I get a firmware formatted as a hex file. I import this file with checksum writting check box on. I can monitor the output power of the power stage using Fusion digital power designer, but I have to click turn on button. When I do connect the USB adaptor and the Fusion software, the output power is not automatically turnned on. What is the reason? Is it because the reset pin of UCD9248 is pulled high to 3.3V power without a capacitor to ground? I think this is not the reason because UCD9248 has internal power on reset function according to datasheet.
Thank you.
