Enter maskrom for emmc flashing, from software instead of button?

#1

Hi. I have Rock Pi S0 boards that I install in an enclosure.
It works, but it is conceivable that some critical bug or change with the image is discovered so that customers later need to flash a new image to the emmc. But for them to do this, they would have to open the enclosure and locate the maskrom button, very inconvenient.
Is there a way to trigger rebooting into maskrom from software instead of pushing the button?
Some register on the RK3308 that I can write to or something?

You can run

reboot loader

Command to go to maskrom mode

Thanks for the reply, however I am using Armbian OS, “reboot loader” doesn’t work, it just reboots normally. Sorry I should have specified. What does the reboot loader command do so I can try to replicate it on Armbian? Is there source code? Or can I download and install it directly from somewhere?
