Quite unusual in OS4 land to handle things in a good way with providing a source of amigaos4 related parts too, without anyone asking and crying for them. And support of RadeonRX is top too, thanks a lot !

dang..i have a rx 470 8gb laying around. but not on the test list

Where can it be found?

Doesn't seem to work with the following -

Docooler Yeston RX560-4G D5 LP Graphics Card Gaming Graphic Card 1200/6000MHz 4G/128bit/GDDR5 Memory VGA+HDMI+DVI-D Output Ports

Sam460 no longer boots up with that card.
Will still boot up with a HD5450.


Cheers

The RX 470 is very similar to the RX 570, we didn't had any to test it on, you may give it a try, before doing so, set the x86emu to 'Medium' in Video Options, or in alternative from the u-boot shell:

] setenv x86emu 2
] saveenv

@TiredOfLife

there was a similar problem with a RX 460 card, which was solved setting the x86emu to 'Medium' in Video Options, or in alternative from the u-boot shell:

] setenv x86emu 2
] saveenv

That worked.

Cheers

awesome stuff ACube! I miss U-Boot when I had my Samflex@800 and wish that you guys had set up U-Boot on the X1000 too instead of the CFE we got stuck with

thanks..will try that when im back from work

Hello, I'm trying to get into U-Boot to perform update. I attached a serial cable to my Amiga w/460 LE, I can see verbage re: U-boot on my terminal screen, but it stops at VESA: OK. I press q, that doesn't do anything. I press esc, that doesn't do any thing. I've checked my Putty settings and they have 115200, 8 data bits, 1 stop bits, parity none, flow control none. Nothing seems to work. If I'm missing anything please let me know. Thank you.

@kishigo
It can be or not working serial cable, or you have setenv "stdout" set to anything but not to serial (like to vga). Be sure that you press esc or q, on correct keyboard too: if you have environment "stdin" set to usbkbd, then esc and q will works from usb keyboard only. To make it works from putty, you had to set "stdin" environment variable to serial too (together with "flow control" to "none" in putty itself)
