and it should read 2596802B |
| 00:05.01 | roxfan | no wait... that's still not 946 |
| 00:05.04 | Circuitsoft | No chance the other one is the ARM? |
| 00:05.14 | roxfan | pretty unlikely |
| 00:05.26 | Circuitsoft | http://www.nxp.com/#/aip/aip=[aip=429]|pp=[t=aip,i=429] |
| 00:05.28 | roxfan | that technote says arms should have 0 in bit 27 |
| 00:05.58 | roxfan | do you have a datasheet? |
| 00:06.10 | Circuitsoft | no. |
| 00:06.14 | roxfan | pity |
| 00:06.24 | Circuitsoft | The link I just sent you is the closest thing I have to a datasheet. |
| 00:09.51 | Circuitsoft | And, now I feel dumb. |
| 00:10.16 | Circuitsoft | The "JTAG Debug Application Note" from the module provider includes an openocd config file in the pdf. |
| 00:10.39 | roxfan | heh |
| 00:10.46 | Circuitsoft | Granted, it makes the assumption of an "Amontec JTAGkey A", but that's easy enough to change. |
| 00:11.03 | roxfan | manufacturer id matches 00000010101 philips Philips Semi. (Signetics) |
| 00:11.32 | roxfan | hmm, although both ids have the same manuf id... |
| 00:11.46 | roxfan | so i guess dsp is also from philips? |
| 00:11.50 | roxfan | er, nxp |
| 00:12.01 | Circuitsoft | It's a single-chip with two devices. |
| 00:12.05 | roxfan | ah |
| 00:14.03 | Circuitsoft | Has jlink support been removed from the latest openocd? |
| 00:14.53 | roxfan | i think it's in a state of flux |
| 00:15.39 | roxfan | it was working for some people... not working for others... then someone rewrote the whole thing or something like that |
| 00:17.11 | Circuitsoft | I just don't see it listed after doing ./configure --help |
| 00:17.42 | roxfan | weird |
| 00:18.14 | roxfan | AS_HELP_STRING([--enable-jlink], [Enable building support for the Segger J-Link JTAG Programmer]), |
| 00:20.31 | Circuitsoft | Oh well. I'll wait for my co-worker to arrive with the Olimex probe tomorrow and try it then. |
| 00:20.57 | Circuitsoft | Thanks. |

| 00:39.04 | pthomas__ | hello, I'm new to openocd, I just got a signalyzer JTAG and I will be using it on a new open hardware imx27 board we're developing, but for now it's hooked up do an ilogic dev board. I pulled and compiled the latest SVN, and that worked. openocd started OK. |
| 00:39.58 | pthomas__ | Now I want to load a redboot image to ram, but before that I'd just like to test out the ram. Is the some sort of memory info or memory test with openocd? |
| 00:41.10 | roxfan | there is mdw |
| 00:42.11 | roxfan | ram info is not available using jtag... so you either have to know it from some other means |
| 00:42.18 | pthomas__ | so I guess I need to know where the external ram is mapped to? |
| 00:42.43 | roxfan | yes |
| 00:47.31 | pthomas__ | the manual says it's at 0xA000_0000, and when I look there I get stuff back. |
| 00:48.51 | pthomas__ | in the help fast_load_image says "same args as load_image", but I don't see an entry for load_image? |
| 00:50.15 | roxfan | i think it's load binary |
| 00:50.56 | pthomas__ | I lied, I do see load_image |

| 15:43.04 | dirk2 | yes, was busy with other stuff, haven't got the details yet ;) |
| 15:43.18 | dirk2 | Strontium: What I observed while doing all the stuff manually |
| 15:43.40 | dirk2 | was that dap apsel 1 sometimes fails the first time |
| 15:44.07 | dirk2 | Strontium: Is this what your mail tries to say? Or is this an other issue? Sorry for asking ;) |
| 15:44.31 | Strontium | yes, thats it. With the script it became very clear |
| 15:44.54 | Strontium | its immediately after a target reset |
| 15:45.34 | dirk2 | yes. While doing it manually, I didn't care and just did it a second time |
| 15:45.43 | dirk2 | But a script might fail with this :( |
| 15:45.58 | Strontium | and so it did :) |
| 15:46.29 | Strontium | Its like the results of the work done by ahbap_debugport_init(swjdp); are ignored. |
| 15:46.49 | Strontium | so you need to do it a second time to get them to register |

