BlockStream and Timer question

[otinanai]

Hi there. We use the toro board.
We are experiencing two problems:
1) We have the following situation. The target application is sending buffers of 512 integers to the host

application through the pci interface using bus mastering.
In the host application we use the BlockStream class for the reception of data with BufferSize of 512 integers.
The problem is that when the target app sends n buffers, the host app receives n-1. Is there anyway to get the last buffer sent without the need to send any redundant data?

2) Our application demands the use of the timer that is used to drive the ADCs. This means that we need this timer to an output pin of the ChicoPlus module. We tried with timer0 and timer1 with no success.
But in fact, we have not understood yet what timer0/timer1 pins do and how they work. Are the timer0/timer1 (ie.pins 44 and 46 of module I (ChicoPlus)) connected to the (2 of the) 3 baseboard timers which are
controled through the ExtClock class of Pismo lib or are they connect to the timer0/timer1 output pins of the TMS320C6711 DSP processor?
Is there any way to get the DDS timer to an output pin of the ChicoPlus ?
Overall, how can we achive our goal in the first place ?

Thank you.
