Problem with i.MX6Q_SDB_SD_Demo_Image.exe

Hi,

When I was trying to download Linux to my SABRE board I managed to erase the Android image that was on the SD Card and ended up with a version of Linux that wouldn't boot. So I plugged the card into my card reader and ran i.MX6Q_SDB_SD_Demo_Image.exe To restore Android. When I ran the app, no drives where listed in the drop down box. Obviously I couldn't read the card in windows because of the format, so I formatted it under windows and ran the app again, still no drives where listed. I tried clicking "Create" anyway to see what would happen, and it said "invalid argument was encountered". I can't find any instructions to go with this app so how do I use it to create the Andorid demo image on my SD card?

Thanks

Andrew

I have partially solved this problem:

I'm running this app under Windows 7, and needed to run the app as an administrator.

However when I try and run Android it fails. I have entered the following into uBoot:

U-Boot > setenv bootcmd booti mmc2 [Load the boot.img from SD card]

U-Boot > setenv bootargs console=ttymxc0,115200 init=/init video=mxcfb0 video=mxcfb1:off

video=mxcfb2:off fbmem=10M fb0base=0x27b00000 vmalloc=400M androidboot.console=ttymxc0

[Optional]

U-Boot > saveenv [Save the environments]

The above was taken from page 11 of the Android user guide. However uBoot says booti is an unknown command.

What else is needed to make Android boot successfully?

Hi again,

For the benefit of anyone who may read this I did resolve the problem fully.

I reran i.MX6Q_SDB_SD_Demo_Image.exe but this time when I chose the drive I selected PhysicalDrive1 [F:] rather than removable drive [F:]. When I inserted the SD card into the sabre board Android booted without any problems as when I received the eval board.

The problem is that when you format it for linux, you create a couple of partitions, so when you insert it on windows and try to format it it will format one of the partitions only. So selecting the phisicalDrive was a very good move. Good that you solved it. Otherwise you would have needed to format your SD in a linux host in order to erase the partitions and prepare it for android.
