First of all, thanks for interesting.
I'm developing a bootloader therefore I write each line of .hex file.
I don't know what address I'll write, simply, I read every line, take address, take byte and write that.
Can I overwrite ALL firmware, or not?
If I want to store only 1 OPCODE, for example:
I would write 000100 at address 000000.
Can I, or not?

I am trying to write in PM. I found this .asm library in AN1094 (Bootloader UART)
_LoadAddr: ;W0=NVMADRU,W1=NVMADR - no return values
mov W0,NVMADRU
mov W1,NVMADR...
Hi guys,
I need to flash program memory, actually I use this function for write/read EEPROM:
Write And Read:
unsigned short Eeprom_ReadWord(unsigned short addressHi, unsigned short pushAddress) {
unsigned short ushResult;
register int eedata_addr;
register int eedata_val...
Hi, I'm trying to write a .hex file on a dspic 30f5013 using a flashing program created on my own , this is a line of the file:
:10021000050007000c000700e204020000000000d7
I studied the structure of hex files but I still have a question for you. I underlined the first,second,third and fourth...
Hi,
I'm using ICD3 to flash my firmware in dspic30f5013 but now I'm coding a bootloader that allows me to load the built-firmware (.hex) via canbus through my IDE developed in C#.
I must write .hex file only in Program memory ???
Thanks.
Thank you very much!
If I type this code:
//Read and write 1
Eeprom_WriteWord(&ushEepromData[0], 0x0023);
uchValue = Eeprom_ReadWord(&ushEepromData[0]);
//Read and write 2
Eeprom_WriteWord(&ushEepromData[1], 0x1111);
uchValue2 = Eeprom_ReadWord(&ushEepromData[1]);
The first time, the program...
Sorry me for the lack information.
I am using MPLAB 8.92 and C30 compiler.
I don't know that I add a deelay.
I attacched eeprom_rw.h and eeprom_rw.s file.
If I would write a number like 55 in the first position and after read I must type:
WriteWord(0,55);
a=ReadWord(0);
But this code...
Hi,
actually I'm using eeprom_rw.h library developed by btbass but it doesn't work.
I debugged my simple program carefully and the EEPROM's values doesn't change.
Someone have a solution?
Thanks
