16:19 <peterm6881> hey Xogium are you there?

16:22 <Xogium> aye

16:23 <peterm6881> im going to make a vanilla BR image of the licheepi_zero_defconfig, with only gadget serial enabled

16:24 <Xogium> oh boy, that will require you modify the linux kernel config

16:24 <peterm6881> im in make linux-menuconfig

16:24 <Xogium> not to mention I don't have any clue how to launch a getty in busybox

16:24 <peterm6881> it should give me a root / password prompt

16:25 <peterm6881> but what do I neeed to switch on in linux-menuconfig

16:25 <Xogium> yes but you have to launch the getty yourself with a shell script of some kind in busybox

16:25 <Xogium> in systemd you're lucky because all you have to pass on the kernel command line is something like console=ttyGS0,115200

16:25 <Xogium> but in busybox that will not work that way

16:26 <peterm6881> meh, lets see what happens lol

16:26 <Xogium> in busybox everything is launched with a script

16:26 <Xogium> even the login prompt and gettys

16:27 <peterm6881> so, gadget?

16:28 <Xogium> so you'll have to use / to search for a couple options

16:29 <Xogium> CONFIG_USB_GADGET

16:30 <Xogium> CONFIG_USB_G_SERIAL

16:30 <Xogium> check that those 2 are set to y

16:31 <Xogium> if they are not, you can press the number of the option like 1 and it will bring you to that setting, then you just literally press y

16:36 <peterm6881> USB Gadget Support (USB_GADGET [=y])

16:36 <peterm6881> so far so good

16:36 <peterm6881> that was enabled by default, but you knew that

16:37 <peterm6881> iwhat do you suppose an audio gadget is

16:40 <peterm6881> Defined at drivers/usb/gadget/legacy/Kconfig:269

16:40 <peterm6881> legacy...

16:40 <peterm6881> are you sure we need CONFIG_USB_G_SERIAL

16:41 <Xogium> yes that's the serial gadget

16:42 <Xogium> and then once those are both set to y

16:42 <Xogium> you need to set the new option that unlocks to y as well

16:42 <Xogium> CONFIG_U_SERIAL_CONSOLE

16:43 <Xogium> an audio gadget is just that. Usb audio interface

16:47 <Xogium> and then after all of this is set to y and it is saved... Oh boy, the fun part. You need to backup the defconfig so it doesn't get overridden when you will do a make clean, or alternatively not do a make clean. I'm assuming you ran the lichee defconfig step then immediately used linux-menuconfig

16:48 <Xogium> if so you should be okay to build the image, but if you do a make clean you're going to atomize the kernel .config you've just tweaked

16:48 <Xogium> so... don't

16:53 <Xogium> so when you exit that menuconfig, just go with a typical make

16:53 <Xogium> but be warned, I doubt very much that busybox will must magically pick up on the gadget serial, like I told you

16:54 <Xogium> so you might be doing this for nothing unless you want to also learn how busybox works on top of it all and how to launch a getty properly with a tty port and such

16:54 <Xogium> *just

17:47 <peterm6881> im trying it without any options changed

17:48 <peterm6881> using the default kernel for lichee zero, 5.3.5

17:48 <peterm6881> br master

17:49 <peterm6881> since i dont need to log in to check if the issue is there

18:20 <Xogium> no option changed ? But if you don't enable anything in the menuconfig you won't even have serial gadget
