I am using ARMWSD.EXE to download HEX into ADUC7029,but I do not know how to connect aduc7029's SPM0 AND SPM1 to RS232 of PC
ADuC7029 uses 3.3V logic levels while RS232 +-15V so you cannot connect them directly.
One of the options is to use an FTDI cable, that converts 3.3V UART to USB. The USB shows up on a PC like a virtual com port, The same as an RS232 port.
Otherwise ADI does sell a cable which converts 3.3V logic (4 pin connector) to RS232 is you do have a PC with RS232 and you need to use that interface. Have a look for it on the evaluation board page.
The cable as far as I recall also is included in the quick start plus evaluation kits, but a lot of people don't use them nowadays as it's hard to find PCs with RS232 ports.
