Input port and input output port declaration in top module 2. The timeout error can mean communication is not established with the microcontroller in bootloader mode. The time now is Similar Threads microcontroller related 1.
Dec 242: The PSEN pin needs to be grounded at reset to enter bootloader mode.
In Flip, the RS setup utility has to be run each time the microcontroller is reset into bootloader mode, before the chip is programmed, or it will give the timeout error.

Heat sinks, Part 2: In the RS setup, the maximum baud rate I can use isso lower baud rates can be tried to see what works. PNP transistor not working 2. To run the program after it is loaded, PSEN is floating or high at reset.
I am using RS Connection But press only when the post helped you If yes then how can u programming this IC? Hierarchical block is unconnected 3. R u using any programmer or using ISP?
Part and Ddatasheet Search. How reliable is it? If none of the above help, you might want to post the schematic of the setup you are using.
That also creates this kind of errors. Last edited by FenTrac; 24th December at AF modulator in Transmitter what is the A? How can the power consumption for computing be reduced for energy harvesting? Of course, the right device has to have been selected under the device tab. I can also do RS Communication and my program can send data and i can receive that data on hyperterminal
