Hi Andy,
                     Before programming with topwin 1 or two times I programmed 89v51rd2 fn with Flash magic at that time it was working fine.and Just for analyze I connected hyper terminal  and i could get U replay back from MC.

This time also am doing the same only .If am not invoking it correctly then anyway flash magic tool could invoke It and detect the processor rgt ?.but that is not happening

and wen i install  P89V51RD2_V05_UPD_ISP.hex and try to invoke it is printing the message?.

If  you can tell the starting address of block 1 then i ll burn the code in that address

or if anyone having a red copy of hex file plz send across it i ll try with that 

thanks

P89V51Rx2/P89LV51Rx2 / How to install new bootloader...
December 09, 2009, 03:22:42 AM
Hi i am doing programming with P89v51rd2 micro controllers.I have a usb programmer[TOP2049] using that i dumped some example codes to my p89v51rd2 mc [i have 3 units] and all are working fine [i tried LCD example,uart,i2c]. Now am thinking of working with ISP.here the problem comes, I connected the IC to the Hyper-terminal and checked for the U .It is not coming.I checked uart and development board It  is working fine .So only reason what i am finding that My bootloader may get erased when i used the TOP2049 programmer.

I went to website and downloaded the P89c51 bootloader,
http://www.standardics.nxp.com/support/documents/microcontrollers/all/?scope=P89V51RD2&sort=date
and Installed P89V51RD2_BL_V05.hex. after that also am not getting the U on hyperterminal

Now i suspect  i  burned the code in wrong block,which is the starting address for block1 ??

my  programmer is showing two blocks code[0000-7fff] data[1000-11fff] [check the image topwin.bmp]. I burned P89V51RD2_BL_V05.hex  to both memory location but then also it is not generating U

what will be the problem what is the configuration i have to keep
the configuration which i used now is shown in picture tpotwin .jpg
If i am burning the hex file P89V51RD2_V05_UPD_ISP.hex in the First block starting from 0000 then i ll get the message
