Sam460LE 1.10 Ghz Pre-Order!

@m3x & SinanSam460

Thanks.

Found the bios chip from my first Sam460ex .
Managed to get it to boot using this one.
Pondering my options for the update.

will try to find a working dvd drive .
And work slower if I do attempt the U-Boot Update .

The socket on my board has always seemed to be a bit flaky.
Have had to put pressure on the chip to get the board to boot from time to time over the years.
Had the same issue with the old chip that I just installed also .
Made several attempt at re inserting the chip before it worked consistently.

@M3x & SinanSam460

There is definitely a problem of some sort .

Updating via DVD drive using the "55" version .
no error but no boot after pressing "R" at the end of the process.

If you have an older card like RadeonHD 65xxx or 77xx series, you can boot AmigaOS4 and then downgrade to 2015a.

I downgraded to 2015a everything is fine again..

@SinanSam460

The eeprom rewrite seems to be failing or writing a bad image
so the board does not reach of finish the initializing stage.
The red and orange lights don't flash .
.

Has anyone (outside of Acube) done a successful upgrade? I have a Sam460ex here but don't dare to upgrade under current premises.

here another failure bricked my sam460ex ,
did all the steps first checked which version i needed it was 50 so i burned the 50 version iso and boot it well so far so good then it hangs nothing for about 15min nothing reset and bang dead black screen .
thanks for nothing. how do i get a working uboot chip ??

@m3x

is it possible to get a new uboot chip from the 2015,a uboot please ?

@Spectre660

where is the uboot chip located on the sam460ex is that that little chippie by the atx power socket ?

@klapdeur and all

we'll send a replacement uboot bios to all affected users.
Just send an email to info@acube-systems.com with your board serial number and full shipping address.

@m3x

Great to hear that.

-J is for PLCC.

Is a 39VF040 usable as a replacement for 49BV040?

If this chip from SST, then yes, you can use it, but to program it you need to use the 2015b updater, since support for this model was added only with this release.

@SinanSam460

Same ATMEL AT49BV040B on my board .

@m3x

Yes, it's the SST39VF040 I have.

Could it be that it is the AT49F040 and AT49BV040B that are causing the problem due to its "variable sector size" and option to lock the boot block? Or are other/all flash types affected by the problem?

With which voltage is the flash memory driven by the Sam460; 3 or 5 Volt?

@arfcarl

No, the AT49xxx is used on almost all Sam440 / Sam460 boards.

I was so hoping to get Sam before Christmas, now I'm quite sure it will not happen this year 😔.

@PixelHi

Sorry to hear that. Do you know if it has been sent?

@m3x

Any updates by chance on the shipping process? 😊

I’ll be sure to post here whenever I get a notification that my board is sent, fingers crossed that something happens here in the next week or two. I’m located in the US, so maybe that would play a role in how long it takes to get shipped out?

Wishing everyone a Happy New Year!