| 15:47.59 | Strontium | Id love to help out debuggin this, but arm wont give me access to any of their "need their permission" documents, because my company doesn't have a web page. |
| 15:48.21 | Strontium | and by this I mean Cortex-a8. But i will do as much as I can with the public docs |
| 15:48.39 | dirk2 | Strontium: Documents: I thought this first, too. |

| 15:49.18 | Strontium | I am stumped as to how to fix it properly though. I need to learn more about the code |
| 15:49.30 | dirk2 | http://elinux.org/BeagleBoardOpenOCD#Cortex_A8_support |
| 15:49.36 | dirk2 | i.e. the first 2 documents |
| 15:49.46 | dirk2 | you only need *any* mail address |
| 15:50.00 | Strontium | thats them, |
| 15:50.00 | dirk2 | I tried it with my gmail address and it worked |
| 15:50.12 | Strontium | really. I thought it would be the same as the architecture reference |
| 15:50.28 | dirk2 | Strontium: no, there seems to be a difference |
| 15:51.03 | dirk2 | There seems to be really confidential documents where applys what you describe |
| 15:51.29 | dirk2 | Then there are these documents, where you just have to ack a 'license agreement' by giving them your mail address |
| 15:51.31 | Strontium | ok, i will try and get them then. |
| 15:52.34 | dirk2 | As I understand it, the 'license agreement' just tries to ensure that you use the documents for JTAG SW development and not for copying their IP into other SoCs |
| 15:53.52 | Strontium | ok, thanks. will try and dl them now. |
| 15:55.44 | dirk2 | ok, and I will read your mail a little more carefully ;) |
| 15:57.48 | Strontium | sorry if its confusing. |
| 15:58.02 | Strontium | glad I caught you. I was just about to call it a night. |
| 15:58.35 | Strontium | I will be on here most of the time now, so if you need me to do anything for you, just msg me. |
| 16:02.19 | dirk2 | I'm happy that the number of people looking at Cortex A8 support for OpenOCD increase now :) You, Magnus, Ray -> Hopefully we will get it to run now, soon. Unfortunately, I have only some minutes each day for this. So please some patience if I don't answer immediately... |

| 20:43.48 | jeez__ | hey guys, does anyone know where can I find the ARM register context structure in OPenOCD src ? |
| 20:44.14 | Circuitsoft | Do I at least have ft2232_layout right? |
| 20:50.12 | ja2 | jeez__: 'reg' or? |
| 20:50.52 | ja2 | Circuitsoft: Something is fuzzy with your .cfg. I dont know what. |
| 20:51.48 | Circuitsoft | ja2: I actually got the config verbose from the manufacturer of the target. |
| 20:52.03 | Circuitsoft | Did I at least specify the correct ft2232_layout? |
| 20:53.32 | ja2 | That I do not know. Are you linux or win? |
| 20:53.36 | Circuitsoft | linux |
| 20:53.51 | ja2 | If you cat /proc/bus/usb/devices |
| 20:54.08 | ja2 | and look for your jtag devices. |
| 20:54.24 | ja2 | Are they on USB by the way? |
| 20:54.30 | Circuitsoft | yes. |
| 20:54.36 | Circuitsoft | Olimex FT2232-based |
| 20:54.45 | Circuitsoft | S: Product=Olimex OpenOCD JTAG |
| 20:55.02 | ja2 | Me too. To be honesy, I got it working today. Never used ARM before. |
| 20:55.10 | Circuitsoft | I:* If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=usbfs |
| 20:55.29 | ja2 | Ok, so the driver is loaded alright. |
| 20:55.30 | Circuitsoft | I've been using a Segger J-Link on Windows for several months. |
| 20:55.43 | Circuitsoft | Worked quite nicely, but Windows is getting gradually more and more annoying. |
| 20:56.02 | Circuitsoft | And they don't have a GDB server for Linux. |
| 20:56.39 | ja2 | Windows was annoying already at 3.1 |
| 20:57.00 | ja2 | in the .cfg you go: ft2232_layout olimex-jtag ? |
| 20:57.20 | Circuitsoft | yes |
| 20:57.51 | ja2 | and: ft2232_vid_pid ? |
| 20:58.02 | Circuitsoft | Had to set ft2232_vid_pid since it refused to work with ft2232_descriptoin |
| 20:58.17 | Circuitsoft | It's finding devices on the chain, so I think it's communicating properly. |
| 20:59.40 | ja2 | Yes. You got a line with jtag newtap ... ? |
