I used ADUC834 serial downloading for programming the code.After power on or reset pc can receive "adi 834 v23" and so on, then i can download hex file to the part through WSD.EXE.but it seems that the code isnot running after another reset.and whatever the PSEN pin'status is , pull down through 1k or pull up to vcc ,computer will get the part ID normally.
if i used verify code download... option , WSD will show error code 6..
crystal is 32.768k,
EA pin is pulled up to vcc (5v)
how can i fix this issue？
