Wolfgang,
The BDI config file for the Yosemite board on the U-Boot manual doesn't work (I can't erase the full range of flash between 0xFC000000 to 0xFFFFFFFF), so I've been using the one provided by AMCC.
When I do a reset halt, the PC does get set to 0xFFFFFFFC (please see below). But GDB still goes straight to 0x00000000.
The BDI config file from the U-Boot manual only allocates 2MB of flash (there are 64MBs on this board). If I use this config file, the GDB goes to 0xdeadbeef (but the BDI telnet shows the correct 0xFFFFFFFC for the PC after a reset-halt).
U-Boot is fully operational after I flash it onto the board, regardless of which config file I use.
440EP>reset - TARGET: processing user reset request - TARGET: resetting target passed - TARGET: processing target startup .... - TARGET: core #0 PVR is 0x422218D4 - TARGET: processing target startup passed 440EP>halt Core number : 0 Core state : debug mode Debug entry cause : JTAG stop request Current PC : 0xfffffffc Current CR : 0x280fff82 Current MSR : 0x00002000 Current LR : 0x0ff9b084 440EP>
Probably your BDI config file needs adjusting. Try what you see when you use the telnet interface directly, i. e. where do you end up after a "reset halt" ?
Best regards,
