| 14:56.44 | ferar | hi, having some errors with gdb again: http://gist.github.com/406384 |
| 14:56.55 | ferar | anyone can give a hint pls |
| 14:58.46 | Weaselweb | ferar: i had a similar problem on my at91. seemingly I can't use a hardware breakpoint and single step afterwards |
| 14:58.53 | Weaselweb | try removing the breakpoint after halting |
| 14:59.08 | ferar | you mean thbreak |
| 14:59.17 | ferar | I was looking into that, thanks |

| 15:10.10 | lilalinux | Aloha |
| 15:10.49 | lilalinux | Is there a driver for Xilinx USB-JTAG 03fd:0008 preferrably on OS X? |
| 15:12.19 | Weaselweb | i guess you should check the xilinx website for os x drivers |
| 15:14.06 | lilalinux | I see |
| 15:14.12 | lilalinux | I thought I need a driver from openocd |
| 15:14.55 | Weaselweb | openocd needs support for this xliinx device, but the device still needs some driver for USB access |
| 15:15.23 | Weaselweb | e.g. my amontec tiny jtag key has severed by usbserial on linux, but openocd still needs support for the tinykey itself |
| 15:15.37 | lilalinux | currently I'm using windows in a vmware to develop, but i hoped I could use openocd on os x to debug |
| 15:16.18 | lilalinux | As Xilinx doesn't support anything except Linux and Windows, I guess they don't have OS X drivers just for the jtag |
| 15:18.03 | lilalinux | are there openocd binaries for windows? |
| 15:18.20 | lilalinux | does it need cygwin etc.? |
| 15:19.08 | Weaselweb | i dont use openocd on windows, but afaik there are binaries used without cygwin |
| 15:28.23 | KotH | lilalinux: http://www.freddiechopin.info/ |
| 15:41.40 | lilalinux | thx |
| 15:48.27 | lilalinux | KotH: I installed it, but can't find the executable |
| 15:49.00 | lilalinux | ah, got it |
| 15:50.08 | KotH | it installs some unixish tools too |
| 15:50.26 | KotH | think of openocd on windows as if you'd run it on linux |
| 15:50.32 | lilalinux | hm, why does it try to open network connections? |
| 15:50.39 | KotH | it's not a typical windows app and doesnt behave like one |
| 15:50.45 | KotH | because openocd does |
| 15:50.45 | lilalinux | k |
| 15:50.52 | KotH | read the docs on the control ports |
| 15:50.58 | lilalinux | ok |
| 15:59.54 | ali_as | lilalinux, JTAG to program or do other things? |
| 16:00.35 | ali_as | They used to have open source programming tools. |

| 16:04.20 | lilalinux | ali_as: programming works just fine with ise |
| 16:04.32 | lilalinux | I wanted to do some more stuff with jtag |
| 16:04.36 | lilalinux | just experimenting |
| 16:05.03 | lilalinux | however, I don't want to flash my precious Xilinx USB-JTAG cable |
| 16:05.58 | lilalinux | as suggested here: http://www.ixo.de/info/usb_jtag/#xilinx |
| 16:13.04 | KotH | uhm.. |
| 16:13.29 | KotH | openocds purpose is mostly in programming and debugging CPUs |
| 16:13.44 | KotH | dunno how well it works for FPGA stuff, but i dont think it's that good |
| 16:14.16 | KotH | and if you dont want to fry your xilinx cable, get an amontec jtag-key tiny |
| 16:14.36 | KotH | it's cheap, and oss xilinx tools support it |
| 16:20.50 | wookey | jtag-key tiny is made by olimex |
| 16:21.22 | wookey | amontec do jtagkey and jtagkey2 |
| 16:22.16 | wookey | Olimex is cheapest. Amontec slightly fancier. Both work, but produce different bugs/issues IME |
| 16:22.54 | wookey | openOCD works OK on CPLD/FPGA programming but there are almost no existing configs - you have to work it out |
| 16:38.31 | ali_as | Did openocd give up on supporting non ARM CPUs? |
| 16:42.30 | ferar | hi, I'm having this problem of debugging a simple test program that toggles the scroll-lock on a s3c2450 based board. http://gist.github.com/406510 |
| 16:43.20 | ferar | where this: 0x8064 <_clear_gpa7>:pop{r0, pc} came from gnu-as added it or something? |
| 16:47.54 | ali_as | It looks like the start of your program is somewhere else. |
