| roh | hm 12 cases done. 8 todo ;) | 00:44 |
|---|---|---|
| adamw_ | lekernel, I added a reset ic to solve boot issue, www.ait-ic.com/uploads//2009-05/31/_1243708373_aocdg.pdf | 05:41 |
| lekernel | on the flash reset? and did it help? | 05:42 |
| adamw_ | this is to let PROGRAM_B suffered from un-known voltage level while the tiny duration comes from ON to OFF. :-) | 05:43 |
| adamw_ | i tested 50 times without un-boot. :-) | 05:43 |
| lekernel | mh, ok, sounds good... maybe try a little more, the problem is really rare sometimes | 05:44 |
| adamw_ | but the flash reset, I am thinking also connect reset ic's output connected directly to RP# of flash to let them work in parallel! | 05:44 |
| lekernel | can't we just use a capacitor instead of this reset ic? | 05:45 |
| adamw_ | NO...cannot. | 05:45 |
| adamw_ | i measured many scope, I can show you later to give a very clear explaination. hehe. :) | 05:45 |
| adamw_ | because we also can not realize how ender user 'fast' cycling. | 05:46 |
| lekernel | yeah, if you use the open drain version of the reset ic, it should work in parallel | 05:46 |
| adamw_ | means capacitor (== constant) this won't meet end user's unexpectedly action (variable.) :-) | 05:47 |
| adamw_ | right... | 05:47 |
| roh | this reset ic shouldnt be expensive.. how much is it? | 05:47 |
| adamw_ | that's why I asked the question on list to know if s/w or some where will pull down RP#. | 05:48 |
| lekernel | yes, the fpga needs to do that | 05:48 |
| adamw_ | so yes, I need to solder manually the output to RP# tomorrow. :-) | 05:49 |
| lekernel | so the main problem was on PROGRAM_B? | 05:50 |
| adamw_ | right, exactly! | 05:50 |
| lekernel | mh, I don't get it | 05:51 |
| adamw_ | its pin3 VDD connected to 3V3, pin2 -> GND and pin1 Vout -> PROGRAM_B; | 05:51 |
| adamw_ | well...no worries. | 05:51 |
| lekernel | so you're delaying the FPGA configuration? | 05:51 |
| adamw_ | yeah...just delay 20us to 're-start' fpga's configuration. | 05:54 |
| adamw_ | roh, US 0.092/each, ;-) | 05:57 |
| adamw_ | I'll upload more waveforms to explain. | 05:58 |
| adamw_ | you can check ug380.pdf page 39 to know more first. :-) | 05:59 |
| antgreen | lekernel: I just hit the approval button and it should get processed | 08:25 |
| antgreen | ( I think it's a manual step by somebody ) | 08:25 |
| mwalle | larsc: were modules supported with theobromas original linux port? (is CONFIG_MODULES defined?) | 08:47 |
| larsc | mwalle: no idea, i've never tried it | 11:19 |
| mwalle | larsc: do you have a running image? could you try the command 'mount -t a a /dir'? /dir has to be existing | 11:37 |
| larsc | 'no such device' | 12:18 |
| lekernel | hi | 15:36 |
| lekernel | antgreen: thanks for the gcc write access | 15:36 |
| Action: kristianpaul is wondering if lekernel became now a gcc matainer (at least for rtems?..) | 16:01 | |
| kristianpaul | mantainer* | 16:01 |
| lekernel | i'll maintain the lm32 port yes | 16:02 |
| lekernel | someone has to do it, right? :) | 16:02 |
| kristianpaul | yes | 16:02 |
| kristianpaul | thanks nice, as my bet now is for rtems,no mather if we get linux later,i just realized real time os are ideal for SDR | 16:03 |
| mwalle | lekernel: cool so i can send you some patches soon :) | 16:45 |
| lekernel | yup, please do | 16:46 |
| Fallenou | wooow lekernel you have commit access :) | 16:58 |
| Fallenou | very nice ! | 16:58 |
| Fallenou | now it's you that will be insulted on the bug tracker :D | 16:58 |
| mwalle | hehe, yeah there are some ICEs :) | 17:03 |
