1 console

es sind sogar 2 Serial console anschlüsse am ea6200 linksys router vorhanden einer davon 4 Pins von links nach rechts
VCC   # sollte nicht angeschlossen werden
TX # dieser ist mit dem gelben kabel verbunden und wird am UART anschluss  auf rx  nageschlossen
RX # und hier genau umgekehrt
GND # und masse sollte immer als erstes angeschlossen werden am besten sollte der

mittels Screen ,cu oder minicom etc 115200 8n1 sind die zu übergebeneden parameter

 

ausgeschalten sein damit mann auch den boot Prozess beobachten kann

bevor man herum  spielt sollte  man auf jeden fall die cfe.  sichern

 

zu beginn ist es möglich uboot params zu übegeben
mittels “ help“ in die console  eingegeben erhält man einen überblick aller verfügbaren befehle :
