| 17:36.17 | prpplague | okie dokie thanks, i'll have a look |
| 17:36.31 | prpplague | do you recall having to add any pullup's pulldowns? |
| 17:37.01 | GPSFan | prpplague, I think that the pullups (91k) I added were important. |
| 17:37.42 | prpplague | GPSFan: yea, something strange though, the pxa270 and pxa310 indicate that the cpu has internal pullups |
| 17:39.44 | GPSFan | prpplague, I just found my z2 jtag work on the other machine, let me review it for a bit. |
| 17:46.27 | prpplague | GPSFan: indeed looking at the differences between the hammer stuff and some of the other stuff, looks like i need to have some pullups on the flyswatter |
| 17:46.55 | prpplague | GPSFan: was there a reason you used the 91K ohm resistors? |
| 17:47.02 | prpplague | GPSFan: looks like 10K's should be fine |
| 17:47.34 | GPSFan | prpplague, yeah, that's what my notes say, was supposed to be ~100k, that's what I had 4 of. |
| 17:47.53 | prpplague | GPSFan: 100k or 10k? |
| 17:48.00 | GPSFan | 10k would probably be ok too. |
| 17:48.02 | prpplague | GPSFan: from what i am seeing 10k should be good |
