Kintex-7 SATA PHY for M-Labs
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
[> Getting started
|
||||
------------------
|
||||
1. Obtain MiSoC and follow its "Quick start guide". Set the MSCDIR environment
|
||||
variable to the MiSoC directory.
|
||||
|
||||
2. Build design:
|
||||
make all
|
||||
|
||||
3. Load design:
|
||||
make load
|
||||
|
||||
4. Run test:
|
||||
make test
|
||||
|
||||
[> Cores :
|
||||
- UART2Wishbone bridge
|
||||
- SATA PHY
