So I could not get any version of SigmaStudio to write to the EEPROM properly on Windows 10. Then it stopped communicating completely. I ran out of ideas at this point until I I thought about using Windows 7.
Luckily I have an old PC knocking around I was going to get rid of or re-purpose. Having found my spare copy of Windows 7 I installed this as a 32 bit version - although by accident having noticed I put the wrong CD in too late! Anyway, SigmaStudio 3.14/3.14.1 beta don't seem to work properly for the EEPROM writing but communicate fine with the DSP. However SigmaStudio 3.12 seems to work just fine; I can write to the DSP and write to the EEPROM. When I selected self boot from EEPROM on the PCB jumper it starts up just fine. Just have to remeber to have the jumper on the PCB shorted and "reset"/power cycle the DSP before writing to the EEPROM with I2C/SPI. You should also power up the DSP with the I2C/SPI USB adapter unplugged; and plug it in once powered. Also must remeber to set SigmaStudio to the correct EEPROM size. I am also not seeing any random errors in the PANIC CODE section anymore which is good as I figured that all the DSP boards are unlikely to have issues. So in short; Get Windows 7 (cheap keys on ebay?); install SigmaStudio 3.12; power up DSP board in the right mode; set up EEPROM size correctly and win! Awesome!
