<DIV> Hi,I have a little problem with the ppcboot startup,the
BDI2000 can program ppcboot.bin into FLASH .Board information can print
through serial interface after the first initialization of board now.</DIV>
<DIV> But when it run to the function relocate_code(in the
/cpu/mpc8260/start.s),it don't run continually. Through LED on the board ,I
find that it stops at the code below:</DIV>
<DIV> </DIV>
<DIV>addi r0, r10, in_ram - _start +
EXC_OFF_SYS_RESET<BR>mtlr r0<BR>blr</DIV>
<DIV>in_ram:</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>The size of SDRAM size is 16MB,flash is 8MB,CPU is
MPC8250,and my costum board is like the board MPC8260ADS.Othe infomation with
my board is below:</DIV>
<DIV>CLKIN:33M <BR>MPTPR:0x10 <BR>PSRT:0x1900 <BR>BR2(control SDRAM): 0x0000
