STM32MP1 ethernet RMII

[Jaroslav Buchta]

Uz me nic nenapada, tak se zeptam...

GDB se docela bez problemu pres OpenOCD pripoji a nejak funguje, symboly 
nacteny, prerusit program jde (na zacatku mam nekonecnou smycku) ale 
proc sakra nema pristup do pameti???

Program received signal SIGINT, Interrupt.
