Rogan Dawes - March 18, 2011, 7:39 p.m.
From: Rogan Dawes <rogan@dawes.za.net>

Based on that of the edminiv2, with a few additions

The image is configured to boot vendor kernels seamlessly.
i.e. the kernel boot logs should be identical between the vendor
bootloader and this mainline version.

Note that the vendor flash layout does not allow space for saving
environment variables. All env variables are compiled in to the
vendor bootloader, and saveenv is not provided.

According to the flash layout, the smallest segments are at the
start of the flash chip, which conflicts with mtd0, used to save
the NAS configuration by the vendor firmware. Consequently, if
you intend to keep the vendor firmware, do not save any additional
environment variables, or change existing ones.

GPIO pins are not configured, as they do not match the layout for
the EDMiniv2. That configuration causes the kernel to shutdown, as
it detects that the power button is pressed.

With relocation, you must set TEXT_BASE to the value you start
the image, so please try to set TEXT_BASE = load_addr.

Also, if you do a ram image, don;t forget that with relocation
the u-boot image gets relocated to the end of ram, so don;t choose
a TEXT_BASE near the end of ram.

If that not helps, you maybe need a debugger ...

Hi Heiko,

I did see that, and thought it might have something to do with it. I
also tried building a version with the TEXT_BASE at 0x100000, but had
exactly the same result.

It sounds like a debugger will be my only option. Fortunately, I should
be getting a Segger J-Link JTAG adapter on Tuesday, and then maybe I can
figure out what is going on.

Regards,

Rogan

Hi Heiko,

It is clear now that I *am* an idiot.

I was loading the uImage to 0x100000, but the uImage was configured to
be copied to 0x3000000 before being started by the vendor u-boot.

Setting TEXT_BASE to 0x3000000 allowed me to start my chainloaded "on
top of master" u-boot.

Now all I need is to figure out the right way to patch the CFI code to
handle my 8-bit/16-bit configuration, and I should be ready to submit a
working configuration.

Thanks for your help.

Simply: it does not.

When Linux starts running, U-Boot is gone and dead; nothing of it
survives the boot of Linux except for the parameters passed to the
Linux kernel.

Linux has no idea which boot loader has been used to start it, nor
can Linux call any functions from the boot loader.

Thanks for your reply very much. 

In my scenario, I want to write the panic info into the flash, but the panic
is caused by interrupt routine, I cannot access the flash, so I think that
if the flash-write function from u-boot can be called, the issue should be
resolved. 

Any other comments? 


Thanks!
Shuyou

If the system panics, you must not assume that there is any working
code left that is capable of writing to flash memory.

I told you before that there is no U-Boot code available anywhere once
Linux started execution.

You may look into the shared log buffer feature - if Linux dumps it's
log messages into it's log buffer, this information can be picked up
by U-Boot from there, and even passed on to the next booting Linux
kernel.

Best regards,

Wolfgang Denk
