hello
I have programmed the nor flash with the rcw generated from the pbl tool ,how to read the values that is in the nor flash
when i read 0XE8000000 I am finding 0xffffffff if when i am executing the commands i was able to read the device id
change p:e8000000 00f0 16bit
change p:e8000aaa 00aa 16bit
change p:e8000554 0055 16bit
change p:e8000aaa 0090 16bit
display p:e8000000..e8000004
display p:e8100000..e8100004
how to find that the code is written to the flash?
Hello agxin j,
You can either use dump of flash programer or ccs command to read back the flash content.

how to find that the code is written to the flash?
Source flash poke.tcl file is given for reading from freescale how is this code working ? To read the flash id is there any way to find if the flash is locked or not by reading
Hi Agxin
Did you try the mem command I mentioned above ?

Hi agxin
I don't have a CWTAP but you probably
have a "mem" command to display the
memory:
e.g.:
mem 0xe8000000 16
Let me know if this works.

Hi
What is the flash you are trying to program.
MT29F4G08ABADAWP you show in the log seems
to be a NAND flash and not a NOR flash.
What is the exact part number of the flash you
are trying to program.
