New eFlasher available

[tjaoz]

@BR

Yes, only when the boott jumper is on. The only thing I've flashed is what the installation script asks if you want flashed,
the OS Rom Update.

Try to program FlashROM from Shell. First do this: eFlasher ROMUPDATE. Then switch ON the eFlash booting. Is it working OK?

The distance between the two accesses is short, yes, but the distance to the next longword-access is the same as between two single word accesses, so the gain is minimal, and the gain is the same on *all* Zorro II implementations.

You may wrongly understood what your logic analyzer showed or you do not understand what we are talking about here.

You can see from this image that reading of the longword from PIC in this backplane lasts for 8 clock cycles. If, as you say, the break from the end of longword reading to starting the next reading is standard, that is one clock cycle, it means that readings of longwords start every 9 clock cycles. The speed of reading the PIC card in this Zorro II backplane is:

4 (bytes) * 7.14 MHz / 9 cycles = 3.17 MB/s

3.17 MB/s is rather higher from 2.8 MB/s, which Hodges thinks is the maximum possible Zorro II reading speed...

Now let's go for some content: Elbox claims that executing code is possible without copying into memory. Sorry guys, the Amiga roms *always* copy the Zorro-roms into ram, and execute it there.

You misunderstood that text to which you are referring. Read it again and read my post to Hodges on it.

Double-standard: Mediator1200 uses banking, and that's OK.

Mediator 1200 must use banking due to the design of turbo cards for A1200. If A1200 turbo cards had all 32 address lines led to the CPU connector, then there will be no banking in Mediator 1200. Fortunately, the window is quite large, 8MB, so its switching in normal operations is quite rare.

My Kickflash uses banking, and that's bad. I wonder why.

The window in Kicklash is very small (16kB), but I think it does not matter. The BASIC thing is that both Flash chips are in Kickflash connected to the same 8 data lines. This reduces the maximum speed of reading from Kickflash to 1.4 MB/s.

Speed: Kickflash has 1MB, and copying that to memory takes a little over half a second. It saves you a reboot, meaning on some systems it saves a good 40 seconds.

Could you specify the config in which Kickflash saves 40 s?

Ah... Rat's back...

You may wrongly understood what your logic analyzer showed or you do not understand what we are talking about here.

Funny you are. Ever worked with a logic analyzer? Ever built any hardware yourself?
No, I'd guess. And now you start pissing at somebody's foot who is in hardware business for years now.

BTW, if talking about bandwith... busses usually are shared, so you won't be able to do bus hogging for too long, which means that you normally get about 80% of bus bandwidth in ideal cases.

Mediator 1200 must use banking due to the design of turbo cards for A1200.

Even if there were 32 address lines, you would have to do banking, as PCI address space itself is 4GB, and 32 address lines are exactly 4GB.
The Amiga itself needs some of this address space.
AFAIK, the Mediator is mapped into the system as Zorro card, and the size of Zorro cards is limited again (Zorro II: 8MB, Zorro III: 1GB).

Ah... Rat again...

Algor FlashROM is available ONLY in the processor data space?

Another proof of your knowledge... how do you access memory without address lines ? Good god...

If any company tried influence me, well, Michael Boehmer from E3B tried to frighten me in his private email to make me change my words on Algor. I do not want to listen to him. I always try to base my statements on verifiable facts.

Well... nice try. But unfortunately you always fail with your attempts to give any proofs for your statements.

What you refer about was simple (you may look in the corresponding mail): if you think you found a mistake on a web page, contact the webmaster of the site. You didn't. You started spreading public accusations on mailing lists.

Are you planning an attack? Bombing them or hitting a plane in their building?

I don't think such dramatic action is foreseen. And I don't think it is necessary  :-) .

What I could think here is that with Poland joining the European Community same laws apply to all of us. Laws regulating unfair competition, dealing with advertisements and warranty issues.
Some cheated customers might just be enough.

Are you from Al-Qaida?

Are you from Al-Buggs  :lol: ?

 ROFL... Now I`ve read it all, Tjaoz telling Jens that he doesn`t know what he`s talking about..:lol:

@Tjaoz,
 Why do you flame others for not understanding your replies, when you clearly don`t understand them?

 

This is a HARDWARE feature that eFlash 4000 FlashROM memory area is available in the processor data and program space. This allows preparation of such programs/procedures, which may be executed directly in the Flash memory

 Executed directly in the flash memory?
 That`s dangerous. As others have pointed out, the majority of programs **MUST** be loaded into RAM before execution.
 What would happen if the program contained a BSS hunk (and there`s at least one in the 3.9 RomUpdate that does) and was executed directly in flash?
 The program stored after it in flash would get overwritten and corrupted.
 
 So either you`re wrong and don`t understand how programs are loaded an run, or you`re right but the eFlash is likely to keep corrupting it`s contents.

 BTW, care to explain what you mean by "processor data and program space"
