Re: [ts-7000] Uncompressing Linux Stop

[Mark Featherston <>]

Xiang,

If you check the mailling list history I recently gave a more in depth explanation of some issues with the 2.6.34 kernel, but essentially there are 2 problems. 

1) If you're using FPGA revision 10 the 2.6.34 kernel it turns off support for NAND even though the driver is present.  If you recently ordered a board, or you applied the AVR update this will be the case.  You can use a later vanilla kernel which has this fix (even 3.0+ has support for the TS-7800), or apply the fix I mentioned in the other 2.6.34 post.

2) createmtdboot and createmtdroot will use the MBR that only works with our 2.6.21 kernel.  You need to use mtdcopy and write the corrected MBR which has ATAGS the non-TS kernel will recognize.

There is some more information on the ATAGS here:
http://oz.embeddedarm.com/~mark/index.php/TS-7800#ATAGS

Of course the simplest solution is to use the supported 2.6.21 kernel.  For example, if you use this image you can just run 'createmtdboot && createmtdroot' as you would expect:

Dear all,

I am trying to boot my TS7800 with 2.6.34-512mb-sd.dd released by TS company. I used a dd command (sudo dd if=2.6.34-512mb-sd.dd of=/dev/sdb) to make my own sdcard as the bootable card. And then, use it to boot my board into a fastboot environment. After that, I use the createmtdroot command to write the contents of sdcard to NAND flash. Then, I took off the Jump 1 and plugged out the sdcard, and reboot the board.

When rebooted, the process is stoped at "Uncompressing Linux....done, booting the kernel". Would anybody please point me what step I missed? Thank you so much.

Best Regards,
Xiang Lu
