Bug in DM6437 UART hardware flow control in booting?

Hi,

We are trying to boot DM6437 from UART (mode=0x1000b, no hardware flow control).  Using genAIS tool, we tested a small test program and loaded it into DDR RAM.  It went through without CRC error (at least not reported by AIS).  Then we tested a slightly bigger program.  We constantly got "DATA CORRUPTED" message from DSP.

We suspect that the data corruption was caused by not enabling hardware flow control in UART.  So we enabled it by setting the boot mode 0x1110b.   To our surprise, we even could not receive any "BOOTME" from DSP.

Is there anything wrong in DM6437 bootloader? 

Can anyone give us any hint in loading large application code through AIS tool?

Thanks.

Alan
