| 13:16.59 | pytey | bodksi: if you are going to buy that module you may as well just buy this - http://www.amontec.com/jtagkey-tiny.shtml |
| 13:17.36 | bodksi | hi pytey :) |
| 13:17.45 | pytey | hello |
| 13:17.49 | bodksi | yes, I am looking at that one too |
| 13:18.09 | pytey | I like the jtag-key tiny |
| 13:18.34 | bodksi | however, two things: the postage from amontec is nearly as much as the jtagkey-tiny and... |
| 13:19.17 | pytey | are you in EU? |
| 13:19.58 | bodksi | the dpl-usb module uses the new ft2232h (jtagkey[tiny] uses previous (usb 12mbps max) ft2232 chip |
| 13:20.06 | bodksi | yes UK |
| 13:20.44 | pytey | yes, shipping is expensive, and they are shipped from .ch so I had to pay taxes |
| 13:20.57 | pytey | fair point about the ft2232h, didn't notice that |
| 13:22.36 | bodksi | I nearly bought the jtagkey-tiny, I was in negotiation with Lauren Gauch (amontec guy) about postage, but he hasn't responded |
| 13:22.48 | bodksi | I am on a budget |
| 13:22.58 | pytey | where in the UK are you? |
| 13:23.13 | bodksi | currently using a homemade wiggler (parallel port) cable |
| 13:23.21 | bodksi | Chichester, W.Sussex |
| 13:24.12 | bodksi | my wiggler is slow and temperamental :( |
| 13:24.15 | pytey | there is another programmer that is cheap and has various firmware for different functions |
| 13:24.24 | pytey | not sure about openocd support though |
| 13:24.37 | pytey | I think it is supported |
| 13:24.47 | bodksi | usbprog? |
| 13:24.53 | pytey | yeah |
| 13:24.56 | pytey | 15 quid |
| 13:25.05 | bodksi | wow, where from? |
| 13:25.19 | pytey | I've even seen them for 10 |
| 13:25.33 | pytey | from HK |
| 13:25.34 | pytey | http://cgi.ebay.co.uk/NEW-USB-AVR-JTAG-Programmer-Debugger-buffer-chip-/270569147027?cmd=ViewItem&pt=LH_DefaultDomain_3&hash=item3eff2d8a93#ht_2348wt_970 |
| 13:26.15 | bodksi | embedded-projects (run by one of the original designers grad students) are selling it for ~40 euros |
| 13:26.18 | pytey | not sure if that is the one |
| 13:26.21 | pytey | yeah |
| 13:26.32 | pytey | maybe that is just an AVR programmer |
| 13:26.42 | pytey | it looks similar |
| 13:27.10 | pytey | here we go, this is even better - http://cgi.ebay.co.uk/USB-JTAG-Adapter-programmer-cable-ARM-7-9-Cortex-/280497107039?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item414eee305f#ht_552wt_1058 |
| 13:27.20 | bodksi | yes it does, maybe it si a usbprog clone with AVR 'firmware' loaded on board |
| 13:28.45 | pytey | yeah, probably |
| 13:29.39 | pytey | http://cgi.ebay.co.uk/ARM-Emulator-Ulink2-USB-JTAG-Adapter-NEW-Upgrade-/180495313217?cmd=ViewItem&pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item2a065be941#ht_500wt_1073 |
| 13:29.42 | pytey | from .cz |
| 13:29.44 | bodksi | the world of jtag is a quagmire of devices, firmwares and proprietry codes etc. it is so confusing! |
| 13:29.49 | pytey | so no tax |
| 13:31.53 | pytey | olimex are another good supplier |
| 13:32.40 | pytey | http://olimex.com/dev/arm-usb-tiny.html |
| 13:33.05 | bodksi | The reason I'm curious about the dlp-usb1232h is the ft2232h chip. Im not sure on the details but all the new devices that are appearing with adaptive-clocking (RCLK) are based on ft2232h. RCLK allows better stability when device changes clock speed (power management etc) |
| 13:33.49 | bodksi | e.g. jtagkey-2 uses it: http://www.amontec.com/jtagkey2.shtml |
| 13:34.14 | pytey | http://olimex.com/dev/arm-usb-tiny-h.html |
| 13:34.26 | pytey | "High speed USB 2.0 with lower lattency time, RTCK adaptive JTAG clock up to 30Mhz and higher throughput achieve x3-x5 times faster programming speed than ARM-USB-TINY, can be used with all ARM devices for programming and debugging." |
| 13:34.58 | bodksi | or RTCLK rather |
| 13:35.06 | bodksi | yes I hear Olimex are good |
| 13:35.12 | pytey | 39 EUR |
| 13:35.24 | bodksi | thats not bad |
| 13:36.31 | bodksi | hmm, I wonder when it says 2.0-5.0V if that means it cannot do 1.8V targets |
| 13:37.17 | pytey | there is a dude in Ukraine who clones all the olimex stuff |
| 13:37.23 | pytey | it is cheaper |
| 13:37.32 | bodksi | I would like to see inside that Olimex device, I bet adding RTCLK support to it is fairly simple |
| 13:37.44 | bodksi | (and mainly done in software on host) |
| 13:41.05 | bodksi | does the Ukranian guy chat here? |
| 15:32.33 | pytey | bodksi: no, it is a seller, I'll look up his site when I get back |
| 15:33.06 | bodksi | ok thanks a lot, good chatting with you :) |
