It seems very likely that other versions are not compatible, so make it clear by including it in the machine type and name. Also update the documentation.

# K0501W V2.0
|
|
|
|
This board appears for example in the Davuaz Da-K6501W switch.
|
|
|
|
The general design of the board is similar to Hi-K0402WS V3.0.
|
|
However, there are several differences:
|
|
- One SFP port is replaced by a RTL8221B 2.5G PHY
|
|
- Only one LED is populated for the SFP port
|
|
- No mode switch and only one flash chip
|
|
- Older design using RTL8372 instead of RTL8372N (which also means different GPIO and LED configuration)
|
|
- Like earlier versions of the K0402W(S) board, there is no UART
|
|
|
|
All ports and LEDs are supported.
|
|
Installation is possible using a flash programmer.
|
|
The BoyaMicro 25Q16BSSIG flash chip is supported by flashprog with chip name "B.25D16AS/BY25Q16BS/BY25Q16ES".
