Using FE kernel on FEup1 system.

Should running the 4.1FE kernel (on the CD) on a 4.1FEup1 system have any ill effects on the system?

I don't know what exactly the effect would be, there are probably bug fixes between the two versions, so you run the risk of being affected by those bugs.

Why did you want to?

The kernel version in the original FE was 53.70 whilst that in FE Update 1 was 53.89. There are too many differences to list.

As Andy asked, why would you want to use an older version?

The Up1 kernel causes a DSI error around 7FBExxxx when addressing Xena with the available tools. Near as I can tell it is around the AHI/device.audio at 7FBE2000.

I have tried the on CD kernel and it works. Don't know if it could cause any problems though.(?)

A bug report has been submitted and I know I should wait for a fix....... but the Ancient Enemy does not care about that.

Apart from bug fixes etc. in the kernel itself, there may also be other system components which require a certain version of the kernel to work at all.

So you risk having some function simply stopping to work at all.

In fact, if you really need to use the older kernel, I'd probably advise you to reinstall from the FE completely and stick with that instead of trying to mix and match.

If you do it on a separate boot partition, you can boot into that when you need to use the Xena stuff, and boot the normal system for anything else.

Best regards,

Niels

@NBache.

I second that.

I need to look into that.
I also need to look into the XTAG interface on the X5000.

It goes without saying that I have a lot of stuff that needs to get done.

I'm not hogging the fun stuff. I'll gladly share with anyone who wants to volunteer. :)

The XTAG on each machine simply "bit bangs" a couple pins on a CPLD.(?)
The format is simple, the code is well tested, only the actual hardware interface needs to be implemented on the X5.


And the X1 causing memory issues..?? I really could not even guess without digging deeper.

edit. I try to avoid making excuses.. But at the moment I am preparing to move, and the "move date" has been pushed up
a couple months. Eventually this should mean more free time and a better workspace, but right now it's all I can do to
keep up with my family and job responsibilities.
I'll keep trying.

Not a problem Lyle. As you know I already have a second installation of FE and playing with xena on that. Just a PITA doing so.

The JTAG is working on both kernels, FE and FEup1. It's the bus that causes problems on the up1 kernel. Unable to setup memory/address space in the PCI range.

Good luck with the move. I hope things go smooth.

P.S. I still haven't got after the vendor/device fix for the JTAG code. :(
