clever: idk if you care btw, but I did boot the efi firmware over netboot the other night. next up will be booting something more fun from there (maybe burning an http url into the EFI payload in the nix module? might be neat)
<samueldr>
though I guess a full linux system running on 9p would be more trivial that way
<samueldr>
or, more coherently booted?
<samueldr>
at some point I really want to take some time and play with network boots
<colemickens>
any particular angle on it?
<samueldr>
nah, just knowing more
<samueldr>
though every time I think about it I end up thinking that a thin or thick client is always better since it can deal with transient network failure

Hello, does anybody use nixos on Raspberry Pi 4 8GB? I have an issue where the board gets stuck in a reboot loop, but where it eventually manages to boot. I'm new to Nixos so maybe I've screwed something up, but I don't think so... Any help troubleshooting this is greatly appreciated.
<clever>
flip[m]: what power supply are you using?
<flip[m]>
clever: not an official raspberry pi 4 USB C, but it was 3+ Ampere iirc. Can't actually check the rating without unplugging...
<flip[m]>
I built NixOS from some fork with support for RasPi 4 8GB, i'm wondering if that could be the issue?
<flip[m]>
last printed message on the console is "Finished Address configuration of wlan0" and "Starting Networing Setup..." and then it just reboots
<clever>
flip[m]: ive heard that the 8gig ram needs more power, and i can see how the PSU may not be able to keep up
<clever>
flip[m]: is the red led blinking any?
<flip[m]>
during boot? It's stable now that it's running/idling
<clever>
yeah, when its looping
<flip[m]>
let me reboot and check
<flip[m]>
no, the green activity LED is blinking, but the Red LED does not
<flip[m]>
except for maybe a split second as the system resets
<clever>
sounds normal
<clever>
i would try turning on the serial logs, and watch those
<flip[m]>
So i think i'm using the unstable tree, if that could be causing issues
<flip[m]>
Don't think i have any way to get UART attached unfortunately
<flip[m]>
The instructions seems to have been updated to use stable nixos since i built? I'll try rebuilding the installer image and see if it changes things
<flip[m]>
unless there's a prebuilt installer image I can use?

thats what ive got in my logs, for creating a pi4 image

AFAIUI HCE would allow the end-user to control this, and it's just acting as the card
<samueldr>
*and*, at the time of its introduction with Android 4.4, wouldn't have required the payment terminal to care about it not being a card
<WRMilling>
I am guessing then current implementations require the terminal to knwow its an NFC capable phone?
<samueldr>
maybe not that it's an NFC capable phone, but using another protocol than the credit card, as I understand it
<samueldr>
(I could be wrong about that bit, but otherwise it makes no sense how paypass/paywave was possible but google pay not on the same terminal in its early days here)
<samueldr>
hard information on the topic is not trivial to gather :/
