Data EEPROM Initialization with #rom

[INT01]

In the PIC16F886 to initialize the ROM (Flash EEPROM) I use:

#rom 0x2100={0xD0} ---> OK

In the PIC16F1937 I can't initialize the ROM using the #ROM command .

#rom 0x1E000={0xD0} ---> DON´T WORK

I know the address to use is 0x1E000, but can I do it? In the datasheet we can read:

7.3 Data EEPROM
The programmer should be able to read data memory information from a hex file and write data memory contents to a hex file. The physical address range of the 256 data memory is 0000h-00FFh. However, these addresses are logically mapped to address 1E000h-1E1FFh in the hex file.This provides a way of differentiating between the data and program memory locations in this range. The format for data memory storage is one data byte per address location, LSB aligned.


Any ideas? Another way to do this?

Thanks.

This is down to your programmer.

0x1E000, is the correct address. What programmer are you using to write the chip?. It does work with a PICKIT3.

Thanks for your fast reply Ttelmah:

I'm using PICKIT3.

What is your compiler version ?

Aargh.
Yes.
I was using the 'getenv' - tend to always use this now, and the hex file, showed the data at 0x1E000, forgot about the 'word versus byte' addressing issue, which is what is causing this. #ROM uses a word address value, while 1E000, is a byte address.
