Hi All,
I am using U-Boot with a Linux kernel version 2.4.27-1.3.3-432 on mpc8248
based board, but the last message I see is "Uncompressing Kernel Image ...
OK" and Then the system hangs. I traced the code and realised that it stops
when it makes a call to "(*kernel) (kbd, initrd_start, initrd_end,
cmd_start, cmd_end);" (in file u-boot/common/cmd_bootm.c)
As i searched through the archive i found a similar problem and had comments
asking to verify the following:
1. bd_info
2. IMAP_ADDR and CFG_IMMR should have the same value
3. clock speed saved in env
My bd_info is:
kbd->bi_memstart: 0
kbd->bi_memsize: 2000000 - 16MB
kbd->bi_flashstart: ff000000
kbd->bi_flashoffset: 0
kbd->bi_sramstart: 0
kbd->bi_sramsize: 0
kbd->bi_immr_base: 0f000000
kbd->bi_bootflags: 1
kbd->bi_ip_addr: c0a801de in HEX
kbd->bi_enetaddr: 7ffbd8 in HEX
kbd->bi_ethspeed: 2bd6 in HEX
kbd->bi_intfreq: 15a in HEX
kbd->bi_busfreq: 63 in HEX
kbd->bi_cpmfreq: c6 in HEX
kbd->bi_brgfreq: 18 in HEX
kbd->bi_sccfreq: 63 in HEX
kbd->bi_vco: 18c in HEX
kbd->bi_baudrate: 1c200 in HEX
which i believe is correct. The value of IMAP_ADDR in
linux/arch/ppc/platforms/boardname.h and u-boot/include/configs/boardname.h
is 0x0f000000 and i dont have the clock setting saved in my env.
I could not figure out any more cracks because of which Linux would not
boot. Looking for your help on this.
Regards,
Vikrant

You need to move your IMMR into kernel address space which starts at
0xC0000000 (IMMR = 0xF0000000 is a good candidate). I would further
recommend that you set the IMMR to be initialized to this value using
the HRCW rather than changing it via u-boot initialization -- one less
thing to go wrong.

The question is not if it is correct, but if it is IDENTICAL to the
structure as used by the Linux kernel.

Appreciate your quick responses on this.....BUT...............
Having already read your page (the link to which you provided) I double
checked on the bd_info structure in both linux and u-boot. I even worked out
the clocks_in_mhz....neither of them worked.
Somebody suggested I use gd->bd instead of kbd in common/cmd_bootm.c of
uboot when making the kernel call. That is use
(*kernel) (gd->bd, initrd_start, initrd_end, cmd_start, cmd_end);
"INSTEAD OF"
(*kernel) (kbd, initrd_start, initrd_end, cmd_start, cmd_end);
This didn't help either......!!!!!
Is there some thing else I am failing to pinpoint....
Just a reminder: the reference board is an Embedded Planet board (EP8248)
and the one I am trying to port is 8248 custom board. The linux image I am
using for my board works perfectly with the reference board (EP8248)....

Vikrant

B*llsh*t.
Jerry exactly pointed out why your board cannot boot: your memory map
is broken. Fix your IMMR location.

u-boot (in HRCW) and the linux part, still its hanging after displaying the
message

As Wolfgang rightly pointed out, For Linux Kernel to boot properly IMMR
shouldn't be at 0x0f000000 but it should be above 0xc0000000. Try
setting 0xf0000000 for your IMMR, it should work.

Are you absolutely sure that your SDRAM has been initialized
correctly?

^^^^^^^^^
This looks somewhat corrupted to me.
I speculate that your RAM fails in burst mode. Try disabling burst
mode (set BI bit in memory controller) and/or caches in Linux; if it
starts to work then you know where to look after.
Best regards,
Wolfgang Denk

Hi All,
SDRAM on the reference board is initialized properly now..
It has been verified. The dump value which I am getting now is ...

Are you absolutely sure that your SDRAM has been initialized
correctly?

This looks somewhat corrupted to me.
I speculate that your RAM fails in burst mode. Try disabling burst
mode (set BI bit in memory controller) and/or caches in Linux; if it
starts to work then you know where to look after.

How do you know that?

Ummm... the _real_ verification that SDRAM is working is that you get
a working Linux system.
I still believe that you might have problems in burst mode. Please
see the FAQ.
[And BTW: this is the U-Boot mailing list, and Linux problems are not
exactly on topic here.]

It's a small world, but I wouldn't want to paint it.
