STM32F767 ethernet rychlost

[Jaroslav Buchta]

Zdravim,

mam problem s implementaci subj, pouziva HAL, vse nakonfigurovano 
pokusne v prazdnem projektu.

Aplikace pouze odesila data po pripojeni klienta, prenosova rychlost je 
zoufala, asi 1kB/s.... Netusi nekdo, v cem muze byt problem? Asi malo 
nejakych bufferu? Ale experimenty nikam nevedly.

Pres switch to chodi asi 3x rychleji nez primo pripojene k PC, asi to 
servisni komunikace nejak zahlti? Nebo delam neco spatne?

Sledovana komunikace ale vypada plynula bez komplikaci, .123 je PC, .9 
STM, viz priloha
