Not $0, but $O (O packet). The GDB protocol uses such packets to output text
non-related to GDB itself (e.g. your printf). The protocol also appends a
checksum to every packet, the #BB in your case.

It's waiting for an ack from the remote side of a GDB connection !!!!!
Try to set the option below in your ecos.ecc:
cdl_component CYGDBG_HAL_DIAG_TO_DEBUG_CHAN {
user_value 0
};
