Hello Friends,
I've write a program in keil (in C language) and build a project.
--> options are set to Freq. = 11.0592 MHz, Use on chip ROM, Create Hex File.
Nothing else I've changed in option for target. and Now I've a hex file of the project, which I am trying to
program in NXP p89v51rd2bn using Flash Magic 6.01.2547 .
As I haven't serial port in my PC, I've purchase Serial to USB cable BF-810 (By BAFO TECHNOLOGIES).
In Flash Magic I've set a select device option properly to my mc, and have set baud rate to 9600 (also have tried by varying it)
Interface: None (ISP) and haven't select to erase option. then I've make a tick on Veryfying after programming.
When I press start It asks me to reset my device in ISP mode.
Now I've press reset button of my controller kit but there is no change.(Reset button have proporly connected to Vcc and GND. When I press it; it holds 5 V otherwise 0 V ).
I've check why it actually asking for reset, then I found that It sends Uppercase 'U' character and willing to receive back through cable, So at the time when Flash Magic asking me to reset my device I manually short the TXD and RXD (P3.0 and p3.1) of controller to transmit the same 'U' back.
And finally the dialogue box which was asking me reset gets dissapear... And now after 60-80 seconds I got a message " UNABLE TO CONNECT (RECEIVE/TRANSMIT).
Can Anyone solve the problem please.
Here the cable is ok because the 'U' is get received by PC as I joint TXD and RXD, so cable can't be faulty.
the controller kit has all proper connections. and also the path form RS-232 port to TXD, RXD pins are also ok because
as I joint the TXD and RXD the message gets dissapear instantly !
so what should be the problem please reply.
[ BF-810 is compatible for Flash Magic I've got this from this link : **broken link removed**
I've check EVERYTHING listed here : Failed To Autobaud

Thanks
