CT60e does not boot in 060-mode

[paul92706]

Ok, progress! I very carefully removed my beloved Afterburner from my first Falcon and tested the CT there. It boots, but crashes while copying TOS to RAM. I guess mikro is right and that my CL3 RAM is not suitable.

Next step was to debug my other Falcon. Turns out the buffer patch was the problem, there was no clock to the expansion port! No wonder the CT would not boot... I wish I could blame someone else for this but it's entirely my own fault, I did not replace R216 when I removed the BlowUp FX and restored the original Atari clockpatch.

And what's better - one of my CL3 DIMMs are actually working! I see the desktop!

ahh! you must completly restore to original specs!!

Glad to hear that, Jo! Feeling like this one is unbeatable, isn't it. ;-)

Great!

I got a CPU for my CT60e today, but unfortunately it will not boot in 060-mode. The Videl just outputs a black image and some weird sync signals, and there's no other sign of life either. Everything works normally in 030-mode. So far I've tried the following without success:

* Two different RAM modules. Both are 512Mb PC133 CL3 with a total of 16 chips, 8 on each side. One with Samsung K4S560832E-C75 chips, one with Micron 48LC32M8A2 chips.
* Two different PSU's. A PicoPSU and a normal ATX.
* Two differenc CPU's. The Rev 6 I received today (which works in the seller's CT60) and the Rev 1 from my Milan (which I know works as the Milan is still working after I put the CPU back).
* Tried to reset a few times after power-on.
* Tried to power on in 030-mode, switch to 060 and reset.
* Tried to power on with ALT key pressed.
* Tried to power on with the "Rescue" jumper set.

The CPU gets lukewarm, around 30-35C, so something is happening.

I've also tried to run the flash-tool from willy's site in 030-mode, it says that no CT60 is found.

Any suggestions on how to proceed from here?

Hi joska i apologize to bring up an old thread but i am having same issue with my CT60, using the Flash tool in 030 mode i am getting message “CT60 Not found” i think you mentioned you had wrong sdram cl3 and abad clock output? Is this accurate?

The real problem was a faulty clockpatch in my Falcon. There was no clock on the expansion port.

Thanks for your answer, question to you, do you know where the /BG signal on expansion is coming from!? I asume MPU pin 16 is this correct?

I can't say from the top of my head. Check schematics and servicemanual on https://www.dev-docs.org/docs/

Ugh i have done about everything, and still i get that “CT60 Not found” message upon flashing in 030 mode. I read on. Rodolphe’s webpage we are suppose to remove the clock patch and install a 47ohm terminator. I really don’t want to ripp off the clock patch, if it is not the problem!

Quick question Jo are you able to now access the CT60 with flash060 in 030 mode after fixing your problem? Or are you still getting the CT60 not found message?
