| gustav28 | Citronics say they run Linux Alpine, and postmarketOS is Alpine... | 00:01 |
| sad_plan | correct | 00:05 |
| gustav28 | so, maybe Citronics are just using postmarketOS? | 00:05 |
| gustav28 | oh, https://github.com/torvalds/linux/blob/master/arch/arm/boot/dts/qcom/qcom-msm8974pro-fairphone-fp2.dts | 00:05 |
| sad_plan | im somewhat inclined to belive that they actually run alpine, as oposed to PMOS, seeing as its supposed to be a computer, not a phone. even more so if theyve stated they use alpine aswell | 00:08 |
| gustav28 | noob question: is there enough information in the .dts file to make a schematic for a MNT module? it should list the pinout, right? | 00:09 |

| gustav28 | went into the "linux board bringup" rabbit hole on youtube :o | 01:46 |
| gustav28 | I kind of want to try to make a minimal hello world .dts for fairphone 2 to learn how it works | 01:46 |
| gustav28 | a first question: I don't see any exposed pins on the motherboard (https://www.ifixit.com/Teardown/Fairphone+2+Teardown/52523), is it common for uart to show up on the usb port? the .dts for fp2 that is mainlined uses "blsp1_uart2" (https://github.com/torvalds/linux/blob/master/arch/arm/boot/dts/qcom/qcom-msm8974pro-fairphone-fp2.dts#L21) which is | 01:52 |
| gustav28 | defined here (https://github.com/torvalds/linux/blob/master/arch/arm/boot/dts/qcom/qcom-msm8974.dtsi#L527). I guess I need schematics to understand where gpio pin 4 and 5 go? | 01:52 |
| gustav28 | ok, I got the answer from a person working on postmarketOS: https://forum.fairphone.com/t/information-about-the-debug-connector-on-the-fp2/23746 | 02:02 |
| gustav28 | hmm, maybe this isn't so hard after all? | 02:14 |

| josch_noreform | We recently (in context of my charging potentiometer mod) talked about which wire to use and minute helpfully suggested magnet wire (as it will not rip off the pads when an accident happens). Somebody else (sorry I don't have searchable logs on this machine) noted, how the insulation is hard to get rid of for magnet wire. So today I wanted to share | 14:16 |
| josch_noreform | that I learned about another form of "magnet wire": https://en.wikipedia.org/wiki/Wiring_pencil | 14:16 |

| abortretryfail | wiring pencil is a neat idea. | 15:39 |
| gustav28 | newbie question: if the thing I'm trying to boot linux on does not support booting from sd card (fairphone 2), is the correct way to boot into linux using "initramfs" bundled with the kernel? or is this only needed if the boot/device tree does not setup the sd card correctly? I don't see where you specify "boot from sdcard with this identifier" in | 15:54 |
| gustav28 | the dts file. | 15:54 |
| zeha | thats something you tell the bootloader | 15:57 |
| gustav28 | oh, and I'm confusing boot with filesystem here | 15:58 |
| gustav28 | ah ok | 15:58 |
| gustav28 | so on android phones with fastboot it seems like I can flash the boot partition with my own kernel (and .dts file), does the bootloader then say like "the filesystem is here" to the kernel? | 15:59 |
| zeha | no clue about fastboot | 16:00 |

| abortretryfail | fastboot loads android boot images which contain the kernel, the dtb, and the initramfs all in one file. | 16:06 |
| abortretryfail | You might have better luck with the PostmarketOS IRC/Matrix channels for that topic than here. The Reform doesn't boot like a phone. | 16:07 |
| Sario | Also #android | 16:09 |
| abortretryfail | eh, Android modders live in their own little world that has a lot less to do with Linux than anything else. | 16:09 |
| gustav28 | thanks for the pointers | 16:11 |
| gustav28 | I want to learn more about linux by trying to boot it on the fairphone 2, ideally I don't want anything android-specific on there | 16:14 |
| gustav28 | but maybe its not possible to e.g. use u-boot as a bootloader in the same way the existing mnt reform modules do | 16:16 |
| gustav28 | I will ask in postmarketos | 16:16 |
| + wiedi (~wiedi@ip5f58441e.dynamic.kabel-deutschland.de) | 16:28 | |
| abortretryfail | Yeah if anyone has worked out how to use u-boot and mainline "normal" linux on such a device, it's probably the pmOS folks. | 16:29 |

| gustav28 | ok, after asking there I think I have a way forward: keep using whatever is on the phone (fastboot), flash the boot partition with a kernel+minimal.dts+initramfs. since I just want to get into a shell over serial at first, I don't need to boot into the proper filesystem. | 16:52 |
