Connect ME data abort using TCP sockets

0 votes
I am working with a Connect ME unit:
Firmware Version: 2.8.2.3 (Version 82001116_K4 09/22/2011)
Boot Version: 0.0.0.1 (release_82000866_C)
POST Version: 1.1.3 (release_82000867_H)

communicating with an embedded board by means of "TCP sockets". When the packet length is somehow short (i.e. 30 chars) the communication is goot. When the answering serial device needs to respond a bigger packet (about 70 chars), an exception occurs. I have tried at lower speeds (down to 9600), and also tweaking the "Send data only under any of the following conditions" to 10mS and 512 bytes. I also tried the firmware version 82000856_F6. Here follows the exception:

DATA ABORT
screen of death data:
r0:0x022022F0

r12:0x00000000
sp:0x0020FF9C
lr:0x00000B3A <-- code addr (-2/-4) that caused abort

Extra User land regs:
sp:0x0020FD70
lr:0x00000AC3 <-- code addr (-2/-4) called just before abort

Can anybody help?
