Hello, first of all, I am a newbie in embedded linux systems.
I'm trying to boot a board based on a MPC8560 (with a e500 core). I'm using a RS232 console via a debug module connected to the SCC1 port of the 8560. The boot loader is U-Boot. It appears that the transfert of the kernel from the host to target is OK (I'm using TFTP). Problems begin when I try to execute the kernel. The system appears to be frozen. I don't know if the board is really frozen or if I have "only" lost the console. I suspect that my error is situated in the load/execution addresses. I've tried different couples of values : 0/0, 100000/100000, 10000/10000, 200000/200000, etc... I've also tried different file format (uImage, zImage.elf, zImage.s ...) I've tried two distributions : ELINOS and DENX. I don't know what's happened because I lose the console . Here is the result of one of my tests : -> niot 0 Client IP Address (0 for unknown) = 192.168.001.126 ? Client address mask (0 for unknown) = 255.255.255.000 ? Server IP Address (0 for unknown) = 192.168.001.127 ? File Format S(rec)/I(ntel)/B(in)/E(lf) = B ? e Boot File Name (NULL for unknown) = pimage ? zimage.elf Boot File Load address = 80000 ? 0 Boot File Execution address = 80000 ? 100000 Data update in progress... -> nbo 0 Initialize ETH 0 in progress... Physical link is up at 100f. TFTP parameters : Client IP Address 192.168.001.126 Server IP Address 192.168.001.127 Boot File Format E Boot File Name zimage.elf Boot File Load address 0 Boot File Execution address 100000 TFTP load in progress... Packets : 2065 ELF information : Loading .text @ 0x00800000 : 18620 bytes Loading .data @ 0x00805000 : 966656 bytes Clearing .bss @ 0x008F1000 : 8500 bytes Bytes received = 1057082, Bytes loaded = 0 Low address = 800000, High address = 7FFFFF After that, the console is died ! I could use some help in trying to understand what's going on. Regards, Micka?l
