Using the Service
Xmodem Service Methods
The following steps show how to initialize and use the Xmodem Service in an application:
pCtlTempo)
Variables definitions:
AT91S_RomBoot const *pAT91; // struct containing Openservice functions
AT91S_SBuffer
AT91S_SvcXmodem svcXmodem; // Xmodem service structure allocation
AT91S_Pipe
AT91S_CtlTempo
AT91PS_Buffer pXmBuffer; // Pointer on a buffer structure
AT91PS_SvcComm pSvcXmodem; // Pointer on a Media Structure
Initialisations
// Call Open methods:
pAT91 = AT91C_ROM_BOOT_ADDRESS;
// OpenCtlTempo on the system timer
pAT91->OpenCtlTempo(&ctlTempo, (void *) &(pAT91->SYSTIMER_DESC));
