I’m designing our board with Xavier NX module. On the devkit, the HUB chip is a Realtek RTS5489-GR ( the public one is RTS5420?). But the doc about the chip is not easily to get for me. So, my goal is to use a more publicly available one, such those from TI, and use the devkit’s image without much driver coding. I have several questions:
- I’ve never use Realtek’s USB hub chip. But in TI’s chips, they states they need no special driver to run with OS, all should be handled by USB protocol. Though their chips have external configuration interfaces, they may be bypassed, and the default configuration should work. So, may the guys from Nvidia confirm me that a chip from TI with no special driver needed will work with Xavier’s image?
- And for the Realtek one, are there any special driver needed to run the chip? As there are at least two external interfaces to the chip, one flash and one I2C bus. What the driver/chip do to these two interfaces? What content is stored in the flash?
