Problem with uboot on lite5200
Hi all, i am newbee in Linux PPC. i have problem with my lite5200 board. previously it has been installed with uboot. but now i dont receive any message from uboot in the serial line (serial line is ok with 115200 bps - tested). how can i re-flash the uboot inside the MPC5200? i use bdi2000, compiled the new uboot version 1.1.6 but didnt find out anyway to flash it inside the controller. thanks for the hint, ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
MPC8247 Boot Problem.
Dear all, I am using ELDK-3.0, and porting the linux-2.4.24 to my MPC8247 board, U-Boot-1.0.2 ran ok. Current problems as follows: 1. If turn on the data cache, the linux kernel can't start up, it hang when executing follows instruction: /* stack */ addir1,r2,TASK_UNION_SIZE li r0,0 stwur0,-STACK_FRAME_OVERHEAD(r1) in file arch/ppc/kernel/head.S. 2. If turn off the data cache, kernel can run until decompress the ramdisk, then decompress ramdisk failed. 3. The same kernel running ok on my old MPC8250 board. Expecting your answer and advice, thanks in advance! Best Regards!

MPC82XX and SATA hardisk performance.
Hi all, I use the PCI bus and PCI-SATA bridge SII3112 to expand two SATA port, my MPC8250 work frequency is CORE/CPM/BUS 200/133/66M, filesystem use ext2 under linux, i write a program to test the maxmium written speed, the result is about 60MBps/S, maybe it's too slow? Anyone who has experience can give me some advice? How can I increase the written speed? Best Regards! Leo.
