 # M2 to ethernet board design on kicad 8
 
-This repository holds the hardware for M2 to ethernet board which has a intel I225 .
+This repository holds the hardware for M2 to ethernet board with a intel I225 controler with TSN feature.
 
 This board contains :
  * a I225 : KTI225IT S LNNL from intel
-	-advance feature : Time Sensitive Networking (TSN) –
- * an 8-pin connector to manage an Ethernet network (need specific cable adapter 
-														to connect Ethernet network)
+  – advance feature : Time Sensitive Networking (TSN) –
+ * a 8-pin connector (not RJ45 !) to connect an Ethernet cable
  * a PPS output on UFL connector
 
-Release 1 : not working
-Release 1 : fixed bugs
-	* fix signal inversion: PCIE_TX_N with PCIE_TX_P
-	* fix Intel reference I225 with advance feature to to handle TSN
-	* remove from design solder paste from connectors
-	* add solder paste on ethernet transformer pads
-	* remove gnd plane under ethernet transformer
-
-Release 2 : add ons	
-	* PCIE SM bus is now connected I225 (normally not necessary)
-	* The flash can be programmed via an external SPI programmer.

+Release 1 (July 2024) : first version (not working)
+
+Release 2 (Nov 2024) :
+ * fixed bugs
+   + fix signal inversion: PCIE_TX_N with PCIE_TX_P
+   + fix Intel reference I225 with advance feature to to handle TSN
+   + remove from design solder paste from connectors
+   + add solder paste on ethernet transformer pads
+   + remove gnd plane under ethernet transformer
+ * addons
+   + PCIE SM bus is now connected I225 (normally not necessary)
+   + The flash can be programmed via an external SPI programmer:
      - 4 resistors need to be removed to operate this programming
      - SPI bus connection and supply are on 1mm test point

-Release 2 published on 28.11.2024
-what remains to be done :
-* complete fonctionnel schematic rewiew
-* check bom (possibly reduce bom by grouping components)
-* generate fab files
