 |
|
Hello folks,
I have been trying to get this thing to boot since a week now, but I don't really know what else to try. I want to mention that I am not completely new to crossdev and cross building gentoo and alpine for embedded devices, in fact I did successfully build a gentoo image for the Raspberry Pi 3b back in 2018 when it came out.
The resources I used to follow are the followings:
crossdev setup
qemu + binfmt setup
Pi 4 64bit install
Pi 3 64 bit install (cross references)
The only thing I have done differently is I did not install sys-boot/raspberrypi-firmware as mentioned in the Pi 4 64 bit install since I think it is pretty pointless given that I compiled the .dtb's, and just copied over the .dat and .elf files from https://github.com/raspberrypi/firmware.

I have the same exact result using sakaki kernel binary and with alpinelinux. I honestly don't know what I am doing wrong. I am happy to upload the image if you want to give it a spin.
Thanks

Latrina,

������� |
That looks like the serial console. The on screen console is probably working as expected.
Gentoo doesn't call the serial port serial0.
Its /dev/ttyAMA0, which normally drives the bluetooth.
That also requires | /etc/inittab: | # Architecture specific features
#f0:12345:respawn:/sbin/agetty 115200 ttyAMA0 vt100 |
at the bottom of /etc/inittab to be uncommented too or you loose the serial console when inittab is processed.
It gets worse ... :)
The serial port baud rate is tied to the ARM CPU core clock, which the kernel and Pi firmware can both change.
You needin config.txt to stop that or the console turns to gibberish or blank, per the last line of your console output.
If you want to put the console on the mini UART, its all different.

Hey NeddySeagoon,
I tried changing console=serial0 with console=ttyAMA0 and console=/dev/ttyAMA0 but I lose serial as soon as the kernel is booted. The entry related to the serial in /etc/inittab has also been enabled.
Also, I am not sure what you mean with "If you want to put the console on the mini UART, its all different.".
I just need to connect to the PI via serial adapter. Nothing fancy I guess. Also, dhcpcd is installed and enabled into my gentoo build, yet it acquires no DHCP from the router. Which is why I was assuming the system was not booting correctly. Unfortunately I don't have a hdmi adapter for this thing to see whats going on, assuming that the issue is the serial connection.
Thanks

I am really starting to get confused. Again, all I need to do is to connect to the rpi from my laptop via ft232r usb serial adapter.

Issue seems to be with agetty. To confirm diagnosis, you can try booting directly into the shell, without a getty: add 'init=/bin/sh' to kernel command-line in cmdline.txt.
EDIT: And, then, you can boot with the normal init, but without the agetty: if I remember correctly, you should be able to replace the /sbin/agetty command and its arguments in inittab with a simple /bin/sh.
If these tests boot you into the shell successfully, then check whether /sbin/agetty is there, is executable, try running it, etc. |

Hey redfish.
Even by adding init=/bin/sh into the cmdline.txt I still lose the serial connection upon the prompt comes up.
| Code: | sh: cannot set terminal process group (-1): Inappropriate ioctl for device
sh: no job control in this shell
sh-5.0# |
Mysteriously it only worked once. I am getting sick at this...

The above output looks correct for init=/bin/sh. This mode says not to launch the normal init process (systemd) and instead just launch a shell, so that's the output we expect. Does the shell work ok -- you can run commands?
The init=/bin/sh is just a first test, that confirms that everything about the serial port works correctly.
Next test is remove 'init=/bin/sh' so that normal init process is launched, but change /etc/inittab to not launch agetty:
| Code: |
s0:12345:respawn:/bin/sh
|
If this also gets you booted into a shell, then you will know that the problem is with the agetty itself, which may be have something to do with it setting options on the tty and breaking it somehow. But, I before jumping to a wrong diagnosis, I would do these tests to confirm whether agetty is the culprit or not. |

No I cannot run any command. The boot process halts there and I cannot type anything into the serial console.
