Hello,
I am using USBi with SigmaStudio v4.7. I also have ADAU1701 mini eval board, and my own target board with ADAU1701, EEPROM socket and USBi interface header.
The discription of the issue is as follows:
If I plug the programmer with the target board connected or the eval board connected, then, all the status LEDs on the USBi remain lit and the hardware configuration tab in the signaStudio remains red.
If I plug the USBi programmer into the USB port of my PC (Windows 10) without the target board, then the USB status in the hardware configuration tab of SigmaStudio turns green. All the status LEDs on the USBi light up briefly and then only the power LED and I2C LED remain lit. The SPI LED and the blue LED turn OFF
If I plug the USBi programmer into the USB port of my PC without the target board, with the USB status in the hardware configuration tab of SigmaStudio green and only the power LED and I2C LED remain lit and then connect the ADAU1701 eval board to the USBi, then two red LEDs next to the push switches, one red LED near the 3.5mm audio connector and one green LED to the right of it all light up.
In any case, I am unable to program the EEPROM either on the target board or on the eval board. The SigmaStudio flashes USB communication error message.
Kindly advice.
Thanks!
