| 14:51.59 | GPSFan | prpplague: morning... |
| 14:52.07 | prpplague | GPSFan: greetings |
| 14:52.12 | prpplague | GPSFan: how goes the gspi hacking? |
| 14:52.47 | GPSFan | prpplague: could you tell me if there is a reset (and/or) power-down pin on the 88W8686? |
| 14:53.12 | prpplague | GPSFan: there are both |
| 14:53.31 | prpplague | one sec let me look at a schematic |
| 14:53.49 | GPSFan | prpplague: any chance of a pin # or two?? ;>) |
| 14:54.18 | prpplague | GPSFan: sorry the pinout varies between chip manufacturer |
| 14:54.39 | GPSFan | i think I've found one or the other, and it's associated GPIO. |
| 14:55.01 | prpplague | GPSFan: the 8686 is have is from wi2wi which is licensed producer of marvel 88w8686 |
| 14:55.32 | prpplague | GPSFan: the core is the same, but they generally package it differently with other items |
| 14:55.45 | GPSFan | more than Marvell makes the 88W8686? there are many module manufacturers , but only 2 chip types. bga and sop. |
| 14:56.01 | prpplague | GPSFan: for instance, the wi2wi chip i have has a 88w8686 core and a CSR bluetooth |
| 14:56.13 | prpplague | GPSFan: marvell license out the libertas to other companies |
| 14:56.19 | GPSFan | wi2wi is not a chip, it is a module. |
| 14:56.45 | prpplague | GPSFan: i assure you it is a single chip |
| 14:56.55 | prpplague | GPSFan: they refer to it sometimes as a module, but it is a single bga package |
| 14:56.59 | GPSFan | the z2 has a bare 8686 on it |
| 14:57.05 | prpplague | GPSFan: yea |
| 14:57.11 | GPSFan | mcm |
| 14:57.26 | prpplague | GPSFan: i only have pinouts for the wi2wi which has different packaging/pinouts |
| 14:57.31 | GPSFan | multi-chip module, zcomax has one or 2 |
| 14:57.46 | prpplague | GPSFan: actually i have the pinout s for the 8385 cores from marvell, but not the 8686 |
| 14:58.00 | GPSFan | I've found pinnouts for many modules, |
| 14:58.31 | prpplague | GPSFan: yea we purchase a bunch of the libertas stuff rom zcomax |
| 14:58.40 | prpplague | GPSFan: we use both the xg-180 and the zg-182 |
| 14:58.43 | prpplague | xg-182 |
| 14:59.15 | GPSFan | I accidently ripped up a trace soldering wires onto the clock & CS lines. was able to repair it though. my poor Z2 is getting somewhat beat up. |
| 14:59.22 | prpplague | GPSFan: hehe |
| 14:59.44 | prpplague | GPSFan: anyway, the wi2wi does show that it has a power down and reset that are specific to the 8686 |
| 15:00.21 | prpplague | GPSFan: our design we actually have a mosfet tied to a gpio so we can cut power completely to the radio if needed |
| 15:00.22 | GPSFan | I even found a die photo of the bga package's die |
| 15:01.05 | prpplague | GPSFan: wow thats pretty cool, alot more info on the web for the libertas stuff now days than when i started tinkering with them 2 years ago |
| 15:03.27 | GPSFan | the problem I've been having is that I don't have a good reference for what the machine code needs to be for the SPI kernel framework. I've put in what I think it should be, and the probe function of the libertas_spi.ko is called, but fails while setting the bus_mode. It can't read back what it wrote. All I get back if ffff. so either the chip isn't turned on, it is in reset, or the packet format in the SPI transfer is incorrect. |
| 15:04.26 | GPSFan | prpplague: it doesn't help that the Z2's original gspi driver uses PSP mode not SPI mode. |
| 15:04.58 | GPSFan | but of course that's specific to the PXA270's SSP/SPI controller. |
| 15:05.27 | prpplague | GPSFan: doesn't the pxa270 have a spi core framework in the current kernel? |
| 15:06.21 | prpplague | GPSFan: i could have sworn it already did |
| 15:06.39 | GPSFan | yes, but it is very unclear (to me at least) as to how you set all the proper configurations. I haven't found any good examples of working machine code. |
| 15:07.01 | prpplague | GPSFan: ahh |
| 15:07.20 | prpplague | GPSFan: that was a problem for me at first for the s3c24xx stuff |
