I have not followed u-boot (we're still using modified ppc-boot v1.1.5) but if it is anything like ppc-boot, and that the kernel is anything like what we have (MV kernel 2.4.19 pre-7) then the board info structure and cmd line isn't being passed to the kernel (or more precisely, kernel isn't paying attention to it.) We made some patches to pull in the whole board info and cmd line. Be careful as the MV kernel hard coded a memory location in flash where it fetches Ethernet MAC address. The following assumes you are using ppc-boot. Since u-boot is more or less a descendent of ppc-boot, it is PROBABLY not too different. Search for ebony_setup_arch in arch/ppc directory and its subdirectories. you'll see a reference to ioremap64 EBONY_VPD_BASE where it memcpy the hardwired Ethernet address from some location in flash. Search for platform_init in the same general area. you will see a reference to parse_bootinfo which really does nothing for ppc-boot. You will need to replace it with something friendlier to ppc-boot. #ifdef __ARIODATA__ void __init parse_ppcboot_boardinfo(unsigned long r3, unsigned long r4, unsigned long r5, unsigned long r6, unsigned long r7) { if (r3) { memcpy((void *) __res, (void *) (r3 + KERNELBASE), sizeof (bd_t)); } #if defined(CONFIG_BLK_DEV_INITRD) /* * If the init RAM disk has been configured in, and there's a valid * starting address for it, set it up. */ if (r4) { initrd_start = r4 + KERNELBASE; initrd_end = r5 + KERNELBASE; } #endif /* CONFIG_BLK_DEV_INITRD */ /* Copy the kernel command line arguments to a safe place. */ if (r6) { *(char *) (r7 + KERNELBASE) = 0; strcpy(cmd_line, (char *) (r6 + KERNELBASE)); } } #endif void __init platform_init(unsigned long r3, unsigned long r4, unsigned long r5, unsigned long r6, unsigned long r7) { #ifdef __ARIODATA__ parse_ppcboot_boardinfo( r3, r4, r5, r6, r7 ); #else parse_bootinfo((struct bi_record *) (r3 + KERNELBASE)); #endif ppc_md.setup_arch = ebony_setup_arch; ppc_md.show_cpuinfo = ebony_show_cpuinfo; ppc_md.init_IRQ = ebony_init_irq; ppc_md.get_irq = NULL; /* Set in ppc4xx_pic_init() */ . . . You will also need to lift the board info structure from ppc-boot into the kernel; the board info structure is in ppcboot.h and needs to be copy into include/asm/ibm440.h. -----Original Message----- From: [EMAIL PROTECTED] [mailto:owner-linuxppc-embedded at lists.linuxppc.org]On Behalf Of brian.auld at adic.com Sent: Tuesday, February 04, 2003 11:40 AM To: linuxppc-embedded at lists.linuxppc.org Subject: Kernel boot: 'Kernel command line' not getting bootargs????? Ebony/440GP progress update. I'm almost there ... I can smell it, I can taste it, I can hear it .... but I just can't see or feel it yet. Wolfgang mentioned this in a previous post. As everyone knows, appropriate bootargs need to be passed for the kernel to boot with an nfs-mounted root filesystem. I've triple checked everything and am 99.9999% sure I'm setting the bootargs appropriately. For some reason, whenever I try booting, the 'Kernel command line:' always says 'ip=on'. I searched the archives and couldn't anyone that had a similar problem. I 'll attach my boot log with a printout of my u-boot env vars along the way: ************************************************************************ * ************************************************************************ * *************************** BOOT LOG ********************************* ************************************************************************ * ************************************************************************ * U-Boot 0.2.0 (Jan 31 2003 - 05:12:55) IBM PowerPC 440 Rev.
