Hi everybody,
I'm using a BDI2000 to debug u-boot on a LITE5200 board. I've got some problems with breakpoints and stepping when the MPC5200 USB is running.
When the USB is disabled, breakpoints are working, and I've got the following display on the BDI2000 terminal :
BDI>bi 0x3f9732c Breakpoint identification is 1 BDI>break Breakpoint mode is SOFT BDI>go - Target MBAR is 0xF0000000 - Target XLBA is 0x80002006 - TARGET: stopped BDI>in Target CPU : MPC8280/MGT5200 (Zeppo) Target state : debug mode Debug entry cause : instruction address breakpoint Current PC : 0x03f9732c Current CR : 0x24008004 Current MSR : 0x00001002 Current LR : 0x03fa2028 BDI>go - Target MBAR is 0xF0000000 - Target XLBA is 0x80002006 BDI>
When the USB is enabled and the breakpoint is reached, if I try to continue my program, the MPC5200 stops again and I've got the following display : BDI>go - Target MBAR is 0xF0000000 - Target XLBA is 0x80002006 - Target MBAR is 0xF0000000 - Target XLBA is 0x00000000 - TARGET: stopped BDI> BDI>go - Target MBAR is 0xF0000000 - Target XLBA is 0x00000000 - Target MBAR is 0xF0000000 - Target XLBA is 0x00000000 - TARGET: stopped BDI>in Target CPU : MPC8280/MGT5200 (Zeppo) Target state : debug mode Debug entry cause : <reserved 0> Current PC : 0x03f97324 Current CR : 0x24008004 Current MSR : 0x00001002 Current LR : 0x03fa2028
It's impossible to continue the program.
Any suggestion ?
Best regards
