printf with rs232

[kloppy]

1. this is not possible because if i delete the printf and compile the program, then it works.

2. i always check the configuration bits before i download the file. so this also can't be the problem

3.i am using picstart plus. in this case i program from adress 0 to 01ff. that should be enough... (i also check that everytime i download a hexfile)

i tried something else: here is the hexfile i read out of the programmed pic (the program that doesn't work):

I reformated your downloaded HEX file, to make it easier to read.
I found 2 or 3 anomalies. These are highlighted in bold, below.

At ROM address 0003, there is supposed to be a NOP, which is 0000.
But in your file it's 3FFF (The hex file formats this as FF3F).
So that location is not being programmed properly.

At ROM address 0034, there should be a GOTO statement.
Instead, it's 3FFF. That location is not being programmed.

Finally, there should be a SLEEP instruction (opcode = 0063)
at the end of the program. It's not there.

So where is the problem ? It could be in the programmer, except
that you're able to program Mark's and my Hex files OK.

Why don't you try using a different version of MPLAB ?
Try vs. 5.70.40. It's the last of the vs. 5.xx MPLABs.
I know it works. I use it. It can co-exist with vs. 6.xx
because they are installed in different folders, automatically.
Here's the link.

i downloaded, installed mplab 5.xx and compiled my program. it worked! so my compiler doesn't work with mplab ver 6.xx?!
do you think i can use mplab 6.xx with a new compiler version?


ps: the thing with the printf/interrupt is not the only thing that doesn't work. in another project i also had other problems. also those are solved with the old mplab version....
