I have a development board with the S905X4 chip, which has a capacity of 2GB RAM and 8GB storage. I connected it via TTL and found that it is running on a system called AOCPU RTOS. How can I boot CE using the TTL command line?
AML uses u-boot, rtos is for bl30, suspend
Using Ctrl+C can interrupt the process and stay in U-Boot.Typing command from aml_autoscript can boot from usb?
Try the following commands from u-boot console:
boot@SDC or boot@USB
boot@sd boot@usb can’t work.
usbboot usb 0:1 kernel.img
error msg : unknown image type
No, these are not aml boot commands.
It’s hard to lead through what needs to be done.
So easiest is to make more research and compare with an existing booting aml device.
Or just flash Android from another vendor, maybe u-boot is than compatible.
There are multiple ways…
can’t work.some info for now
