my mon51 cant work,
i using atmel86S8252
1 internal flash memory 8k, and 1 external static ram 32k (RD/ and PSEN/
signals connect to RD/ signal for the RAM)
Install.bat "0 3f 0"
Install.A51 "INT_ADR_OFF EQU 0H"
startup.A51 "CSEG AT 0"
In keil uversion option:
off-chip Xdata memory:

hi, HELp
ur mon51 can work?
can download user code to board and run ?
can i ask, the requirement say that the mon51.hex need 4k-5k space
but after me generate the hex file in window, and press properties, that file is 11k, any1 know why? i only hav 8k flash memory for store mon51.hex
what is mean by whr
can ask u 1 more question?
u hav any idea, how to test the external ram?
i wan to test, to see whether my wire connection correct or wrong.
keil uversion can test?
after connect all, when me press debug, the mon51 keep say cant find memory at address 5056h
movc command
thx a lot....for teaching me...
and 1 more thing, when press debuging at keil uversion, there say lost connection, cant connect to my board, i build the board my self,
i wan ask that, wat will cause my connection fail?
first is boundrate, and? ...
the rs232 hav 9 pin, we just...
mon51 wrong pc
''user's program is downloaded into by the IDE (uV3)'' ??
u mean download to external ram ??...
can u teach me the step? i read so long... still dunno how to download the user program code...

i wan ask that, how the mon51 work?
i save the mon51 program(mon51.hex) in microcontroller flash memory rom
than the user program code, should save at whr?
external ram? how to save the other .hex file to ram ?
MON51 must require both external ram and rom to work ?
i wan to build the circuit by my self, if need both ram and rom, it need so many wire...
any1 have the schematic diagram for MON51?
i m using microcontroller at86s8252..
and i wan ask that, the mon51 program is store at external rom?
