I've run it on a Windows7 machine without any trouble.
But when I run in on a XP machine I get the attached error message.

If you are referring to the bootloader image, then I think you have it.
Address lines are 1-to-1.

Hi,
I'd like to test the DSP <=> FPGA bus interface by writing to a FPGA scratch address and then reading back the results to confirm success.
From the firmware, I see that there is dual-port dual RAM area that appears to exist for...

That circuit is not required for your design. It is a current measuring circuit in order to allow someone to measure the power consumed by the MityARM-335x module via I2C interface. You don't need it.

The datasheet for the MITYDSP-L138F shows Pin 53 as reserved, however the Industrial IO board uses it for SPI1_SCS0. Why does the datasheet show it as reserved?

Hi Mike,
Does that mean giving the analog input as as maximum produces 4095 value?
Shall i assume maximum ADC input voltage as 1.8V?
