No, not really. I used bist just to activate fastboot. I could use idme to change bootmode and restart. I found bist useful so far only in activating fastboot and activating file storage mode (fstor) command. With that I was able to charge the device while in uboot. It seems that KT is charging only when in USB mass storage mode - either via fstor (where you cannot do anything else apart from restart) or when framework is booted, usbnet is not active and KT is plugged to the computer.
Code:
uboot > ?
? - alias for 'help'
bist - start Built In Self Test
boot - boot default, i.e., run 'bootcmd'
bootd - boot default, i.e., run 'bootcmd'
bootm - boot application image from memory
go - start application at address 'addr'
help - print online help
idme - idme - Set nv ram variables
log - manipulate logbuffer
printenv- print environment variables
reset - Perform RESET of the CPU
run - run commands in an environment variable
setenv - set environment variables
version - print monitor version
