[etherlab-users] "Invalid mailbox configuration", how to configure?

[Stefan Löfgren]

More info on that seg-fault:

The number of SMs seems to be ok.
The segmentation fault is in here somewhere (I don't know exactly where yet):

Row 833-848 (approx. in file "master/slave.c")

            list_for_each_entry(pdo, &sync->mapping.pdos, list) {
                buf += sprintf(buf, "    %s 0x%04X \"%s\"\n",
                        pdo->dir == EC_DIR_OUTPUT ? "RxPdo" : "TxPdo",
                        pdo->index, pdo->name ? pdo->name : "???");

                list_for_each_entry(pdo_entry, &pdo->entries, list) {
                    buf += sprintf(buf,
                            "      0x%04X:%X \"%s\", %u bit\n",
                            pdo_entry->index, pdo_entry->subindex,
                            pdo_entry->name ? pdo_entry->name : "???",
                            pdo_entry->bit_length);

/S
