I have a standard image with
- Bianbu 2.1
- Linux kernel 6.6.63 #2.1.0.2 SMP PREEMPT Fri Jan 24 03:39:48 and
- U-Boot 2022.10spacemit-gaebacc0c-dirty (Jan 24 2025 - 02:25:01 +0000
I try to enter to Uboot shell. I reboot my board but it doesn’t have any timeout and started to load a kernel immediately. It seems that bootdelay set to 0.
I’ve tried to get Uboot settings from Linux but couldn’t. fw_getenv doesn’t work.
Ho I can get to uboot shell?
Or is there only one way for me to build and flash my own uboot for this?
