espressowifi : wifi card disappeared after disabled wifi (xfce)

By Raymond Hackley on 2024-03-17T06:36:53

added category::ui device-category::community device-samsung-espresso10 ui-xfce4 labels

maybe check via dmesg to see what happens when the card is disabled the first time, and when attempting to re-enable it

Ok, found (from the first log): [ 1.145294] mmc4: Failed to initialize a non-removable card

By cristian_ci on 2024-03-25T14:54:48

@cristian_ci "mmc" doesnt means memorycard? would be "wlan" or "wireless"?

By lm2lm2 on 2024-03-25T18:51:32

it is very well, as it looks like a bit "random" : for two weeks the wifi card was totally absent from linux ; two days ago as i power it on like almost everyday, i see the wifi connected. Today, i see wifi card still disappeared

im wondering if it's not related to the fact i switch off the device to access twrp (and it's very unconvenient to go on twrp on that device as you can't enter it with the cable plugged in), to charge it without big cu consumption ; then rebooted to postmarket and wifi worked back, one time.

i power it off/on everyday. twrp for charging.

Well the wifi card is actually connected via mmc since it is a sdio card for espresso hence it shows up as mmc4 in the logs. We faced similar issue and had a patch for it #1211 (closed) and !3130 (merged) are some related issues.

Could you confirm that wifi stops working only on cold boots and works fine when rebooted from twrp to pmOS?

By Mighty on 2024-04-09T09:56:08

yes and no

it's very very hard to get "the system you want", as postmarket//twrp//downloadmode with that device

sometimes i have to salvagely reboot the device up to 10 times because it loads postmarket, even if i push voldown or volup from it's powered off until i push power-on button. and with the USB unplugged of course, USB plugged = twrp/download modes will never be launched, always directly the OS.

so after 4 salvage reboots of postmarket with unplugged usb and vol button, i went up to go to twrp. just reboot > system.

device reboots, then, that time, wifi works. i cannot ensure that this sort of bug will not appear again :(

if it disappear again, i think i will repeat the process, and maybe do a dalkvit/cache wipe with twrp, to see.

@MightyM17 found a solution for this, which picks a patch from Robert Nelson and Hansem Ro. In fact, Hansem owns another device with similar specifications: https://raw.githubusercontent.com/hansemro/kc1-linux/v5.16.x/patches/0006-Add-clk32kg-to-twl6030.patch

what is the solution? :D

By lm2lm2 on 2024-04-09T13:46:38

The patch was already added to pmos hence i wanted to confirm whether its the same bug or something else has broken for you for the wifi card to not initialize, since booting from twrp sets those regs for wifi card to start it should work 100% when booting from twrp. But when cold booting before the patch was applied those regs were not set (as downstream modelled a regulator as a clock and that seemed to just work tm for them, we cant use such hacks in mainline) we faced the wifi issue.

By Mighty on 2024-04-09T14:19:27

i can provide logs or do some manipulation if needed. just dont understand why wlan card works only for first startup (or second one), but never after..

By lm2lm2 on 2024-03-22T00:46:03

try to follow the same road as used by embt2ws in mainline kernel.

 wl12xx_pwrseq: wl12xx-pwrseq {
                compatible = "mmc-pwrseq-simple";
                clocks = <&twl 1>; /* clk32kaudio, <&twl 0> would be clk32kg */
                clock-names = "ext_clock";
 };

that needs:

 twl: pmic@48 {
                compatible = "ti,twl6032";
                reg = <0x48>;
                #clock-cells = <1>; /* important for registering clocks. */

okay, ty for your answer, but...

im only a postmarket/linux tester/sysadmin, i never compile kernel..

how should i apply this process?

thank you vm!

By lm2lm2 on 2024-05-23T09:42:33

if that does not help (probably only solves detection problems), maybe blacklist some omap/arm-specific aes crypto module

By Andreas Kemnade on 2024-05-23T09:42:51

you will have to accompany me for this kind of manipualtion :)

By lm2lm2 on 2024-05-23T09:42:51

mentioned in merge request !5216 (merged)

hi @MightyM17 @ollieparanoid , does it means that just wait few weeks to get it fixed in the 6.9.3 pmos kernel?

By lm2lm2 on 2024-06-11T10:48:46

6.9.3 is already available. just upgrade your system

By Sicelo on 2024-06-11T11:06:32

im in stable, means 6.6.3 ; i guess i might upgrade to edge?

or how long is needed to see 6.9.3 on stable?

ty

By lm2lm2 on 2024-06-11T11:06:32

It is available in edge already and will come with the 24.06 release for stable!
