| 02:53.22 | eieioins | i have a project that involves a spansion flash chip and jtag via xilinx. id appreciate someone wiser just giving me an ear... |
| 02:55.24 | eieioins | i could not find much in the form of cheap (<$1k) programmers for the flash. JTAG is somewhat frustrating because openocd does not support xilinx spartan 3s. i have considered adding this support but before that, i would like to explore other routes |
| 02:56.08 | eieioins | one route being using the xilinx tools to create a xsvf to then be played using the Amontec JTAG Key device svf player |
| 02:56.25 | eieioins | the next being digging my ditch with urtag |
| 02:57.20 | eieioins | another option, i am curious if anyone has explored is: the flash chip is CFI compatible. Would it be possible to build a CFI controller with some off the shelf consumer hardware (with modifications, i assume)? |
| 02:58.27 | eieioins | Another route i have considered is bit-banging the interface. after reading the data sheet it does not seem overly complicated |
| 02:59.00 | eieioins | Or, should I go back to openocd and urjtag, looking at bsdl definition files and trying to add support in one of these programs in order to deal with the flash via them? |
| 02:59.30 | eieioins | as you can see as one considers all the possible routes, it is easy to get into a deadlock where you cant figure out which one to take |
| 03:01.27 | flyback | I can't help you but feel free to idle here and also try #electronics |
| 03:01.35 | flyback | actually strogg might help you |
| 03:01.37 | flyback | he does fpga's |
| 03:01.42 | flyback | even though he's a STUPID CANUCK |
| 03:01.46 | flyback | STUPID CANUCK |
| 03:01.50 | flyback | smacks himself |
| 03:01.52 | flyback | thx I needed that me |
| 03:02.08 | eieioins | will check both, thanks |
| 03:02.30 | eieioins | but, well jtag is currently where I am focusing my efforts |
| 03:04.19 | flyback | yeah I trying to learn a little jtag too |
| 03:04.23 | flyback | to hack up old consumer stuff |
| 03:08.55 | eieioins | its definitely an important and fun place to look but sometimes it is frustrating when you need something fast and the tools out there dont support your target and sourcing the specific tools for it are both expensive or take too long :( |
| 03:15.47 | eieioins | anyone know of good hardware reversing channels |
| 03:17.50 | eieioins | i had this idea today, and spoke to flylogic, bunnie and a few others in the know... its very simple. software that uses the fiducial marks on pcbs *(they help align pcb planes in auto placement smt machines) to perfectly align the top and bottom photo of a board with transparncy to help you follow lines that are exposed and through holed |
| 03:19.05 | eieioins | i mean, i just assumed something as simple as this would exist already (basically taking three commone points in the images and exapanding, rotating or doing what has to be done to match the alignment between the images) |
| 03:19.40 | eieioins | okay, everyone is sleeping |
| 03:19.44 | eieioins | guess i should be working |
| 03:27.39 | flyback | http://www.youtube.com/watch?v=_LhneJ2u8WQ&feature=related# |
| 03:29.00 | eieioins | thats pretty cool |
| 03:29.11 | flyback | heh that's like 14 platters |
| 03:29.13 | flyback | 28 heads |
| 03:29.15 | eieioins | i wonder if old hd motors can be removed and reused for other personal projects |
| 03:29.19 | flyback | recovery companies are like "FUCK THAT" |
| 03:29.20 | flyback | they can |
| 03:29.25 | flyback | but they are 3 phase brushless |
| 03:29.29 | flyback | so you need a driver ic |
| 03:29.35 | flyback | it also has to do back-emf sensing |
| 03:29.41 | flyback | so you either need a fast mcu, a dsp or a chip |
| 03:29.49 | flyback | they make ok gens too |
| 03:30.23 | eieioins | sounds like a nice instructable waiting to happen, well, without the dsp... i mean, can an arduino do it? |
| 03:30.39 | eieioins | (atmega168 at 16mhz i think) |
| 03:30.50 | eieioins | (with lots of software bloated overhead) |
| 03:31.05 | flyback | I think |
| 03:31.10 | flyback | but it's going to have to do signal processing |
| 03:31.12 | flyback | of the back-emf |
| 03:31.21 | flyback | and will need I think 3 or 6 pwm outputs |
| 03:31.38 | flyback | i've seen people use pics even |
| 03:31.41 | flyback | depens how fast etc you need |
