Other Parts Discussed in Thread: USB2ANY, PGA900

How can I load .hex file in PGA900, using I2C USB2ANY interface? I would like to receive scheme. Before that, we used the SPI interface, the program has successfully loaded. Unfortunately, the SPI interface is dead, so I would like to use I2C. We tried to connect pins SDA, SCL, GND, but this is not enough.
Help me to solve this.

Yura,

What are your jumper configurations for the EVM? You should have no problem writing over I2C if you use the Voltage Mode jumper configurations found in the EVM User's Guide.

I have no problem with PGA900EVM boot code through I2C. I have a problem downloading the code to my target board through I2C.

Yura,

SDA, SCL , and GND should be all you need. Are you tied directly to the USB2ANY, or are you tied to the test points found on EVM?

It looks like I figured out what the problem was. SDA, SCL, GND must be connected and the CSN should be pull to GND via a resistor. I have established a link between USB2any and my board.
