VIA VL805 USB 3.0 Controller w/ AT25F1024 SPI flash firmware update
In an effort to increase the performance of a generic 4 port PCI-E USB 3.0 adapter I bought on eBay, I went down the rabbit hole of flashing newer firmware on it.
After several failed attempts at using the VIA flash utility (see links below), I realized I had to determine which SPI flash was on my card. In my case it ended up being a AT25F1024, a chip that wasn't supported by the default flash utility. After referencing the chip's datasheet, I realized that it was very similar to the AT25F512 which was supported. I modified the AT25F512 configuration slightly and successfully used it to flash the card.
All in all I spent way too much time trying to update this $5 USB card.
In order to flash this yourself, add the following to SpiFlash.ini to support the AT25F1024 SPI flash:
