Hi,
> Ah yes, if that works, we should. That bit is from the Linux BSP, isn't it?
Yes, it's from Linux BSP code only. Hope following is fine.
if ( reg & STATUS_TXFIFO_EMP )
return TX_FIFO_SIZE;
else if ( reg & STAT_TX_FIFO_HFL )
return TX_FIFO_SIZE / 2;
else if ( !(reg & STAT_TX_FIFO_FUL) )
return 1;
return 0;
Thanks
-Amit
