I'm using GPIO0 as clock input. The oscillator is controlled with the RESET_N signal, so I dont accidentally starts the bootloader. Al signals seens to work. But the reset bit of the EMAC never get cleared (emac_ll_is_reset_done: dma_regs->dmabusmode.sw_rst)?
temp = LPC_ETHERNET->DMA_BUS_MODE; //always reads 0x00020101 in my case, the SWR bit position is always 1**further init to follow, but above should reset EMAC correctly, unless I'm missing something**The manual states "The reset operation is completed only when all the ...
Then Transmit DMA Engine restarts. but MACSTATUS stays 0x0000 0008, and 12th write to TX0HDP makes fifo full. And host dosn't receive ECHO back frame. --- I Correct my mistake remark. Editting TXEN can't clear FIFO. Should I make another thread? thankyou...

By postponing subsequent interrupts in a back-to- back condition, the software application or driver can get more work done in its ISR. The EWINTTCNT reset value can be adjusted from within the ISR according to current system load, or simply set to a fixed value that assures a maximum ...
