mkboot utilities under vxworks

[f.pe...@staubli.com]

Hello TORNADO and vxworks gurus,

I have a x86 target with T2 (CP3) and vxworks5.4.
I try to initialise an ata flash disk from the shell with the command
-> mkbootAta (1,0,"bootrom.sys")

I get the flowing error:
Error during ioctl FIOCONTIG: 381200
value = -1 = 0xffffffff = mkboot.o_bss + 0xff0b4f7b

My flash is formated from dos before executing the mkbootAta from vx.

Any suggestion realy appreciated ......

thanks in advance

We had similar problems with some certain types of flash disks.
It seems the VxWorks filesystem is not able to find a large enough contigous
block on the disk to store the BOOTROM.SYS file. (This is what the IOCTL
that causes the failure should do).

We worked around as following

- vxcopy the bootrom_uncmp file to bootrom.sys with the command line tool on
the host
- boot the target with a dos disk
- vxsys the target (the vxsys.com utility runs under plain DOS, in contrast
to vxcopy.exe)
- copy the bootrom.sys file to the root of the (preferingly freshly
formatted) drive
- if you experience problems while loading the bootrom defrag the disk with
the msdos DEFRAG and be sure to select complete reorganization, to get the
BOOTROM.SYS file in one piece
- you can verify if the BOOTROM.SYS file is in one piece on the disk with
CHKDSK C:\BOOTROM.SYS
