pieric newbie puts my newbie to shame. I'll have to reasd him again to try to absorb some of it. Two months ago I found some random bits of advice on mass storage mode, but clearly not though to help. Glad he fixed it himself.
Anyway, its been two months since I flogged this particular pi horse, and I am ready to give it another try. October 4th Rich gave me the answer, but I made the mistake of trying to extend my mmcblkp02 partition, and some error got me stuck with a larger partition but a filesytem that didn't expand to fill it. At least, I think that is what the error said / meant.
I have new microSD cards, and I will just start fresh. If anybody knows why I would get that error, let me know, becuase I am about to try the "readme" advice again, on a fresh card with a fresh OS, on a pi zero.
"1) Start fdisk partitioning tool as root:
sudo fdisk -u /dev/mmcblk0
Now list partitions with 'p' command and write down the starting and
ending sectors of the second partition.
2) Delete second partition with 'd' than recreate it with 'n' command.
Use the same starting sector as deleted had and provide end
sectore or size greater than deleted had having enough free space
for Mounted Mode. When finished, exit fdisk with 'w' command. Now
partition size increased but file system size is not yet changed.
3) Reboot piCore. It is necessary to make Kernel aware of changes.
4) After reboot expand file system to the new partition boundaries with
typing the following command as root:
resize2fs /dev/mmcblk0p2
Now you are ready to use the bigger partition."
If I recall correctly, the "resize2fs" command spit an error at me. I will try again tonight, and do as Rich said in his post, to get my USB gadget working and get the modules automatically loaded on each fresh boot. Probably get TC.tcz GUI extension put on there too. And of course, my hobbyhorse of the MSSAID, artifical intelligence folders, for my raspbery pi cluster computer.
