i.Mx8M Mini U-boot Halt at autoboot and continue booting on GPIO interrupt

Hello,

I am working on i.MX8M mini, I wanted to halt the system before the system boots to kernel before autoboot.

It shall boot to the kernel only when it receives GPIO interrupt.

 

1. How I can halt the system at U-boot without any user interface?

2. How I can continue to boot to kernel when it receives an interrupt from Used via GPIO in U-boot?

 

Thanks & Regards,

Kailas K.

Hi Kailas

 

>1. How I can halt the system at U-boot without any user interface?

 

one can look at uboot documentation

https://github.com/u-boot/u-boot/blob/master/doc/README.autoboot

 

2. How I can continue to boot to kernel when it receives an interrupt from Used via GPIO in U-boot?

 

uboot does not use interrupts so seems this is not possible, sorry.

 

Best regards
igor
