Dear All,

I am now porting U-Boot to Atheros A531x board. Now It can boot it self from flash. I burned Linux image in bfc40000 I use bootm bfc40000 , following things happen ----------------------------------------------------------------------------------------- AR531X # AR531X # AR531X # AR531X # setenv verify n AR531X # bootm bfc40000 ## Booting image at bfc40000 ... Image Name: Linux Kernel Image Created: 2003-10-30 6:12:30 UTC Image Type: MIPS Linux Kernel Image (gzip compressed) Data Size: 1439116 Bytes = 1.4 MB Load Address: 80002000 Entry Point: 80002000 Uncompressing Kernel Image ... OK No initrd ## Transferring control to Linux (at address 80002000) ...

Starting kernel ...

<4>SDBBP EJTAG debug exception - not handled yet, just ignored! <4>c0_depc = 44fca612, DEBUG = 0a00cc06 ----------------------------------------------------------------------------------------------- I check the code in Linux Kernel , they are interrupted by EJTAG . I don't know whey it will have such interrupt ? Then it just stop to go....
