Where to begin MSP430 Flash programming?

How can i write to a flash segment safely in MSP430?

See the users guide flash controller section. Also, there are many threads about this in the forum. The search function helps finding them.

Does wrong programming destroys the controller?

No. It just leads to improperly written flash cells, which may reduce the retention time (down to zero, worst case). It may also reduce the maximum number of write cycles. But if your initial failures lead to a reduction from 100k to 10k write cycles, this surely won't be a big problem too,a s long as you don't carry the problem to the release version/mass production.

Thank you Jens-Michael Gross,

I went through some examples and forum posts but the most confusing part is how to find the address of Flash memory segments..i didn't find that in datasheet . I want to know about the address of Flash memory segments of

MSP430F5438A

In some code it says 0x0E000 and in some 0x1040 which one should i really choose.

Each datasheet contains a chapter named 'Memory address organization'. It's all there.

0xe000 is main flash. Likely, on the MSP for which this example was written, there is main flash from 0xe000 to 0xffff (16 k main flash). 0x1040 is one of the INFO segments. Main and Info flash are basically the same. The only differences are that you can mas-erase main flash only (spare the info flash) if you want, and that info memory has smaller flash segments (and is only 256 bytes to 1k, depending on MSP)
