Hello, I read through the posts about the I2C EEPROM bootloader in the forum. I am still not clear how to do this. My purpose is as following:
(1) Download the firmware into the E2PROMs on the DVK board (2*128Kbytes E2PROMs).
(2) When I power on the board again, the firmware is loaded from the E2PROMs.
(3) Update the firmware in the E2PROMs later through the same USB connector.
In my understanding, I need to check the UsbI2cRegMode example as the first step. Once it works, I can insert these commands into my final program. Am I right? Could someone point me out what are the approximate steps I should do?
In the USB Control Center, when I choose Program->FX3->I2C E2PROM, the CYUSB3.sys for the CYUSB3.0 Driver is asked for. I link the original CYUSB3.sys to it, but it is invalid and the window appears again. What could I do about this?
Thank you very much
