[microblaze-uclinux] no output if booting from Flash

[Vijai.S.Kumar@xxxxxxxxxxxxxxxx]

hello  elynum
I have seen ur mail posted on  Wed 19 Oct 2005 - 02:07 am about booting
uclinux from flash.
but that wae not opend on my system.
well i am giveing the step by step method but still we are in problems
plz help if u have done.
----------------------------------
we have downloaded new version of uClinux-2.4.x which spport the
feature to execute image directly from PROM.
but after fuseing image when we run directly from Flash, we are
not getting anything on hyperterminal.

the sequence of steps are as follows -

1.make menuconfig
   a) select vendor: -XIlinx and patform: -uclinux-auto
   b) we slect default all settings for kernel and user
      then after Ecs+save system asks
      model: - to which - Iselect ROM
      Size of Flash: - I select 4MB
      starting address of Flash: - 0xff800000 (I select this)
      size of Flash: -  0x00400000 (I select this)

2. make clean dep all

3.Now we download the image using XMD -

XMD% dow -data image.bin 0xfe000000

4. next we fuse the image to Flash.
    (our image mtd partition starts at 0xff800000 + 0x00100000
    becoz starting 0x00100000 size is used by Bootloader,Bootags,
    MAC and spare partition.)

5. we run the image using XMD: as

XMD% con 0xff800000
output on hupert: no output

XMD% con 0xff900000
output on hupert: no output

?????6. Now confusion and problems are as follows -

 ???a) we have to give con command from 0xff800000 or from
    0xff800000 + 0x00100000 (becoz of start for bootloader,args etc )

 ???b) I have to change some files to support XIP, allthough I
       have latest version of uClinux. (as u seggest for the last
       -old vrsion)

thanks in advance

vijai
