Michael_a380Subjective question: Is the mediocre type user missing out on much when not knowing SSH for n900 ?03:39

DocScrutinizer05even of your "mediocre type user" has no faintest clue about shell04:05

DocScrutinizer05daily backup of phone's data via WLAN to PC by a cronjob running on PC04:06
DocScrutinizer05plus "often" the only really useful way to access phone for rescue&forensics when hildon desktop goes totally south04:08

OksanaaTotally south, as in, reboot doesn't solve the problem?.. Glad I haven't encountered anything like this. For cases where GUI freezes and stops responding, I have rigged Shortcutd to killall hildon-home, hildon-desktop, and hildon-status-menu04:46

DocScrutinizer05hildon-home acting up with a borked desktop widget is not exactly unheard of05:04
OksanaaWell, I do not have widgets. Just lots of shortcuts. Used to have bookmarks, but removed them, just in case they overwhelm hildon-home.05:11

PaliDocScrutinizer05: in N900 RX-51 Full Schemantics v 1.0 are missing gpios: eci0 (61), eci1 (62), eci-sw1 (178)19:34
Palido you have some information how are connected?19:34
DocScrutinizer05err, they are not missing?19:34
Palitvout_en is 4019:36
Paliand eci-sw2 is 18219:36
Palibut there are no gpio 61 or gpio 17819:37
DocScrutinizer05sorry I don't get it19:37
Paliwhere is connected gpio 61?19:38
PaliI do not see it19:38
DocScrutinizer05eci0: N4007 -> ECI0 -> OMAP:U3 GPMC_nBE119:38
DocScrutinizer05eci1: N4008 -> ECI1 -> OMAP:H1 GPMC_nWP19:40
DocScrutinizer05I don't know what's eci_sw119:40
Palieci_sw1 --> #define RX51_ECI_SWITCH_1_GPIO17819:41
Paligpio_request(RX51_ECI_SWITCH_1_GPIO, "ECI switch 1"); gpio_direction_output(RX51_ECI_SWITCH_1_GPIO, 0);19:42
DocScrutinizer05I don't know. In schematics I only could guess that this is ECI5 which is connected to OMAP:V3 McSPI2_CS1 and (possibly incorrectly) labeled "GPIO_182"19:42
Pali#define RX51_ECI_SWITCH_2_GPIO18219:43
Paligpio 182 is eci_sw2, not eci_sw119:43
Paligpio_request(RX51_ECI_SWITCH_2_GPIO, "ECI switch 2"); gpio_direction_output(RX51_ECI_SWITCH_2_GPIO, 1);19:43
DocScrutinizer05I don't know what's eci_sw1 then19:43
DocScrutinizer05no faintest clue19:44
Paliin snd rx51.c is: static void rx51_set_eci_switches(int mode) { mode == 3: /* ECI RX/TX connected to mic/bias line */ gpio_set_value(RX51_ECI_SWITCH_1_GPIO, 1);19:45
DocScrutinizer05haven't seen anything in schematics that might correspond to a third ECI switch apart from TV_EN and what you call eci_sw219:45
DocScrutinizer05sorry I can't analyze schematics from sourcecode19:45
DocScrutinizer05give me a pin19:46
Palithere are two gpio switches in kernel code which looks like set how is mic/bias lines connected19:46
Paliand I was not able to find that eci_sw1 in schemantics...19:46
DocScrutinizer05there is TV_EN and an eci switch with no name19:47
*** norayr has quit IRC19:47
DocScrutinizer05no other but those two switches19:47
Palitv_en is different19:48
DocScrutinizer05in schematics it's not19:48
Paliyes, I do not see it too19:48
Palireason why I'm asking...19:48
*** noch has joined #maemo19:49
Palikernel snd code is setting that gpio and I cannot understand what it is doing...19:49
DocScrutinizer05TVOUT_EN = N4022:A1 1SEL, ECI5 = N4022:A3 2SEL19:50
DocScrutinizer05no other swites in whole audio which might be faintly related to ECI19:50
*** robink_ is now known as robink19:50
DocScrutinizer05ECI "bus" consists of ECI0 ECI1 and ECI5, 2,3,4 are nonexistent19:51
DocScrutinizer05I *guess* there are fuzzy bits in kernel sourcecode comment bits and/or naming of vars19:53
DocScrutinizer05NB there's also only eci0 and eci1 in /sys/19:54
DocScrutinizer05/* ECI RX/TX connected to mic/bias line */  sounds pretty bogus19:55
DocScrutinizer05there's no such thing like "ECI RX/TX" in N90019:56
DocScrutinizer05RX ok maybe, but for sure no TC19:56
PaliDocScrutinizer05: run on n900: grep ECI /sys/kernel/debug/gpio19:57
DocScrutinizer05lemme put it bold: I think the sourcecode is shit19:57
*** xes_ has joined #maemo19:57
Palithere is ECI switch 119:57
DocScrutinizer05so can't you find out which pin number GPIO178 is supposed to be on?19:58
*** xes has quit IRC19:59
DocScrutinizer05I don't know if I can find the right table in those 3 * 3000 manual pages19:59
bencohyou're an EE ... you're supposed to :p20:00
Paligrep -i -E 'tv|eci' /sys/kernel/debug/gpio20:00
DocScrutinizer05bencoh: too little RAM20:00
Palithis shows: tvout_sel, eci0, eci1, ecisw1, ecisw220:00
bencohDocScrutinizer05: in brain or in computer?20:00
bencoh(or both?)20:00
Palitvout_sel, eci0, eci1 and ecisw2 are already identified, just that ecisw1 is unknown...20:01
Palimaybe it was just in some n900 prototype?20:01
Paliand nokia forgot to remove dead code?20:01
DocScrutinizer05GPIO_178 aka mcspi2_clk20:03
DocScrutinizer05aka hsusb2_data720:05
DocScrutinizer05aka ball AA320:06
DocScrutinizer05neither of all that shows up in schematics20:08
PaliGPIO_177 is jack insert detection (HEADPH_IND) and according to that plasma-desktopp17764.png connected to mcspi1_cs320:15
Paliand in rx51 schemantics HEADPH_IND is connected to mcspi1_cs320:15
Paliso seems that plasma-desktopp17764.png is correct for n90020:15
PaliGPIO_178 is connected to mcspi2_clk20:16
DocScrutinizer05yes, checked similar plausibility tests20:16
DocScrutinizer05and I searched schematics for all mcspi and found no mcspi2_clk20:16
DocScrutinizer05I searched for all AA3 and even W7, I searched for hsusb and found no hsusb220:17
DocScrutinizer05so I dare to say the schematics have no GPIO_17820:18
Palimaybe it is missing in rx51 schemantics?20:18
DocScrutinizer05how could I tell?20:18
Palior was it just for n900 prototype?20:19
Paliand later removed?20:19
Paliseems possible for me20:19
DocScrutinizer05there *is* stuff missing in RX51 schem, at very least all about UART3 aka debug serial on testpoints20:19