| 15:07.31 | GPSFan | the pxa2xx and spi-summary in the kernel doc's are not quite up to date with the code. |
| 15:08.13 | prpplague | GPSFan: don't forget that spi has 4 different timming configurations |
| 15:08.15 | GPSFan | I've looked at the code & doc's in 2.6.28 and they are somewhat better, but of no real help. |
| 15:08.36 | GPSFan | yews, I know and different bits-per-word |
| 15:08.53 | prpplague | GPSFan: are you able to load up the original driver and do a register dump of ssp/spi controller? |
| 15:08.55 | *** join/#edev kergoth (n=kergoth@65.200.49.156) |
| 15:09.34 | kergoth | morning |
| 15:09.39 | GPSFan | I've read out the config reg's for a working unit, and after my driver starts, and they are very different (probably the real problem) but I havn't been able to figure out how to fix it. |
| 15:10.05 | GPSFan | thus the desire for a good example. |
| 15:11.16 | GPSFan | the doc's say that the SPI config can be changed on a packet-by-packet basis, but I don't see how to do that in the machine code. and the driver seems to be using some defaults that are not proper for the 8686, |
| 15:12.30 | GPSFan | prpplague: I've been busy the last few days and have been sort of taking a brake, but mean to start up again today. |
| 15:14.24 | prpplague | GPSFan: ahh |
| 15:14.38 | prpplague | GPSFan: well since i don't have a complete working unit, i can't help |
| 15:14.45 | prpplague | GPSFan: other than look at traces |
| 15:14.51 | prpplague | kergoth: greetings |
| 15:15.01 | GPSFan | prpplague: I also need to poke at the sound driver again, I want to get recording working. |
| 15:15.18 | g1powermac_PB | prpplague: I can send you the remnants of the one I have here |
| 15:15.19 | GPSFan | prpplague: thanks for all your help, it has been useful. |
| 15:15.32 | prpplague | GPSFan: thats what i'm doing today, trying to verify all the hardware/software for our audio on the 8050 |
| 15:15.37 | prpplague | g1powermac_PB: no time |
| 15:15.48 | GPSFan | g1powermac: you could send it to me if it is bricked. I'll wipe off the parts and ring out the trades. |
| 15:15.48 | g1powermac_PB | ahh |
| 15:16.01 | GPSFan | traces |
| 15:16.04 | g1powermac_PB | GPSFan: well, its everything minus the board itself |
| 15:16.05 | prpplague | g1powermac_PB: all my spare time right now is going into learning wince dev |
| 15:16.12 | g1powermac_PB | GPSFan: prpplague has the board |
| 15:16.22 | GPSFan | ah I see. |
| 15:16.40 | prpplague | GPSFan: thats what i've been using to do trace lookups |
| 15:16.42 | g1powermac_PB | prpplague: ahh, good luck |
| 15:16.58 | GPSFan | I sure wish that T0mW had not geven away his bricked unit. |
| 15:17.17 | GPSFan | given even |
| 15:17.22 | prpplague | g1powermac_PB: hehe, thats like me saying, "i'm going to cut my leg off today when i have time" and you responding "ahh, good luck" |
| 15:17.39 | g1powermac_PB | hehe |
| 15:17.54 | g1powermac_PB | it still works, kinda ;-) |
| 15:18.45 | GPSFan | prpplague: might you have any zcomax parts that are dead? |
| 15:19.27 | prpplague | GPSFan: i'll check |
| 15:19.39 | GPSFan | 8686 versions. |
| 15:20.07 | prpplague | GPSFan: i sent most of our spares and dev stuff to dan williams awhile back |
| 15:20.44 | GPSFan | prpplague: I wouldn't want a working unit, just a dead one to trace out the reset & power down pins. |
| 15:21.40 | prpplague | GPSFan: i'll see what i can find, we have a pretty good warranty deal with zcomax, so they usually box them up once a month for as RMAs |
| 15:22.05 | GPSFan | prpplague: ah well it was worth a try. |
| 15:22.18 | prpplague | GPSFan: but i will check |
| 15:22.31 | GPSFan | thanks... |
| 15:24.13 | prpplague | GPSFan: things are a little topsy turvy here, i have to be a little careful right now |
| 15:25.46 | GPSFan | prpplague: understood, don't do anything that might invoke the Terminator. |
| 15:29.54 | g1powermac_PB | hmm, might have been too late. . . |
