stuck at boot on aarch64 device(Qualcomm sc8280xp)

[nuvole]

TL, DR

The device shows scpi tables, then stucking at

disk: sd0* sd1 sd2
>> OpenBSD/arm64 BOOTAA64 1.18
boot>
cannot open sd0a:/etc/random.seed: No such file or directory
booting sd0a:/bsd: 3023768+1214656+12712936+633232 [269381+91+701664+287051]=0x13edb50
FACP SSDT BGRT CSRT DBG2 GTDT IORT APIC MCFG PPTT SPCR TPM2 MSDM DLUT BGRT FPDT

Any help is welcome, thanks!

Background: Recently, I suffer from reversing those gpio pins and pmic regulators, because my device is a windows based and per-installed instead of android so that I can not get info from something like dtbo. So my linux experience is terrible on the device. Then I discovered OpenBSD unexpectedly, I found that OpenBSD offer an ACPI support(I dived into source slightly, found actually it is a mixed support, it uses devicetree and acpi at the same time) for Qualcomm, like it offers qcgpio and qcpmic, etc. And I found the post of OpenBSD, it mentioned that OpenBSD have supported SC8280xp device since 7.2https://www.openbsd.org/72.html. Then I burned disk img to my drive and tried to boot, but with no luck. And I also built a bsd kernel for my device case, because kernel source add some conditions for another specific sc8280xp device, then I tried to use bsd.gdb this time. nothing special other than the similar console log.

Finally, I decide to add some link, if some kind person would like to dive into this.

The sc8280xp is mentioned in the OpenBSD 7.2 and 7.3 release announcements. I found these mentions in the archives of that mailing list at https://marc.info/?l=openbsd-misc&r=1&w=2

You could ask on the OpenBSD misc mailing list. That list is frequented by developers.
