problems ..to boot linux 2.4.4 on fads mpc860 please help!!!!!!!!
Hi there! I hope this helps... First of all, a coleague managed to make a 850FADS board work properly, so the credit is his. We're using PPCBoot 1.2 and kernel-2.4.20pre1. The first thing is to make sure that the ppcboot environment variable clocks_in_mhz IS NOT DEFINED. It would NOT exist, not be defined as 0 or 1. It changes the clock dividers in the processor that is not good. This should make the kernel boot at least with a ramdisk. If you have trouble to make the ethernet interface work, as we did, you should edit the include/asm-ppc/commproc.h and arch/ppc/platforms/fads.h files. In the first file, you should add the following: /*** FADS / #ifdef CONFIG_FADS /* This ENET stuff is for the MPC850SAR with ethernet on SCC2. Some of * this may be unique to the FADS850SAR configuration. * Note TENA is on Port B. */ #define PA_ENET_RXD ((ushort)0x0004)/* PA 13 */ #define PA_ENET_TXD ((ushort)0x0008)/* PA 12 */ #define PA_ENET_RCLK((ushort)0x0200)/* PA 6 */ #define PA_ENET_TCLK((ushort)0x0800)/* PA 4 */ #define PB_ENET_TENA((uint)0x2000) /* PB 18 */ #define PC_ENET_CLSN((ushort)0x0040)/* PC 9 */ #define PC_ENET_RENA((ushort)0x0080)/* PC 8 */ #define SICR_ENET_MASK ((uint)0xff00) #define SICR_ENET_CLKRT ((uint)0x2f00) /* RCLK-CLK2, TCLK-CLK4 */ #endif /* CONFIG_FADS */ It should be put together with the other boards' definitions. The fads.h file shoud be edited in these definitions: /*** defines taken from PPCBoot 1.2 ***/ #define BCSR_ADDR ((uint) 0x0210) #define BCSR_SIZE ((uint)(64 * 1024)) #define BCSR0 ((uint) (BCSR_ADDR + 00)) #define BCSR1 ((uint) (BCSR_ADDR + 0x04)) #define BCSR2 ((uint) (BCSR_ADDR + 0x08)) #define BCSR3 ((uint) (BCSR_ADDR + 0x0c)) #define BCSR4 ((uint) (BCSR_ADDR + 0x10)) /*** ***/ That should do the trick. Again, we are using a FADS850SAR board, which is not the same you have, but the spirit of the whole thing is to take the info from a working ppcboot to the kernel.

Hello, I had read this from the readme file CFG_IMMR: Physical address of the Internal Memory Mapped Register; DO NOT CHANGE! (11-4) [MPC8xx systems only] and found that in file /ppcboot /include/ config_FADS860T.h #define CFG_IMMR0xFF00 #define CFG_IMMR_SIZE ((uint)(64 * 1024)) and linux-kernel/include/asm-ppc/fads.h #define IMAP_ADDR ((uint)0xff00) #define IMAP_SIZE ((uint)(64 * 1024)) Are the values 0xff00 okay for fads board.. I am sure the above #defines satisfies the rule Just make sure your machine specific header file (for instance include/asm-ppc/tqm8xx.h) includes the same definition of the Board Information structure as we define in include/ppcboot.h, and make sure that your definition of IMAP_ADDR uses the same value as your PPCBoot configuration in CFG_IMMR. MY main problem is that the fadsboard is not booting up it hangs after Uncompressing Kernel Image OK I have checked the faq at the denx site ..and have done those changes also but of no use...I have attatched the config file after doing menuconfig ..if there is any errors possibly please let me know.. also after the kernel compiles i opened the vmlinux file and saw somwhere in the middle i found these warnings.. ** */usr/src/linux-2.4.4-2002-03-21/include/linux/mount.h.../usr/src/linux-2.4.4-2002-03-21/include .init=...Kernel command line: %s 2initrd overwritten (0x%08lx 0x%08lx) - disabling it. ..POSIX conformance testing by UNIFIX linuxrc./dev/console/linuxrc/initrd.3Change root to /initrd: error %d Warning: unable to open an initial console. /sbin/init../etc/init.../bin/init.../bin/sh.No init found.
