from Latest Software Images - BeagleBoard this site...how to check GRUB
boot loader take so much time ?? and where we check which software
installed on my system ?
To my knowledge, Beagle Debian releases do not use GRUB -- just u-Boot
any procedure to check which software get so much time take loading on
system ...
Before or after transition to Linux?
[before and after] Connect a USB-Serial adapter to the debug header,
and use a time-stamping terminal program to capture the output of the boot
loaders.
[after] Examine the output of "dmesg"
I show a 6-second delay in mounting the filesystem (SD card, I think this
is the IoT image as it only used a third of an 8GB card)
