Hi there! There is a device Khadas VIM2 and it has a number of problems.
- Once I get into the u-boot settings the device stops loading and colsole gives the following:
kbi trigger [wol|rtc|ir|dcin|key|gpio] w <0|1> - disable/enable boot trigger
kbi trigger [wol|rtc|ir|dcin|key|gpio] r - read mode of a boot trigger
kvim2#kbi trigger dcin w 1
kvim2#kbi trigger wol w 1

This goes on and on and on. If I enter recovery and boot into bootloader from there, there are no such problems. But trigger dcin doesn’t works after all. After firmware upgrades of the device, it turns on, but the trigger also does not work.
