firmware_buffer
is a large enough buffer to hold the entire firmware.
Once a SCSI transfer has begun, the next SCSI transfer must wait until
the firmware from the previous transfer is successfully moved to the
serial EEPROM by using the TWS bus. Actual code should check for the
BUSY or SUCCESS check conditions. If the status is BUSY, the code
should wait until a check condition of SUCCESS or FAILURE is returned
and the sense data should be read to verify that the command to update
the structure was successful. Finally, the command to issue a REBOOT
requires no additional validation, as it is purely a SCSI command.
The pseudo-code is presented below:
char send_buffer[1025]; //Generic buffer to hold data to
send.
dataptr = buffer;
status = GOOD;
bytes_left = firmware_size; //Initialize to size of firmware
image
while (firmware_size > 0)
{
//While there is data left and previous write succeeded,
// issue the next write buffer command.
bytesToSend = bytes_left;
if (bytesToSend > 1024)
bytesToSend = 1024; // Reset maximum transfer to 1KB
//Copy bytes from dataptr to send_buffer,
//compute checksum and append
Copy(bytesToSend, dataptr, send_buffer);
checksum_byte = Compute_Checksum(bytesToSend, dataptr);
send_buffer[bytesToSend +1] = checksum_byte;
if ((status = SCSI_Write_Buffer(4, bytesToSend+1,
send_pointer)) != GOOD)
{
Request_Sense();
return;
}
//Error on the SCSI Transfer
if ((status = SCSI_Write_Buffer(4, 0xFF0000, send_pointer)) != GOOD)
{
Request_Sense();
//Error on the SCSI Transfer
return;
}
Request_Sense();
//Issue a request sense -if not
