| 18:17.23 | likewise | drath: ping. The cfi.patch works for me (tm). |
| 18:18.53 | drath | hey likewise |
| 18:18.57 | drath | cool, thanks for letting me know |
| 18:19.38 | likewise | drath: well, thanks for helping review the code on this. |
| 18:20.10 | likewise | drath: BTW, any experience on what the fastest USB dongle is? |
| 18:20.32 | likewise | I'm getting 30 kBytes/second with the Amontec/JTAGkey to a IXP420@533MHz. |
| 18:20.45 | likewise | while flashing using workspace |
| 18:46.26 | drath | they're all based on the FT2232, so speeed is the same |
| 18:47.41 | drath | likewise: are you using libftdi? or the binary-only FTD2XX? |
| 18:47.45 | likewise | drath: ok, so only a parallel port (or Ethernet one) can do better |
| 18:47.54 | likewise | drath: binary-only under Cygwin |
| 18:48.22 | drath | likewise: the Amontec JTAG Accelerator configuration is the fastest interface |
| 18:48.33 | likewise | drath: I needed to create a production programming tool without losing our BDI2000. |
| 18:48.51 | likewise | drath: but of course we will now see to use OpenOCD for debugging as well. |
| 18:49.20 | likewise | drath: a next processor is a PowerPC though, so we need the BDI anyway |
| 18:52.05 | drath | i've never had a chance to evaluate xscale performance, because the only xscale hardware i've got has a 200khz low-pass on TCK |
| 18:54.59 | drath | but the transfer should be optimized already |
| 18:55.17 | drath | did you measure download to ram speed? |
| 18:55.36 | likewise | drath: no, flash speed (as reported by openocd when finished, after 16 MB) |
| 18:55.51 | likewise | drath: will try to measure the download to RAM speed tomorrow |
| 18:56.57 | drath | likewise: yeah, would be nice to know where the time is being spent |
| 18:57.18 | likewise | drath: probably in windows :-) |
| 18:57.45 | drath | likewise: running with -d slows down a lot, too - -d -l <logfile> improves speed by outputting to a log file instead of console |
| 18:58.20 | likewise | didn't do any debugging/logging during measurement |
| 18:58.42 | drath | ok |
| 18:59.53 | drath | if RAM download turns out to be a lot faster we could increase the maximum buffer size, to reduce the overhead of halting-resuming |
| 19:02.04 | drath | currently only 32kb are used - if you're flashing images of several mb the target needs to be halted and resumed quite often |
| 19:35.16 | likewise | drath: ok, yes I see. |

| 20:26.22 | fluff | anyone having trouble with jtagkey-tiny and the latest openocd? |
| 20:29.50 | fluff | the interface is proving 3V, but there's nothing happening on any of the lines, such as TCK? |
| 20:31.38 | prpplague | fluff: latest build using the flyswatter board works, so i'd guess its either your hardware or something specific to that board layout in openocd |
| 20:32.32 | prpplague | fluff: got me on /ignore over in #h1940 ? |
| 20:33.37 | fluff | hmm, am i still on that channel? my screen session froze and i've relogged in most places |
| 20:34.59 | prpplague | fluff: yep |
| 20:36.36 | fluff | hmm, i know the jtag connection is good, the parallel port verison works |
| 20:36.58 | fluff | i've pulled the unused nRST to VCCtarget by 4K7 |
| 20:37.04 | fluff | and still the thing does f'all |
| 20:37.14 | prpplague | hmm |
| 20:38.13 | fluff | wonder if it is just too low for it work properly, Vtarget is just under 3V |
| 20:39.04 | prpplague | thats possible, i don't see a schematic available |
| 20:39.20 | prpplague | it does say it supports as low as 2v |
| 20:41.37 | prpplague | fluff: so Vref is set to the correct voltage? |
| 20:42.46 | prpplague | fluff: the tiny is 100% usb powered correct? |
| 20:43.44 | fluff | dunno |
| 20:43.45 | prpplague | fluff: might be pulling too much current |
| 20:43.55 | fluff | my scope is a little inaccurate, Vref is 2.8V |
| 20:44.50 | prpplague | fluff: the board you are working with, i assume you have a seperate power supply for it? and not using the tiny to power the board? |
| 20:49.10 | drath | fluff: the jtagkey-tiny page says Wide target |
| 20:49.10 | drath | voltage range |
| 20:49.11 | drath | 2.8V to 5.0V |
| 20:49.26 | drath | not sure how good it is at the lower end of supported voltages |
| 20:49.57 | prpplague | 2.8 or 2.0 ? |
| 20:50.04 | drath | 2.8 |
| 20:50.16 | prpplague | hmm |
| 20:50.20 | drath | "All JTAG signals are 5V down to 2.8V tolerant" |
| 20:50.21 | prpplague | sparkfun's page says 2.0 |
| 20:50.30 | fluff | grr |
| 20:50.32 | drath | oh, sparkfun has the jtagkey-tiny? |
| 20:50.46 | fluff | for what the schematics say is 3.3V, is only reading 2.8V at the board end |
| 20:50.50 | prpplague | supports ARM targets working in voltage range 2.0 \x{2013} 5.0 V DC |
| 20:51.24 | prpplague | hehe |
| 20:51.28 | prpplague | fluff: join the crowd |
| 20:51.52 | prpplague | fluff: btw, i really need to talk to you about the s3c2410 spi driver as soon as you are available |
| 20:52.17 | fluff | any particular problem? |
| 20:52.17 | drath | prpplague: afaik sparkfun only offers the ARM-USB-TINY - that's from olimex |
| 20:52.30 | drath | prpplague: the jtagkey-tiny is from amontec |
| 20:52.37 | prpplague | drath: ahhh, my mistake |
| 20:52.45 | prpplague | looking at the wrong item then, |
| 20:53.21 | fluff | drath: must get around to submitting my s3c24xx nand support |
| 20:53.49 | drath | fluff: did you use the nand.h interface? |
| 20:54.00 | fluff | think I did |
| 20:54.11 | fluff | i've been ill since writing it which is why it hasn't gotten out yet |
| 20:54.20 | drath | great :) |
| 20:54.40 | drath | well, not the being ill thing, but the nand thing :) |
| 20:55.21 | prpplague | fluff: that would be nice, i'd already started working on the nand support |
| 20:55.28 | prpplague | fluff: hadn't completed it yet though |
| 20:55.37 | fluff | the only bit i couldn't get working was using the comms registers to accelerate |
| 20:55.45 | fluff | but this was baded on r17x |
| 20:55.54 | fluff | whatever the problem may be fixed now |
| 20:55.58 | prpplague | fluff: ahh |
| 20:56.07 | fluff | after the next kernel release i'll push it to the list |
| 20:56.10 | prpplague | fluff: i'd like to have that patch if you post it somewhere |
| 21:00.20 | fluff | hmm, their calcs for their DC-DC show it to be set to 2.82V |
| 21:00.30 | fluff | now to not get angry with client |
| 21:01.11 | fluff | hmm, the old values made 3.1V |
| 21:02.01 | prpplague | doh |
| 21:12.25 | drath | fluff: are you using the OpenOCD on linux or on windows? |

| 22:14.02 | fluff | drath: Linux |
| 22:14.36 | fluff | would have been really useful to have ~5years ago when we first did our 2410 boards |
| 22:15.16 | fluff | right, yes, they acknowledge the bug in DC-DC config |
| 22:15.20 | fluff | new board being sent |
| 22:15.44 | fluff | temp solution will be tommorow get the second bench supply out and connect 3V to the probe |
