Are you using an ‘on the nose’ crystal such as It is internally pulled up. Dec 248: Future, I will test another frequency.

The time now is I have even experienced failures sometimes at baud with no high speed comms enabled. I don’t promise the data is exactly corrective.

You can also roll out your own bootloader, which might then be independent on UART; nevertheless this is not an easy task for a novice.

To enter the programming mode again, different chips use different methods, read the datasheet of your particular chip. Please login or register.

Where to buy mp3 chips in US? ModelSim – How to force a struct type written in SystemVerilog? Synthesized tuning, Part 2: Therefore Flash Magic only uses timer 2 reload values that are lower than a certain threshold value that I have found results in reliable bootloader operation.

I’ve tried using Flash Magic high speed comms with x12 clock checked and selected initially either or baud, and both failed part way through programming with an “unable to communicate” message box. In addition, I modified my own ISP programming applet to set the baud rate to using the direct load baud rate function timer 2 reload value 0xffee after auto bauding initially at I can see the same behavior.

But, I will continue to test in future. If you don’t understand the table.

Choosing IC with EN signal 1. Several timing critical programs such as JTAG programmers and Parallel programmers work excellent under ’98 and very poorly under any downgrades from that. Again, the failure is always part way through the hex file download in the programming cycle.
