Gumstix writing mmc to nand

README.md

Setting Up Gumstix

Flashing Gumstix

1. Open Applications->Intellistreets->Minicom

2. Connect gumstix to Tobi board.

3. Make sure usb cable is plugged into computer and the green light is on next to the usb cable.

4. Run minicom -D /dev/ttyUSB0

5. Insert programming micro sd card.

6. Power gumstix on.

7. When instructed on mincom press s key to stop bootting.

8. Copy and paste mmc rescan 0; fatload mmc 0 ${loadaddr} flash-all.scr; source ${loadaddr}; setenv bootdelay 1; saveenv; and hit enter. Crtl-Shfit-V for paste in termincal. Or right-click and paste.

Verify output looks like;

8. Remove microsd card.

9. Insert media card that is already formatted to ext3.

10. Enter reset hit enter. Wait a minute or two the gumstix will reboot once during its normal process and you should be left with:

Debian GNU/Linux 6.0 v3node-x ttyO2                                             
                                                                                
v3node-x login:

9. Login using adam:sk582!@

10. Run pidof v3node and verify a number appears like 417.

11. Run df -h and last line will be:

/dev/mmcblk0p1         1924048     35688   1790620   2% /media/card

13. Finished, power off gumstix and remove.

Making media card.md

#Creating media cards

1. Open Applications->Intellistreets->Gparted in main application menu. If instructed login with normal credentials.

2. Switch devices on the top right dropdown box to /dev/sdb or similair. Will be one with ~2GB. You may have to refresh by Ctl-R if you removed and inserted a new card.

3. Click on any partitions and click delete until you are left with a completely unallocated device.

4. Click Partition->New

5. Change File System to ext3 and click Add.

6. Click green checkmark and click Apply.

7. Will complete without errors.

8. Can remove card now.
