The ppcboot is a very old version of the bootloader. Why don't you use the lastest version of the u-boot: u-boot-1.1.2?

Subject: [U-Boot-Users] Problem about sdram initialization!
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.
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:
addi r0, r10, in_ram - _start + EXC_OFF_SYS_RESET
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:
BR2(control SDRAM): 0x0000 0041
PSDMR: 0x2869 A452
Please give me a hand.
Thanks in advance!
