[Developers: The Corsair Link USB protocol!]

I looked at the IDE download mostly out of curiousity (I'm not going to teach myself assembly for this). I haven't actually tried to install it, but it doesn't look very free to me. The only download available is the professional evaluation - which gives me until June 10. - after giving a ridiculous amount of information during registration. Is it license.dat from the page you linked to that makes it a free version, or is "free" simply the name (from freescale)?

 

You are correct, I had the wrong link there. The non-time-limited version is the evaluation version. It does have limits on code size (64kB), but the MCU only has 16kB of flash so it doesn't matter.

 

And yes, they unfortunately do want to collect all sorts of information from you, but I'm sure you can find a way to tell them what they want to hear.

Thank you for the pointers. Is http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=S08MP the correct link for all the other information. I plan to have a look over the next few days, but at the moment I am looking into adding H100iGTX/H80iGT support to SIV. Does anyone know if the CL Mini uses the same chip? I suspect not as the I2C register layout is very different.

 

I have cropped and rotated the attached image so the header is now top right.

 

That looks like the correct link. You'll probably also want the free IDE (Evalutaion) for firmware development. (Thanks Nadar for the correction).

 

The IDE includes a disassembler at C:\Freescale\CW MCU v10.4\MCU\prog\decoder.exe, so you can turn the .s19 files back into assembly.

 

 

EDIT: fixed link to IDE.

Finding out what MCU is inside would be great if we wanted to develop our own firmware. Even if we don't make any custom firmware, we can still help out red-ray by checking the manufacturer's app notes for the upload procedure.

Also, despite all the firmware images being SREC, there might be different MCU's on each device. Has anyone opened up any other devices to find out? I imagine some people have opened the Commander nodes at least, since it would have low risk of causing any damage, and they look like they were designed for experimentation from the start.

 

The cooling node uses a Freescale MC9S08MP16 processor.

Here is the cooling node with a 6-pin Freescale BDM programming header in the top left corner.

 

I believe the H100 also uses the same MCU, but I can't find any photos from when I took mine apart to confirm.
