Osmocom on Neo Freerunner can't finish loading

Hello everyone, I have compiled osmocon binary for Neo Freerunner (after receiving explanations from the list - thanks Alex!). It worked... during some time. Now the loading does not finish: # ./osmocon -i 13 -m romload -p /dev/ttySAC0 layer1.highram.bin Sending Calypso romloader beacon... Sending Calypso romloader beacon... ... Received parameter ack from phone, starting download ... Preparing block 44, block checksum is 0x8c handle_write_block(): 1024 bytes (1024/1024) handle_write_block(): Block 44 finished Received block ack from phone Preparing block 45, block checksum is 0x97 handle_write_block(): 1024 bytes (1024/1024) handle_write_block(): Block 45 finished ...and it stalls at this point. Altogether, there were 47 blocks, if I remember right (so the feeling is that "I'm so close to it" :-))). The phone is otherwise accessible (via ssh). Any highlights on what could go wrong? I can't remember having "done" anything at all to the phone... Dave.
