: Write to flash - raspa84 - Sep 8 5:38:25 2009
Hi,I'm doing a simple program that get temperature from the integrated sensor and store in
flash memory, using a msp430x20x3.I have no problem till I start at 0x1040 address and
writing 128 bytes, but when I start at 0x1200 my program doesn't work?Any idea?I also try
to looking for TI documentations,but there's no good application notes!
Thanks in advance

Try reading the chip data sheet. You need to write the data to an area of
the address space that is connected to physical flash memory.

I look at datasheets but I only see memory segmentation,nothing about address to physical
flash memory.

Thanks,I see.But every address I use out of 0x1040 seems it doesn't work!

Re: Re: : Write to flash - Ian Okey - Sep 8 10:50:17 2009
addresses 0x1000 -> 0x10FF are valid but are in 4 different sectors A,B,C&
D. If you erase just the first of these sectors then you can write in
addresses 0x1000 to 0x103F. Address 0x1040 will be in the first unerased
sector and you cannot write data here.
You really do not want to erase segment A as this contains factory
programmed calibration data for things like the clock generator
frequencies. Special commands are needed to erase this sector.

Re: : Write to flash - raspa84 - Sep 8 11:08:01 2009
Right!But following TI examples on flash writing, I see that address (0x1040) and I used
too.I try also to write my data at the address 0xF500,that it would be out of code and
informations address space,but it still not working!thank you for the patience!:)

Re: Re: : Write to flash - Ian Okey - Sep 8 11:12:58 2009
which chip are you actually using.
0xF500 is not a valid flash address for F2013 (lowest address is 0xF800) or
F2003 (Lowest flash address is 0xFC00). On these two devices there is no
memory at the address that you are specifying.

0xF500 is not a valid flash address for F2013 (lowest address is 0xF800) or
F2003 (Lowest flash address is 0xFC00). On these two devices there is no
memory at the address that you are specifying.

Re: : Write to flash - raspa84 - Sep 8 11:21:51 2009
I'm using eZ430 kit with the F2013.Ok,I'll read the documentations one more time,and try
to understand well these memory!Thank you for your help!
