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
bist offers quite a lot of functionality:
Code:
bist > help
?       - alias for 'help'
autoscr - DEPRECATED - use "source" command instead
base    - print or set address offset
boot    - boot default, i.e., run 'bootcmd'
bootd   - boot default, i.e., run 'bootcmd'
bootm   - boot application image from memory
check   - perform MMC CRC32 check
cmp     - memory compare
coninfo - print console devices and information
cp      - memory copy
crc32   - checksum calculation
diag    - perform board diagnostics
echo    - echo args to console
fail    - fail blink fail pattern on LED
fastboot- Fastboot
fstor   - File Storage
go      - start application at address 'addr'
halt    - halt board
help    - print online help
i2c     - I2C sub-system
idme    - idme    - Set nv ram variables
iminfo  - print header information for application image
itest   - return true/false on integer compare
loadb   - load binary file over serial line (kermit mode)
loads   - load S-Record file over serial line
loady   - load binary file over serial line (ymodem mode)
loop    - infinite loop on address range
loopw   - infinite write loop on address range
md      - memory display
mm      - memory modify (auto-incrementing address)
mmc     - MMC sub system
mmcinfo - mmcinfo <dev num>-- display MMC info
mtest   - simple RAM read/write test
mw      - memory write (fill)
nm      - memory modify (constant address)
ocotp   - OCOTP sub system
panic   - panic halt
pass    - pass blink pass pattern on LED
pmic    - pmic    - PMIC utility commands
printenv- print environment variables
reset   - Perform RESET of the CPU
run     - run commands in an environment variable
setenv  - set environment variables
sleep   - delay execution for some time
source  - run script from memory
sspi    - SPI utility commands
version - print monitor version
Wow! Thanks for this. Now I know it is possible to reflash the kernel/bl from uboot.
