read/write nor flash memory...?

amarayya hiremath

Hi,

I want to read and write the nor flash but not as MTD(char or block) partition.

For ex:

I have my data 'A' I want it to write to some memory address for ex:0x0700001(address of nor flash). and read it using flash address ie 0x0700001.

That is I want to access nor flash memory directly with address. how to do this...??

My magic ball said that you cannot do that with MSP430.

1. use JTAG to connect your board and IDE like CCS to access the data, you can modify from a sample

2. use bootloader command to access

3. refer to MTD-utility and modify for your request when bootup with linux

I don't want to access at u-boot time.

I want to access the flash memory after kernel boot. I want to use it for storing my data as I said in my previous post.

and as I already mentioned in my previous post I Don't want to use the MTD-utility.

please see my previous 1st post and please answer to that...?

How do you expect to get answer here without specifying your development tool / MCU / kernel version?

This is not possible with Linux by default.

If I were the moderator I would give you warning and closed the topic.

There is no nor flash in beagleboard. How do you connect the memory?
