Failure to flash OS image to Cardhu dev kit.

Hi,

I am new to Cardhu dev kit and I have been scratching my head on flashing the JB image. I tried flashing on 32-bit Ubuntu first and failed. Then I found the guide document and followed exactly the description on Windows. I’ve been able to install the recovery driver and place the kit in forced recovery mode. I received the identical error message on Linux when I ran flashos.bat file.

Here is the command window output:

Thanks for the bug report - we’ll look into this and get back to you.

BTW, mine is a Tegra3 developer tablet, S/N: 0413012010048. On Windows XP 32-bit, I downloaded and installed tegra-devpack-2.0-windows-2012-10-22-14091158.exe and tegra-osinstaller-cardhu-jb-1.0-windows-2012-10-20-11617556.exe.

The tablet arrived with JB and Fastboot pre-installed, I think.

Hi, yyuan

“sdram config strap: 1” could indicate some board issue of NAND. Can you contact people where you get the devkit from for reparing or supporting?

Also, some board’s USB is sensitive to cable. Remove any extension cable and shorten you USB connection.

Thanks Xuan,

I only used the shipped cable. I also tried a 3ft cable without success.

Hi yyuan,

Was your JB flashing success? Could you please let me know the steps you followed?

HI,

I am also facing same issue.
Please can some body help us here ?

Thanks
