========================EXPANDING ZGEMMA H9 FLASH TO MICRO SD CARD=====================

ZGEMMA H9 has a 256 MB Flash, so serious hobbyists need to expand its Flash. There are 2 ways:

1) Flash Expander E2 plugin, to a fast USB 3.0 stick (I wrote in detail about it on this forum and elsewhere) or

2) the following script moving it all from the flash to a fast Micro SD memory card (Zgemma H9 Flodder, as it were... ).

Various Micro SD cards have been tested: class4, class 10 and class A1. In principle, they are all working but not all Micro SD cards will work.

HOW TO CHECK IF A MICRO SD CARD IS OK FOR FLASH EXPANSION WITH ZGEMMA H9
=========================================================================

Insert the Micro SD card into Zgemma H9 and reboot the box. Check the /var/logs/message file, using the PuTTy app. Log in by writing:

root
password - for an image you use (for example "pure2" for PurE2 image [without "" signs]).

Now, copy and paste this telnet command into PuTTy:

cat /var/log/messages | grep mmcblk0:

If you see these messages:

Apr 6 19:28:13 zgemmah9t user.info kernel: mmcblk0: mmc0:59b4 USDU1 7.31 GiB
Apr 6 19:28:13 zgemmah9t user.info kernel: mmcblk0: p1

or

May 20 13:25:49 zgemmah9s user.info kernel: mmcblk0: mmc0:aaaa SC64G 59.5 GiB
May 20 13:25:49 zgemmah9s user.info kernel:  mmcblk0: p1

...then you can proceed..

Download the "H9 SDcard Mover" attached to this message.

Extract the zip file and copy all 3 files to Zgemma H9 /tmp folder, using FileZilla Client app, for instance.

Now, right click on h9_mmc.sh file > File permissions > 755 > OK.

Warning: all data on your Micro SD card will be lost when your start this script!

Start the script by the following 2 telnet commands:

cd /tmp

./h9_mmc.sh

Reboot the box and wait for the script to move everything to Micro SD card.

Your Zgemma H9 just got a boost!

Just remember that there is a small price to pay: your flash is larger but the Zgemma H9 might be a bit slower than if everything is running from H9 flash alone.

=======================================================================

How to go back to a previous state of things (rollback to rootfs, to NAND)?

Simply flash a new image.
