Проблема с TSE в NIOS, TSEMAC SW reset bit never cleared! Опции

[toly1985]

Здравствуйте!

Есть плата с CYCIII + 2 PHY KSZ9021GQ.

Во время отладки программы web_server под NIOS выходит ошибка "TSEMAC SW reset bit never cleared!".
И соответсвенно не запускаеться web-server.

Кто сталкивался с подобной ошибкой - в чем причина?

на модуль TSE заходят данные. По каким причинам он не будет эти данные выдавать их в FIFO ?
Может нужно "как-то правильно" сконфигурировать TSE?

Command_Config Register у TSE.

SW_RESET
Software reset. Set this bit to 1 to trigger a software reset. The MAC
function clears this bit when it completes the software reset sequence.
When reset is triggered, the MAC function completes the current
transmission or reception, and subsequently disables the transmit and
receive logic, flushes the receive FIFO buffer, and resets the statistics
counters.

По каким причинам этот бит не очищается?
