| 09:34.07 | flopflip_ | one generell question, is it possible to use openocd to flash AVRs? (I do have an openocd-usb adapter from embedded projects laying around, but am clueless) |

| 13:56.35 | roxfan | afaik avrs use SPI, not JTAG |
| 14:22.33 | steve|m | the smaller avrs only support SPI-like ISP, the larger ones (>= ATmega16) support ISP and JTAG |
| 14:22.55 | steve|m | urjtag has AVR JTAG support afaik |
| 14:25.16 | steve|m | but avrdude also has support for an "avrftdi" ISP programmer, which should be quite easy to modify for your ftdi jtag adapter |
| 14:29.09 | flopflip_ | okie thx |
| 14:29.51 | flopflip_ | can you point me to some documentation that is easy to understand for non electronic firm ppl? |
| 14:31.06 | steve|m | regarding what? ISP? |
| 14:32.45 | flopflip_ | to get a good overview how to use jtag and stuff |
| 14:32.52 | flopflip_ | and ISP :) |
| 14:34.25 | flopflip_ | basicly we are bunch of computer science students with alot of ppl like: "it has usb, so why is it not programmable via usb?" questions :/ |
| 14:35.44 | steve|m | hm, I don't remember a hitchkickers guide to JTAG, but there are USB bootloaders out there.. but the initial flashing of the bootloader needs to be done via ISP/JTAG |
| 14:35.58 | steve|m | which atmega do you have? |
| 14:36.08 | flopflip_ | rzraven kit |
| 14:36.43 | flopflip_ | basicly there are several good tutorials, all assumeing being familiar with our jtag |
| 14:37.30 | flopflip_ | *your |
| 14:38.35 | steve|m | I have an atmel AVR dragon ISP/JTAG programmer which is supported by avrdude |
| 14:38.44 | steve|m | I never really used it for debugging, just for flashing |
| 14:39.01 | flopflip_ | yeah, that is what we need (basicl) |
| 14:39.08 | flopflip_ | y key sticking :/ |
| 14:39.42 | flopflip_ | we are getting hardware from different ppl (donations) and need to get along with it |
| 14:40.19 | flopflip_ | our focus is on the 802.15.4 stuff |
| 14:40.40 | flopflip_ | so, just getting it on the chip is what we need, and am kinda blind to find good ways |
| 14:42.00 | steve|m | if the raven also has a ISP header, you could use any random isp programmer |
| 14:42.27 | flopflip_ | okie, do you recommend usbprog? as it looks like a good choice for me |
| 14:43.12 | flopflip_ | but as i said, i am fairly new to the topic |
| 14:44.36 | flopflip_ | http://www.embedded-projects.net/index.php?page_id=165 it is, i only have the openocd-usb here, but have no idea whether it works for avr |
| 15:05.07 | steve|m | sounds good, that one should be supported by avrdude |
| 15:05.19 | steve|m | http://www.embedded-projects.net/index.php?page_id=178 |

| 15:08.52 | flopflip_ | thx alot :) |
