SAM460EX going black screen after official uboot2015b update
Just popping in

Dear Amigans. I got stucked.

Last weekend I finally found time to build up
my SAM460EX with 502 GFX onboard.

I unpacked the uboot 2015b archive I bought from ACube Shop
and went to OS4.1 to find out the corresponding clock
my Sam had. So it showed me 55MHz.

After that I chose the update_460_2015b.iso and burned with
1x speed the .iso to a CD.
After that I put in the CD and first changed boot order to SIL3114 sata_DVD.
The ubootupdater immediately kicked in with a minimalistic menu after choosing ubootupdater it erased and after wrote the new uboot without any problems.

After removal of CD and reset/power off the SAM seems „dead“. But at least on Mainboard power led showed green and there is a row of leds where now after uboot update only one (the last in the row when you look at it)
is shining in green. No vga/hdmi output either on onboard 502 or on Radeon pci/pci-e after update.
Blackscreen an no fancy new uboot Menu

Is it bricked?
Any Ideas 💡 ?

Since Sam460s bios can be replaced with a new one,it is not bricked. Please ask for a new bios chip from ACube.

Latest release uboot did not work with my Sam460ex. So I had to downgrade bios chip with an eeprom programmer device.

Perhaps it just can’t initialize the screen hock up a null modem cable to the sam460 and use Putty or some other serial terminal, too see if you can get into UBOOT.

There can also be some additional debug info there you can’t see on your screen normally.

Sorry to hear that.
Can you come at Amiga38 with your board so that we can replace the Uboot ship?

As far as I know version 2015b is not 100% compatible with Sam460ex.

Hi 👋🏼. Yes I will be there and I do appreciate your offer.
I’ll bring my Sam460ex to the show.

Maybe it’s a good finding that at least two original SAM460EX with onboard gfx rendered dead after upgrading with newest 2015b uboot. While Update processs returned no errors and confirmed to do a reset after cdrom media removal.

Maybe you nice guys @ acube need to investigate?

Thanks for your support looking forward to the awesome Amiga38 show.

Hope after investigating our issue we (and maybe others) can
benefit from newest uboot.

Thank You in advance.

Is that true that I don’t loose
onboard 502 gfx with SAM460EX
after installing latest and greatest
uboot2015b or newer?
