Can NOR Flash be programmed by JTAG programmer using Memory Map

[adityanagal]

HI , 

I am working over IMX6 solo which is interfaced with NOR Flash and having JTAG interface. we have the compete schematics and know the memory map . Can i write the NOR flash by JTAG programmer using memory map of the NOR Flash. Please suggest.

Hi Aditya

NOR flash programming requires a special algorithm depending on the type

of the flash. This is usually described in your flash memory datasheet.

If your JTAG programmer already supports this then you should be able

program your flash on that board by providing its parameters to configure

your JTAG programmer.

Otherwise as Igor mentioned above, you would have to implement all that

initialization and the programming scripts.

We are using a BDI3000 JTAG Debugger here and had no problem programming

most NOR flashes on IMX6S based designs.

Hope this helps.

Hi Aditya

in general one can write the NOR flash by JTAG programmer, but for that

jtag scripts should be created (probably uboot codes may be reused).
