Application requirements

Paulus can only handle application programs in binary format. The Intel-Hex-Format will be supported on request.

Paulus checks the received data by a CRC checksum. Therefore the application program has to have a header. This header can be generated with the tool paulus_cksum and contains the following information:

struct {
    UNSIGNED32 length;             /* length of the application program */
                                   /* in bytes */
    UNSIGNED16 crc;                /* crc of the application program */
    UNSIGNED16 applicationType;    /* reserved */
    void (*entry_point)(void);     /* application entry point */
} APPLICATION_HEADER_T;

Unused bytes in the application header are set on value 00h.
