#82267 - activating the boot loader Responding to: ???'s previous message |
Hi Erik
i am still unable to use the P89V52RD2BN. on P89C51RD2BN i have configured to activate boot loader by RTS and DTR. it is no longer possible now with "V" series. My board has 22.1184 crystal (Speed is a must that is why i changed to F124). i tried even with TV crystal 3.57mhz but no use. not able to connect to the device. when i tried to read the device signature it is reading. but programming is not possible. only one product has this device. soon that also i will change to F124. i have serached 8052.com and esacadamy and pilips but no use. at least once i have to program the device to use your "no touch" thanks for your simple concept i was using it on "C" series.
