Hello!
I am trying to design a prototype device that will use the CYW20719 chip. So far I have been using the eval board, but for this prototype I would like to use just the chip. What components are necessary for to be able to program and debug the chip while it is not in the eval board?
I would like to be able to program and debug the device from a USB cable, so I know I need somehow wire this to the HCI UART lines of the chip. I would also like this device to be battery powered. Are there any pitfalls I should watch out for?
Thank you,
Nicholas

Hi Nicholas,
Apart form HCI UART pins, you may have to look for the Crystal and Antenna connections. Design your power supply as per the specifications given in datasheet for VBAT and VDDIO.
Also if you are going to reprogram the chip, its better to have recovery button on board.
Please refer the CYW20719 schematics and platform files to reconfigure the pins you want to use.
