| 06:18.54 | eFfeM_work | Gaston|Home: nice pics, for hd to cover isolation just use some plastic. In my openrd board I just used to cover of a plastic binder |

| 08:25.05 | Gaston|Home | very nice presentation of hawkboard: https://www.element-14.com/community/docs/DOC-23035/l/tech-first-kit-ti-issplhawk-dsp-arm-dev-kits |
| 08:26.39 | Gaston|Home | eFfeM_work: yes, any plastic would do for electrical isolation, but I'm worried that the whole box will sing when the disk spins. So some type of silicon rubber or similar to mechanically isolate it would be nice. |
| 08:27.36 | eFfeM_work | in that case use some foam, but I am not too sure if that does not obstruct air flow too much |
| 08:29.32 | Gaston|Home | http://www.reichelt.de/?ACTION=3;ARTICLE=97895;PROVID=2402 |
| 08:31.58 | Gaston|Home | Ill try cutting two strips of foam first. |
| 08:33.45 | eFfeM_work | only risk is that the disk can't get rid of its heat well enough, but if instead of encasing it all you use foam strips, i guess you'll be fine |
| 08:33.50 | eFfeM_work | no warranty though |
| 08:33.58 | Gaston|Home | :) |
| 08:34.15 | eFfeM_work | use 4 strips, top, bottom, front, rear |
| 08:34.55 | Gaston|Home | I'll bolt the disk down from below |
| 08:35.22 | Gaston|Home | so I think two strips along the edges will suffuce as a test |
| 08:35.30 | Gaston|Home | suffice |
| 08:36.01 | Gaston|Home | Have you started to code the Minix stuff? |

| 11:42.40 | pazzodalegare | Hi all, I would like to turn off (static power down) the DSP on my hawkboard, do you have any directions? I have a look at OMAP L138 system guide and DSP power down controller: if I understand well I have to put a sw for the dsp which asks for idle, after setting MEGPD |

| 13:07.30 | ventoneicapelli_ | Hi all again. |
| 13:08.41 | ventoneicapelli_ | I'm trying to build newer u-boot (respect to the one from code.google.com/p/hawkboard). I start using OE u-boot but it doesn't work. |
| 13:09.36 | ventoneicapelli_ | Do you found working u-boot src (newer than what is on code.google.com)? |
| 13:12.32 | eFfeM_work | i would expect the oe u-boot to work |
| 13:12.42 | eFfeM_work | you mgiht also want to look at the u-boot git |
| 13:17.52 | ventoneicapelli_ | eFfeM_work: oe u-boot doesn't work. I'm on testing2010 branch |
| 13:18.19 | eFfeM_work | can you tell what does not work? |
| 13:18.52 | ventoneicapelli_ | It doesn't boot, and it seems to reset cyclically |
| 13:19.16 | ventoneicapelli_ | I have no messages on serial console... |
| 13:19.30 | eFfeM_work | hm, wrong start address? |
| 13:19.50 | ventoneicapelli_ | do you have a working u-boot from OE? if so, could you please send it and I would try it... |
| 13:19.56 | eFfeM_work | also it might be required to sign it with ais or whatever the name is |
| 13:20.03 | eFfeM_work | i |
| 13:20.07 | ventoneicapelli_ | yes, I signed it |
| 13:20.21 | eFfeM_work | i'm not sure if I ever build one, it ws the signing that kept me from it |
| 13:20.40 | ventoneicapelli_ | with ais, I used elf file from u-boot OE build |
| 13:21.13 | ventoneicapelli_ | but it's very smaller respect to u-boot from code.google.com/p/hawkboard.... |
| 13:21.36 | ventoneicapelli_ | it's around 140kb the former and more than 400kb the latter.... |
| 13:25.49 | eFfeM_work | can you sign under linux? i seem to recall that this required a windows app |
| 13:26.00 | eFfeM_work | size could also be stripped vs non stripped |
| 13:31.58 | ventoneicapelli_ | I use windows to sign the u-boot from OE |
| 13:34.46 | ventoneicapelli_ | is there a procedure to test u-boot without writing it to NAND (so I have the working one on NAND)? |
| 13:35.09 | ventoneicapelli_ | probably one could you uart mode... |
| 13:35.33 | ventoneicapelli_ | (ehm, "could _use_ uart mode) |
| 14:25.22 | ventoneicapelli_ | Thank you for your help |
| 14:25.26 | *** part/#hawkboard ventoneicapelli_ (~mpapini@94.164.61.18) |
| 14:34.05 | Gaston|Home | ventoneicapelli, you can load the new uboot over tftp and then tell the old uboot that you booted from to start executing from that address with run 0x<address> |
