AMD XHCI
The AMD XHCI controller in Hudson chip seems to be IP Core of Renesas uPD720200/200A. It looks the firmware consists of multi parts:
| Offset | Size in bytes | What | |
|---|---|---|---|
| 0x0000 | 2 | Signature 0x55aa | |
| 0x0002 | 2 | Offset to the BCD (type0?) | |
| 0x0004 | 2 | BCD size | |
| 0x0006 | 2 | Offset to Main FW (type1?) | |
| 0x0008 | 2 | Main FW size | |
| 0x000a | 2 | Offset to the ACD (type2?) | |
| 0x000c | 2 | Offset to the ACD |
| Offset | Size in bytes | What | |
|---|---|---|---|
| 0x0000 | 2 | Firmware version - 0x3032 means 3.0.3.2 | |
| 0x0002 | - | Firmware data, most likely V850 controller |
The firmware in blobs repository is 3.0.3.2, quite common version 3.0.3.4.0.8 found on the internet matches well 0xcf0 bytes. It is not know where the 0.8 subversion is stored.