| 16:48.26 | ali_as | I usually place a software breakpoint as the first instruction in my test program. |
| 16:48.51 | ali_as | That way whereever the linker puts my code I'm instantly at the start. |
| 16:49.01 | ferar | I did place a hb at _start, and it did stop there |
| 16:49.05 | ali_as | Not sure how this is done on ARM though, it's been a while. |
| 16:49.35 | ali_as | I mean a physical instruction. On x86 this would be int3. |
| 16:49.39 | ferar | then as I "si" and get to 0x8064 <_clear_gpa7>: |
| 16:50.02 | ali_as | If pc is being poped then the execution is going somewhere else. |
| 16:50.08 | ferar | the pc changes (there is this pop thing!) |
| 16:50.12 | ali_as | Yes. |
| 16:50.54 | ferar | well, someone tell from where the hec this pop came! nothing like that in the original code |
| 16:51.57 | ali_as | It's a normal way to jump to other code. |
| 16:52.06 | ali_as | Can you single step to see where it goes? |
| 16:52.07 | ferar | humm |
| 16:52.36 | ferar | yep I'm "si" all the time and goes to garbage, |
| 16:52.56 | ferar | for I reset halt and nothing is loaded |
| 16:52.58 | ali_as | Also, not sure I'd use _start. |
| 16:53.37 | ali_as | Try putting your executable into a dissasembler. |
| 16:53.56 | ali_as | Check the labels, see where the code is... |
| 16:53.59 | ferar | ok let me check that quickly |
| 16:54.27 | ali_as | bb an hour or so. |
| 16:58.27 | ferar | here is the disassembley output http://gist.github.com/406536 |
| 16:58.36 | ferar | all seems fine! |
| 17:46.13 | ali_as | What does your memory map look like? |
| 18:02.29 | ferar | ali_as: http://gist.github.com/406618 |
| 18:03.58 | ali_as | Not what I mean, where is the flash, where is the ram, is address translation involved? |
| 18:05.29 | ferar | no MMU is off |
| 18:06.03 | ferar | MMU: disabled, D-Cache: disabled, I-Cache: enabled |
| 18:06.18 | ali_as | Ok, s3c2450? |
| 18:06.22 | ferar | yep |
| 18:09.53 | ali_as | Is this some sort of gps or satnav? |
| 18:10.46 | ferar | no, it is a simple handheld like |
| 18:10.55 | ferar | with gprs |
| 18:11.29 | ferar | you meant memory map (samsung documentation) |
| 18:11.49 | ali_as | Yes. |
| 18:12.14 | ferar | where I can past pic? |
| 18:12.20 | ferar | on the web |
| 18:13.20 | ferar | found it just a sec |
| 18:15.49 | ferar | http://picpaste.com/memmap.jpeg |
| 18:16.53 | ferar | ali_as: http://picpaste.com/pics/memmap.1274293012.jpeg |
| 18:18.13 | ali_as | Ok, how is elf being loaded, that seemsto be a rom area. |
| 18:18.26 | ferar | what is troubling me, is that the original code is not the same as what gdb is loading! I used arm-linux-as / arm-linux-ld to get the binary |
| 18:19.31 | ferar | well first launch gdb as: gdb arm_test.elf |
| 18:19.33 | ali_as | Yes. Either your code is somewhere else or you ae trying to load it into rom. |
| 18:19.57 | ferar | then : load |
| 18:20.42 | ferar | and I get: http://gist.github.com/406637 |
| 18:21.00 | ali_as | Can you use assemble the code for the ram area? |
| 18:22.26 | ferar | you mean 0x3800_0000 |
| 18:22.36 | ferar | starting from there? |
| 18:24.00 | ali_as | Yes or sram at 0x4. |
| 18:24.23 | ali_as | Might be the ORG diective in the assembler. |
| 18:24.43 | ferar | ali_as: but in my openocd I have the following configuration: $_TARGETNAME configure -work-area-virt 0x40002000 -work-area-phys 0x40002000 -work-area-size 0xc000 -work-area-backup 0 |
| 18:25.25 | ali_as | My understanding is the elf contains the address it expects to load to. |
| 18:27.23 | ferar | well, I'm not setting any address that's for sure |
| 18:27.37 | ali_as | That may well be why it's defaulting to 0. |
| 18:28.38 | ferar | fine, how can I set that? |
| 18:29.04 | ali_as | The directive I'm familier with is ORG. Might be .ORG 0xblah. |
| 18:29.23 | ali_as | I've not done ARM assembler in a few years. |
| 18:31.04 | ferar | many thanks |
