Wrong temperature reading Orange Pi zero 2

[silajim]

I've tinkering with this board, and trying to boot from spl, but the boot halts after reading the temperature sensors, which does not happen when booting from the sd card.

 

After booting from the sd card I read the sensor that causes the problem 

 

# cat /sys/devices/virtual/thermal/thermal_zone0/temp
51740

 

I found in a forum some kernel patches to mitigate this: https://forum.manjaro.org/t/support-for-orangepi-zero2-h616-ddr3-zero3-and-zero-2w-h618-lpddr4/154679

 

Why does it fail when booting from spl, and not when booting from the sd?

 

Here is the system info:

Can you step back in armbian images until you find a linux version that doesn't show this problem?

Do you have the same uboot installed to spi as you have on the sd?

I could to kernels I suppose, but not full images

No, the sd has  2024.01-armbian-2024.01-S866c-P7079-Ha9af-V2dce-Bda0a-R448a while the spl 2024.07 . I guess I could maybe copy the sd one into the spi? But would it boot the usb? How would I even extract the uboot?

I meant to only change the kernel.

 

I have never modified any of my SPI flash orange pis, because I fear bricking them.

I suspect that is your answer as to why one boots and the other doesn't when using the same kernel

Yeah, I found the original uboot under /usr/lib and also compiled it from the source using armbian build, but it seems it's built without env support. Any ideas on how to enable it? I need to extend the usb init timeout so the external ssd has time to initialize.

 

EDIT: nevermind, setting usb_pgood_delay to 10000 instead of 1000 fixed the issue

EDIT2 : for future reference:

remove sdcard if any, remove 1 jumper lead, rember where it was (it's needed to boot the device into FEL mode) 
connect serial adapter to board, with 115200 baud
connect usb-c to computer (if working in a VM pass the allwinner device to the VM)
go to the latest official build, extract it and under it go to: {extracted_path}/usr/lib/linux-u-boot-current-orangepizero2 or simmilar u-boot path
use: "sudo sunxi-fel -v -p spiflash-write 0 u-boot-sunxi-with-spl.bin" to write u-boot into device
reconnect the previusly removed jumper lead (this allow for the device to boot from it's memory chip also known as SPI) 
restart the device and monitor the serial (tty) output
if it fails to detect the usb ssd, increase the usb_pgood_delay envoiroment variable using the serial console:
	editenv usb_pgood_delay
		-> input a number, bigger than the exsting (ms)
	saveenv

if it boots succefully, remove serial cables and close
