| I know exactly what you mean. Here's the function to copy the bootloader reset vector and application reset vector from an incoming file into global variables
if(uSourceAddr.Val32 == 0) ... |

| Could this be also a compiler bug or problems with jumps? I had a bit weird behaviour going on, not sure that it was i.e. when I increased the stack from 256 bytes to 512 bytes, the top RAM usage jump ... | |

| I've used global static variables to store both reset vectors, i.e.
static ureg32 uBootResetVec0; // bootloader reset vector value 0 (at address 0x000000) static u ... |

| The ORG is a good point, thanks. I must have thought compiler would make sure 0x203 would not be used but I was wrong.
The way the bootloader re-maps the reset vector is: - the hex file is modified ... |

| Hi,
I'm working on the bootloader for PIC24HJ128. The compiler version I have is PCD 4.132. The bootloader reset vector is at 0x0000, the application reset vector is mapped by the bootloader (not ... |

| Has anybody been lucky with getting MD5 code (from RFC) to work on PIC24 and PCD (v. 4.126d)? I've tried the RFC code but even for empty text the output is incorrect. I've also tried writing the wikip ... | |

| I think I posted most of these points apart from a sample code. Since it's quite a big code at the moment it was hard to find that specific thing. Nevertheless, it took me all day chopping it down and ... | |

| Hi,
I'm using PIC24HJ with a software UART (can't use any hardware - due to spec). The fprintf sends hex sometimes correctly and sometimes it sends the hex and lots of zeros 289a0000000000... (a ... |
