You have one of the few early Sam460ex boards with a base clock of 66 MHz, which at the time were mostly given to developers.
Unfortunately, the 60 MHz version of the u-boot installer will not work on your board, you need a custom installer version.

In addition, the SATA 3112 controller is unstable when used on the Sam460ex, so we recommend the 3512 or 3114 models, or, after updating to the latest version of u-boot, the 3132.

PS: Since you are updating from such an old version of u-boot, you may need to update to an intermediate version first, and only then install the latest version.

The Sil3132 controller is not recognized at all on the PCIe bus, so this is not the same situation you reported with the AmigaOne example.
It could be an incompatibility between the PCIe bridge and the controller, or an incorrect configuration of the PCIe bridge.

Since the controller is not visible at all, the driver cannot do anything about it.

@skygecko

We tested the driver with the same noname black card used by Sailor.
Other reports suggest that cards with external SATA ports do not work, raising suspicions about their BIOS.

Another note: X5000 owners report that the card is not recognized at all on the PCIe bus. It is unclear whether there is a bug in the X5000 Uboot or some kind of hardware incompatibility.

@tao

someone is already working on it

@sailor

just format the SD ard on a linux machine with:

mke2fs -t ext2 /dev/usbX

where usbX is your USB SD card, then copy kernel and dtb, no need to add slb_v2, or parthenope, and no RDB partitioning.

@graff

it's possible to do the u-boot update/downgrade via serial terminal, connectiong a null modem cable to a PC, settings 115200 8N1.

In order to do the update from the serial terminal, under AmigaOS4.1, you need to enter before the following commands from the Shell:

nvsetenv stdin serial
nvsetenv stdout serial

and then reboot.

From this point, when back to u-boot, you can stop the boot sequence pressing 'q' key at the countdown, then enter the commands to upgrade/downgrade u-boot via TFTP.

When finished, reboot to AmigaOS4.1 and from Shell enter:

nvsetenv stdin usbkbd
nvsetenv stdout vga

to restore the original settings.

Hope this helps

@sacc-dude

To see the new interface you need to enter uboot menu and set:

Video Options -> Console -> Silent

@kas1e

There were some improvements in read/write benchmarks, but I don't remember the exact figures at the moment.

@kas1e

you may try to enable prefetch on the 8112, like I've done in u-boot for the Sam440-flex board:

@joerg

yes, you're right, it was a copy/paste error, I've modified the above post, thanks !

@kishigo

try setting stdin and stdout to serial, you can do it from the AOS4.1 shell:


Remember to put them to the original values when done:

@kas1e

Nice video, thanks !

PS: the new U-Boot version supports all Sam460 models

@kas1e

yes, it supports only ext2fs, fat support was removed to save space on the 512 Kb boot eeprom, maybe we can add it back again with a new u-boot version.

@kas1e

if you need to interrupt the boot countdown and go into u-boot shell, you may press 'q' instead of ESC

@kas1e

setenv stdin serial

@all

This is the explanation of what happened:

- we sold very few Audigy FX cards (less than 10), and then took them off as availability from our shop because there was no demand
- the sound cards were not sold with any driver included, at the time it was still possible to download the driver from OS4Depot
- the audio driver was included on the SD card we supply with the Sam460 boards to help users install the operating system and other utilities easily and as quickly as possible, a kind of 'bonus pack.' As soon as we were alerted to the problem with the audio driver, we removed it
- Our mistake was to include the driver without having read the readme

We are sorry to learn that things were misunderstood. We make our apologies to geennaam and the Amiga community.
We will make sure that things will not happen again in the future.
In any case, we invite you to contact us directly through our contacts available at www.acube-systems.com

@balaton

I've found only some snippets of code from the AmigaOneG3SE u-boot source code, maybe the following code may help:


and


and more

@arfcarl

In our tests, the SIL 3112 is unreliable when used with a Sam460 board, the exact cause is unkwown.

@balaton

There is a Pericom 8150B PCI Bridge on Sam440ep mini-itx and flex boards, maybe it's testing it ?

@Gebrochen

Try the Sam440ep_setup utility from OS4Depot:

http://os4depot.net/share/utility/shell/sam440ep_setup.lha

if it help with your dragging open drawer windows slowness, which is in part due the HD 5450 used which has a PCI-PCIe bridge onboard.
