The max232 will generate 5 volt signal (transmit) and could damage serial pins of DSL502 CPU. Use a resistance divider to reduce 5 volt transmit of MAX232 to 3.3 volt. For receive MAX232 'understands' 3.3 signal also.
BTW I have already loaded my own file system, with 1MB of free space and thinking what to do next with... Its an excellent embedded Linux platform. The only hitch is that no data sheet is available for CPU.
Warm Regards,
