========================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.
