That appears to be the problem. Funny. It appeared kind of random until I finally found that if I left the gFTP open from my Debian desktop machine and ran bootload the md5sum values would change and the files would be corrupted (giving me faults if I tried to insmod or run). But if I ensure the gFTP is closed the files remain uncorrupted and everything works well after the command is run. Thanks for pointing me in the right direction. I still have an issue or two with the rtai kernel rebooting... it works if I load it from redboot but not if I use the bootload executable (the non-rtai kernel works either way)... but I guess I need to look at how I built the kernel.
Thats very odd. I just tested a TS-7250 again and had no problem with the insmod. The insmod runs the module_init routine on load and that routine is like 6 lines of code and very generic. Could you verify the md5sum of your bootloader.o file? Here's mine: sh-2.05a# md5sum /lib/modules/2.4.26- ts11/kernel/drivers/char/bootloader.o ad729068562df0a42b5dc2a427cb189d /lib/modules/2.4.26- ts11/kernel/drivers/char/bootloader.o //Jesse Off --- In wrote: > > I tried to load bootloader.o with insmod and got the following: > (I'm running ts7250 2.4.26-ts11 #3) > > ---------------------------------- > /sbin/insmod bootloader.o > > Using bootloader.o > Warning: loading bootloader will taint the kerneUnable to handle kernel > NULL pointer dereference at virtual address 00000010 > l: non-GPL lpgd = c4094000 > icense - Pro[00000010] *pgd=prietary > 050b4801See http://w, *pmd = ww.tux.org/l050b4801kml/#export-, *pte = > tainted for 00000000information , *ppte = 00000000about tainte > d modules > Internal error: Oops: 7 > CPU: 0 > pc : [<c03400c4>] lr : [<c02be93c>] Tainted: P > sp : c10a7ee8 ip : 00000000 fp : c50fa380 > r10: 0018a1c0 r9 : c10a6000 r8 : ffffffea > r7 : c0372404 r6 : c037241c r5 : d4028b4c r4 : c039733c > r3 : 00000002 r2 : 80000013 r1 : 0000002f r0 : 00000010 > Flags: nzCv IRQs on FIQs on Mode SVC_32 Segment user > Control: C000317F Table: 04094000 DAC: 00000015 > Process insmod (pid: 86, stack limit = 0xc10a6368) > Stack: (0xc10a7ee8 to 0xc10a8000) > 7ee0: 00000060 ffffffea 00000000 d4028000 00000000 > d4028000 > 7f00: d10b1000 00000060 d4028380 00000000 c023b530 0000000a d10b1000 > c50ac000 > 7f20: d4036000 00000060 d402c000 d4028060 00000ca0 00000000 00000000 > 00000000 > 7f40: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 > 00000000 > 7f60: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 > 00000000 > 7f80: 00000000 00000028 00000ca0 0018a1c0 00000080 c022d704 c10a6000 > 00000ca0 > 7fa0: 00000000 c022d560 00000ca0 0018a1c0 00900080 0017f3f8 0018a1c0 > 00000000 > 7fc0: 00000028 00000ca0 0018a1c0 d4028000 0017f3f8 0008b0a0 00000ca0 > 7ffffe54 > 7fe0: 7fffda4c 7fffda40 0006aecc 2ac3f130 60000010 00900080 00000000 > 003bc001 > Backtrace: > Backtrace aborted due to bad frame pointer <c50fa380> > Code: e1a00000 e1a00000 e1a00000 e20110ff (e4d02001) > Segmentation fault > ---------------------------------- > > > > > > > "Jesse Off" <> > Sent by: > 11/29/2006 04:33 PM > Please respond to > > > > To > > cc > > Subject > [ts-7000] new TS-7000 bootloader (Linux booting Linux) > > > > > > > Hey all, > > We've just written a utility to allow arbitrary loading and > execution of kernels within an already booted Linux.
