erasing and programming nor flash

[jagxin]

dear all

                Is it possible to erase a nor flash connected to the elbc bus after connecting through the SRAM_INIT.tcl and running a task for erasing the flash ? or only we can read csan the flashing algorithm run using the l2 cache configured as sram

Hi agxin

Look at this in your log :

0 Bytes Programmed, Check Restricted Address Range

Are you sure your programming went OK? It seems you

might have to unlock the address range first - if Restricted

means this.

Hope this helps.

I have given restricted range from e8000000 to efffffff do we have to change this  address or the code what ever I am writing is written into the ram  instead of flash what should be the offset address and base address in the targeted task window

Hello agxin j，

In "PA Flash Programmer Task", please click "Add Action" and open "Add Program / Verify Action" Panel, you need to to select "Apply Address Offset" and specify the exact address where u-boot is located, for example "0xeff40000".

Have a great day,
Yiping

Programming went ok I have  unprotected first to write to the flash how to check the flash is locked or protected any command codes are there for checking

Hello agxin j,

Yes, it's possible.

Is the target P2041? I am afraid the l2 Cache could not be used as SRAM. If you're referring to CPC, they're configure as SRAM in P2041RDB_init_sram.tcl.

Have a great day,
Lunmin
