Sam460LE 1.10 Ghz Pre-Order!

@amiganuts

I am using a Gigabyte pci-e Radeon 4650

works on uboot and AOS

What driver do I need for R7 240? I have Radeon HD 3.7 and Radeon Rx 2.12?

System will boot fine, I can move mouse but when I try to open partition or anything system will freeze instantly 😔.

@PixelHI

If you have seen "amigaos4" logo while booting, and even workbench loads up, then it means you use correct driver already.

It can be that lockup happens because of FAN not working , or sliding off from the CPU. When i have my not working, the system freezes right after i start to navigate the workbench.

Of course, it can be an issue with the GFX card itself, but less possible, as most of them were tested and works.

It also can be an issue with your Sata card : or the settings in the uboot for, or the card itself with the “bad” driver for. I remember Max says that some Sata cards works as expected, but some are known to be buggy with their drivers (on all hardware).

Will be nice to have serial cable plugged on, to see if kernel threw anything to serial when everything freezes.

I have r7 240 and 250, both behave the same and both tested under Windows. It's not a GPU.

I replaced Radeon HD and added RadeonRX to SD card with AmigaOS... and now it will actually show instalation screen for my 7750... (apparently included driver is not working). When I swap to Radeon Rx system will boot from SD card, but it will freeze when I try to open / do anything.

I have no idea what is an issue here.

EDIT: AmigaOS on SD is not modified, and I did not use SATA interface (I disconected all device) and it still froze.

BTW. I wrote it using Odyssey :).

@PixelHi

I cannot get my Biostar RX550 to work at all in the SAM460LE but it works fine in my X5040.

I was having weirdness with my graphics. If you read above, I would pulldown the little arrow on Odyssey, it would immediately freeze. When I used SysMon, the CPU would peg at 100%. I could not install Amistore because it would freeze immediately. Ztools wouldn't even find the GPX even though Ranger saw it I started from scratch again and used the CD and then installed Enhancer 2.1 and it. At that time, I was able to install Amistore and then able to open update and update the system and updater to update enhancer. It was then it started acting properly. However, my RX550 still does not display Uboot or Amiga4.1 screen.

The card that works is a Radeon R9 280 Sapphire.

It has been very stable now.

Maybe my X5000 files got mixed with the SAM460? Are Enhancers specific? I used the disk that i got in my AAA package suppose to be for the 1222 but I don't see anything that says 1222 specific.

@m3x

Thanks for your assistance .

Finally got My Sam460ex up and running today.

For some reason I cant get the Sam460ex to boot using the replacement U-Boot eeprom from A-Cube with U-boot 2015-b.
The image is good as I saved it and used it to re flash my original eeprom which allows the Sam460 to boot.

Also have the problem of no boot with my oldest eeprom from a damaged Sam460ex. this I also flashed with the same U-boot image form the newest ACube replacement that works with the original eeprom. Weird .

Took this long to get a eeprom programmer then further delay
in getting the PLCC-32 Socket to DIP-32 Adapter that was not actually included .
UPS also misplaced the incoming replacement eeprom from Acube for about a month.

Did some more testing today.

Re flashed an AT4BV040B from a Sam440ep-flex with Uboot 2015.b and that works .
Seems that that actual working eeprom from yesterday was actually from the old Sam460ex board and not the current one .

@Spectre660

You used an offline programmer to program the flash devices?

Did you also verify the devices after programming? (read back its contents and compare with the loadfile)

At least the ATMEL AT4BV040B contains a bootblock protection which prohibits erase/write when the protection is enabled.

There's only one version of the ATMEL AT4BV040B (except for package options). So if the ATMEL AT4BV040B has been programmed and verified, then there should be no reason why they do not work in a sam460. Unless there is a timing or voltage issue that shows up as a batch related issue.

@geennaam

Yes same write then verify process for all 3 chips with an offline programmer.
2 work and 1 does not .
also the replacement SST39lF040 chip from ACube does not.
Reads ok as I copied the contents and used to flash the 3
ATMEL AT4BV040B chips.

So your theories re "timing or voltage issue that shows up as a batch related issue" are on the table.

The update process for two of my ATMEL AT4BV040B failed with the ACube updater .
