I guess it doesn't help to remove all USB peripherals? Keyboard, mouse etc.

Just grasping at straws at this point.

@Hitman: Can you reach the boot menu, or does it hang before you reach that stage?

@tekmage Wasn't it 1000, not 1500?

I guess the first batch will be 100 or maybe 200.

@OlafS3

Two more weeks.

Use 3.8.

Why: less, if any, problems.

@amiganuts

Yes, and I will have a look myself and try to set the MTU to 1500 (unless not already set to that).

Ethernet frame size 1518 = MTU 1500.

Usually you don’t have to reinstall an Amiga. Have you checked your Kicklayout?

Check the Roadshow manual; Try a larger TCP window size for example.

You can tweak the Roadshow settings to get better throughput.

@amiganuts

DDR is mentioned on page 4.

@amiganuts

Here's the Sam460cr manual (can't find a LE manual online): https://www.acube-systems.biz/download ... cr_EndUserManual_v1.0.pdf

But surely you got a paper manual included with the board?

@Hypex

But this is version 2. Still free though.

@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?

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

Quote:

My Sam460ex@1150 MHz have the same, with the -JU suffix.

-J is for PLCC.

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

@m3x

That's great news. Can you give us some more info regarding the new Uboot?

Don't forget to back the current Checkmate monitor kickstarter: https://www.kickstarter.com/projects/c ... -for-old-and-new-systems/
