Here are the values shown by Ptune3 0.02 after a reset :

Thanks very much critor
By help of critor & Simon's document, I was able to revise it.
This is new beta version for fx-CG50/Graph 90+E updated.
http://pm.matrix.jp/Ptune3_002.zip

It is incomplete,if a bug is found I revise it.
I thank all of you.

-[OPTN]
--[F5] Only SDRAM memory speed Test

With Ptune3 0.02, now stops at 109.23MHz, just after the first artefacts have been shown on the screen :

--[F6] Auto check for memory speed Test(ROM & SDRAM)

Loops for some time, then freezes with a "roRw0: A10D0000" screen.
No capture, since the USB communication then gets interrupted.

Thanks very much for finding bug.

I'm sorry. I understood the cause.
I made mistake of double clock specifications from CG10.

-[OPTN]
--[F5] Only SDRAM Test
--[F6] Auto check for memory speed in each of wait.(ROM only)

The ROM test confirms that it works in CG10,
I think that it works this time.

Similar result :

Doesn't work.
I'm immediately getting something I had never seen, an animated system reboot dialog box.
The shown PC register is decreasing.

Hmm...
I'm sorry for not working well.
Something unknown seems to exist.
This problem wants to make reservation for a while.

However,
It was a crop that SDRAM works in more than 100M at default.

Thanks very much again.

Here is the Graph 90+E PCB :

(for the fx-CG50 PCB, just unsolder the exam LED beside the mini-USB port in the bottom right-hand corner, and switch the position of 1 port Q resistor at the right of the U101 chip)

I wanted to see this.

The CPU circumference look exactly the same.
SDRAM (M12L64164A-7TI) can drive 100MHz in CL2 or 143MHz in CL3. ( default CL2 )
The data sheet of the FLASH ROM (S99-50272) is not found, is the access time 90ns or 100ns?

It is to become clear if ROM memory speed test works,

I changed the ROM test program,
Even it works in CG20 and emulator,
but there is no confidence which works well in fx-CG50/Graph 90+E.

Here you are, ROM test alone :


And ROM test after a RAM test :

[sentaro21 Profile]

Oh! it worked!
Thanks very much for testing!!

As for ~v0.04, the memory test works in CG10/20.
From a result,it is a tendency same as early CG10/20.
Probably it is 100ns speed rank.
I think it is a result of the reduction in cost.

However, it is no problem if there is Ptune3.
