Hyperion U-boot version, DMA - fix

Post by sailorMH »

Hi,

I got from colleague AmigaOne XE. And I have some questions.

1. What is correct U-Boot version from Hyperion?
On Hyperion download site is written "AmigaOne Firmware Update *05-Mar-2005*"
And version which is on my AmigaOne is: U-Boot 1.1.1 (Mar 3 2005 - 16:42:53)
This is two days difference. Is it hotfix or some mistake?
Please do somebody have AmigaOne with last Hyperion U-Boot and can check the version from computer?
Can I flash it?
I also have Micro with U-Boot 1.2.0 and it is working perfectly. Is there way howto download U-Boot without removing the ROM? Then I can flash XE with newer experimental U-Boot.

2. My board is DMA fix.
There viewtopic.php?f=16&t=1889 is perfect explanation from tonyw what DMA fix is.
Is possible to do Un-Fix ?
Have somebody exact information which tracks were cutted?
I want to made some experiments and need to use PCI 66MHz slot.
Or, if somebody have unfixed AmigaOne ;-)

1 - iirc the two day difference comes simply from the fact that uboot was compiled on the 3rd of march, but officially released two days later.

2. Everything is possible, the question is
a) will you find someone who has the blueprints of the fix, the means and skill and is willing to un-fix
and
b) are *you* willing to probably brick a perfectly fine board?

Good luck

@raziel
thanks, number6 also confirm this. It is good news, I cannot reflash it.
and no, I don't want to brick it. I want to improve it ;-). I know, it is the risk, but upto now I didn't destroy any of my old computers.
