Hi. OK, we hunted this down a bit. It is a dynamic memory allocation problem. In CoapUdpServerP we save the CoAP transaction ID in coap_save_splitphase(), in order to do so we are allocating a queue node and a pdu. The last one fails on a Z1 with printf enabled.
If printf is disabled in the Makefile, CoapBlip works for me on Z1. # CFLAGS += -DNEW_PRINTF_SEMANTICS -DPRINTFUART_ENABLED Trying to debug it with printf, makes it fail.... ATM you have to be careful which resources and options you enable (not only on Z1, but especially on Z1).
