I have VIM2 v1.2 with 3GB RAM and 64GB eMMC.
When I’m trying to run any KBI-related command in U-Boot CLI I get “Error reading the chip: -110” error.
Also, some OS images (like VIM2_Ubuntu-minimal-focal_Linux-4.9_arm64_EMMC_V0.9.6-201117) with U-Boot 2015.01 installed using krescue leads to very slow U-Boot startup with following errors (part of boot log):
Product checking: pass! Hardware version: VIM2.V12
[aml_i2c_xfer] error ret = -110 i2c master a current slave addr is 0x18
i2c_read: i2c transfer failed
Error reading the chip: -110
I’m think this may be related to above errors returned by kbi-related commands.
Some other images (like VIM2_Debian-server-buster_Linux-5.9-rc2_arm64_SD-USB_V0.9.3-200907) with U-Boot 2020.04 does not have such slow U-Boot boot problem.
Is something wrong with my VIM2.V12 board, or KBI just does not exist on this board?
