| Awesome! Have you discovered what chpis/cpu it has? Also wonder if the sampler version will have different hardware. Or newer e2 models with beefed up specs. |

Yeah, I'd say THAT'S done for your Warranty!!
Thanks for stripping it back, I'm impressed by how tidy it all looks in there, I used to have a job making mobile phones and some of Those boards looked like the Dogs Dinner!

All of the IC's on the control board and main board are in the photos. The control board has an ARM Cortex-M3 (MB9AF141LA) with 64KB with integrated flash memory. Midi-in goes to one of the serial data pins, and it's gotta be running in UART mode. there are de-populated jumper header spots on the main board, i'm guessing read/write protect and debug interface is taken out for production versions.

I wonder for what IC7, J2 and J3 is good for  |

Thanks and sorry about your warranty. 
Looking at the TI AMI1802B on the CPU board, it seems consistent with the strings previously found in the firmware:

Speaking of which, you can gran a few hints from the 1.03 firmware posted at korg's japan, when viewed in a hex editor :
| Quote: | ././src/Dsp/DspIf.cpp...
././src/MCU/Component/AM180xMMSDCardController.cpp..
././src/MCU/Component/AM180xSpi.cpp.

././src/usb/cusbdc.cpp..
././src/usb/cusbdrv.cpp.
././src/usb/cusbdc.h....
././src/usb/cusbreq.cpp. |
Looks like it is ARM9 (TI Calixto AM180x) based, maybe with the associated DSP
|
I wonder if the Analog Device ADSP-BF523 BLACKFIN is the main DSP, or just here for the MFX/Kaoss Pad or other non audio purposes.

If you open the os update file with any hex editor you'll find some more or less interesting ASCII strings inside the binary code. |

Okay, I've been looking at your pictures again, and - correct me if I'm wrong - I think it should read like this :
Direct links to your pictures @imgur added when possible.
Any embedded systems dev to educate us, given what we know of the e2 idiosyncrasies from the early adopters point of view ?
Anyway, hope this helps.

| Thanks for sorting out the ICs! Seems to me this device has more than enough muscle power to do pretty much anything we want. The crux lies with the coders at Korg. They should've taken enough time to properly optimise and bug test the firmware before releasing it. Getting a good optimised firmware that takes full advantage of all the HW takes time. |

I have a DediProg SF600+ SPI "in system programmer", which can read and write to IC8 (MX25L12835F) on the KLM-3314 board, and I also have the adapter (Pomona SOIC-Clip Model 5250) to clip onto the IC, without having to remove it from the board.
I initially tried using the adapter in the default pinout, but realized later that the RESET pin coming from the programmer was not connected to the RESET pin going to the IC, so I modified the adapter to account for this. All of the other pins are connected correctly.
However, I was never able to detect the EEPROM IC correctly, it was always acting as if the clip wasn't attached at all. I use this tool all the time at work, and this should have worked...
Before anyone asks, I did have the voltage set correctly, and I even went in and manually set it the config to the Macronix MX25L12835F IC, but it still was never able to detect. Any ideas? |
