| 21:25.06 | [g2] | ep1220 ping |
| 21:26.46 | ep1220 | [g2]: hello |
| 21:28.11 | [g2] | hey ep1220 |
| 21:28.24 | [g2] | how goes ? |
| 21:28.28 | [g2] | how |
| 21:28.37 | [g2] | how's that little board of yours ? |
| 21:28.48 | ep1220 | works fine. |
| 21:28.55 | ep1220 | in the meantime i have 3 more |
| 21:29.16 | [g2] | what do they cost ? |
| 21:30.10 | ep1220 | my cost was a few cent below 60EUR (approx 70 USD) |
| 21:30.47 | [g2] | does it run with Linux or just Windows ? |
| 21:31.30 | ep1220 | I do testing, development on windows. |
| 21:32.07 | ep1220 | i do have a lib which implements the Windows API on linux |
| 21:32.15 | ep1220 | using Libusb |
| 21:32.48 | [g2] | this is usb 1.1 right ? |
| 21:32.51 | [g2] | OHCI ? |
| 21:33.19 | ep1220 | You can configure the chip to use usb2.0 or 1.1 |
| 21:33.28 | [g2] | ahh... |
| 21:33.29 | ep1220 | but it is only 1.1 speed in both cases |
| 21:33.50 | [g2] | so it'd be an EHCI running at full-sped but not high-speed |
| 21:33.53 | [g2] | the 12Mbs |
| 21:33.59 | ep1220 | yes. |
| 21:34.16 | ep1220 | there is an EEPROM on the module |
| 21:34.25 | ep1220 | which holds the config data |
| 21:34.37 | ep1220 | so far i can only prog this one from Windows |
| 21:34.57 | ep1220 | i.e the EEPROM |
| 21:35.05 | ep1220 | (but this is a one time action) |
| 21:35.10 | [g2] | nod |
| 21:35.26 | [g2] | well it could be more than 1 time, but it's at least one time |
| 21:35.29 | vmaster | the ftd2xx allows the eeprom to be written from linux, too |
| 21:35.31 | [g2] | :) |
| 21:36.40 | [g2] | hey vmaster |
| 21:37.10 | ep1220 | There is not much difference between the FTDI Module vmaster has used in his thesis and mine |
| 21:37.13 | [g2] | ep1220 so what are your plans for this device ? Are you going to be selling them ? What are you planning to do with the sw ? |
| 21:38.04 | ep1220 | I definitively gonna sell the PCBs |
| 21:38.21 | [g2] | as a FTDI dev kit ? |
| 21:38.44 | ep1220 | I#d say it it is a complete JTAG IF. |
| 21:38.58 | ep1220 | not so much a dev kit |
| 21:39.04 | ep1220 | (hardware wise) |
| 21:39.27 | vmaster | you plug the dlp2232m dev-kit into ep1220's pcb, and get a jtag interface |
| 21:39.37 | ep1220 | it has levelshifters, is designed so it can be safely attached to a running system |
| 21:40.29 | ep1220 | I also plan to sell a few completly assembled module at "parts cost" to people promising to write software |
| 21:40.29 | [g2] | so I could plug it into a running Loft ? |
| 21:40.43 | ep1220 | yes. |
| 21:40.59 | [g2] | and then do some JTAG debugging ? |
| 21:41.05 | ep1220 | yes |
| 21:41.16 | [g2] | except we need JTAG software for that |
| 21:41.24 | ep1220 | yes :-) |
| 21:41.42 | [g2] | is there a 14-pin ARM config ? |
| 21:42.25 | ep1220 | I am working on an adapter set which includes 14pin-ARM,EJTAG,COP,BDM and some DSP interfaces |
| 21:42.47 | [g2] | so it's USB->(ep1220 board + dlp2232m)->Cable-> DUT (Device Under Test) |
| 21:42.49 | ep1220 | Currently i handwired a 14 to 16 pin adapter, for use on the NSLU2 |
| 21:43.17 | ep1220 | if You have a 20 pin ARM header: yes |
| 21:43.46 | ep1220 | else: usb-> JTAGIF -> adapter -> DUT |
| 21:44.02 | ep1220 | sorry: else: usb-> JTAGIF -> cable -> adapter -> DUT |
| 21:44.17 | vmaster | [g2]: what processor is on the loft? |
| 21:44.26 | [g2] | IXP42x |
| 21:46.33 | vmaster | hmm, maybe you could put ft2232 support into jelie |
| 21:49.23 | vmaster | I'm hoping to add xscale support to my debugger, but I hardly find time to finish my arm7/arm9 rewrite... |
