Hello All,
This is my first post ever so I hope people respond!!
I"m using ProLoad V5.4 to program Atmel's 89S52 micro. I went to read the bits currently in one of our micro's and it never finishes reading it and the program hangs/crashes. It does say right before it crashes something to the effect that it only got to the first 8 bits or something to that effect. I apologize becuase I never wrote down in my notebook exactly what it said so now I'm going on memory.(ugh..stupid! me) I cannot read the bits from this particular micro. Although I got frustrated and blew new bits into it and now I can read the bits from it without an issue.
Does anyone know what it means when you can't read the bits from a microcontoller. The microcontroller which this is being used for is a military keyboard. The keyboad works fine under normal conditions but when I am doing a certain test it would fail.(keys stop coming out) To make a long story short I tried to read the code to see what was in it and that didn't work. So when I loaded the latest bits into it the keyboard now worked fine under the same test. Also you can read the bits from the micro as well. I did this to four more keyboards and had the exact same result. I'm perplexed. I'm thinking there was bad bits in there..but I'm not sure. Can anyone give me some insight as to what couple potentially be happneng.
Respones will be much appreciated.
Thanks all!!
