[U-Boot] which u-boot build config to choose for kirkwood?

[U-Boot] which u-boot build config to choose for kirkwood?

[JPT]

Hi,

I finally succeeded in booting my kirkwood board from UART. But this did 
not help. The Netgear uboot 1.1.4 still hangs after loading the network 
hardware. Since I was messing with the uboot-env before it broke, this 
is most likely the cause of the problems.

To access the uboot-env I've got two alternatives I can think of:
- Boot a current mainline U-boot to get the uboot console and access to 
the uboot-env in NAND.

- Boot into (kirkwood?) debug console using the magic bytes. I once 
achieved to get it, but since I don't. And I don't know anything about 
how to use it. (any hints?)
Kirkwood UART boot is integrated into the current mainline uboot, but 
debug console isn't, right?

Well, I decided to build uboot myself. To access uboot env in NAND I 
only need working: CPU, NAND, RAM, UART. Correct?
Could you please give some hints on how to choose the right config?

Most detailed hw info I got from: http://natisbad.org/NAS

CPU:
Marvell 82F6282 SoC (aka ARMADA 300) from Kirkwood family. 
ARMv5TE-compatible
cat /proc/cpuinfo
Processor       : Feroceon 88FR131 rev 1 (v5l)
Features        : swp half thumb fastmult edsp
CPU implementer : 0x56
CPU architecture: 5TE
CPU variant     : 0x2
CPU part        : 0x131
CPU revision    : 1
Hardware        : Feroceon-KW

RAM
2x 128MB DDR3 1333 Hynix H5TQ1G83DFR-H9C @ 533Mhz?

NAND
Hynix H27U1G8F2BTR

UART
integrated into Marvell SoC

I am not sure about this one, and if I need it:
ATMEL AT25F512B-SSH
512 Kilobit SPI flash.


btw, is uboot-env 1.1.4 compatible to recent uboot?


thanks,

Jan

[U-Boot] Question about Automatic Updates

[TigerLiu at viatech.com.cn]

Hi, experts:
I found an Automatic Updates digest in this web page:
http://www.denx.de/wiki/view/U-Bootdoc/AutomaticUpdates

So, my question is:
1. Can uboot support this feature now?
   I could not find key word "firmware.img" etc in u-boot source code
package.

Best wishes,

This has been implemented (actually in a number of veriants) for
several boards in U-Boot.

Most of this is usually done as shell scripts run by U-Boot. These
scripts are usually proprietary code ant not part of the U-Boot
distribution.

Mainline U-Boot contains all the needed features, and implementing
such an update mechanism is relatively straightforward.

[U-Boot] build succeeded, what now?

[JPT]

Hi,

Ok, I succeeded in building, used mv88f6281gtw_ge_config.
I cannot find any hints on how to continue in the manual.
So I tried with what I already know or simply guessed.

I added a header to the file u-boot.bin using the netgear provided doimage.

After uploading the image, nothing happens.

I am wondering:
- shouldn't there be a device tree to provide to linux?
- the uboot.bin is 300KiB. the old netgear one was 1,5MiB. How comes?
- is there any way to separate the original rom into pieces like uboot 
binary, device tree, etc?

thanks,

Jan

[U-Boot] how to troubleshoot when u-boot is stuck

[JPT]

I did not succeed trying the "build myself" way yet.
Maybe someone is able to give a hint.

Since I messed with the u-boot-env from linux prompt, u-boot stops right 
after "Net:   egiga0 [PRIME]" which is just before "Hit any key to stop 
autoboot"
Isn't there anything I can do? Anything I can learn from this?

Any README doc for using or creating automation for specific board.
Request for help.

Thanks,
Jagan.

As mentioned, most of the existing scripts are proprietary code and
not released as part of the U-Boot distribution.

As for the public parts, search for example for auto_update.[ch] in
the source tree...
