Hi everybody. I would like to ask you for advice of checking conditions for next transmition start ability. I tried to catch the GMAC_ISR_TCOMP in IRQ handler or check GMAC_TSR_TXGO, tried to wait for USED bit transition to log.1 in Tx descriptors, but nothing seems to be sufficient and I must insert some delay before next transmision.
Strange thinks occures to when I worked only with one Tx buffer. Every transmision was done twice and ended with GMAC_ISR_TXUBR set.
Can anybody help me please?
I'm using SAM4E16C with LAN8710a
