Hello, I'm using my custom board (PPC 440GX) and working with U-boot1.1.2 and Linux kernel 2.6.12. Now I have problems with debugging. When I start U-boot from Flash, it's working fine. But when I try debugging U-boot with BDI2000, it always hangs on PC: 0x00001300. ppc>go ppc>halt Core number :0 Core state :debug mode Debug entry cause :JTAG stop request Current PC :0x00001300 Current CR :0x22004022 Current MSR :0x00000000 Current LR :0xfffff144 ppc> Thanks for any help, Bashier
